History of Bangladesh...

Bangladesh became one of the youngest major nation states following a pair of twentieth century secessions from India (1947) and Pakistan (1971). The region's history combines Indo-Aryan, Austro-Asiatic, Dravidian, Mughal, Arab,Persian, Turkic and British influences. Bangladesh's territory became part of the state of Bengal as part of the Mughal Empire for two centuries and also during the succeeding two centuries of British rule. During the twentieth century, its resilient inhabitants seem to have suffered one trauma after another. Sheikh Mujibur Rahman (Mujib) led the nation to independence in 1971, but he and his successor Ziaur Rahman (Zia) were both assassinated only in a span of six years. Their legacies (and families) define Bangladesh's democracy to this day.

Etymology

The exact origin of the word Bangla or Bengal is unknown, though it is believed to be derived from the Dravidian-speaking tribe Bang that settled in the area around the year 1000 BCE.
Other accounts speculate that the name is derived from Vanga(bôngo), which came from the Austral word "Bonga" meaning the Sun-god. According to Mahabharata, Purana, Harivamsha Vanga was one of the adopted sons of king Vali who founded the Vanga kingdom. The Muslim Accounts refer that "Bong", a son of Hind (son of Ham who was a son of Noah) colonized the area for the first time. The earliest reference to "Vangala"(bôngal) has been traced in the Nesari plates (805 AD) of Rashtrakuta Govinda III which speak of Dharmapala as the king of Vangala. Shams-ud-din Ilyas Shah took the title "Shah-e-Bangalah" and united the whole region under one nationality for the first time.[citation needed]

Ethnology

The Proto-Australoids were the earliest inhabitants of Bengal. Dravidians migrated to Bengal from Southern India, while Tibeto-Burman people migrated from the Himalayas, followed by the Indo-Aryans from north-western India. The ancestors of modern Bengali people were a blend of these peoples. Pathans, Iranians, Arabs and Turks also migrated to the region in the late middle Ages while spreading Islam.

Ancient period

The Alpine civilization

Remnants of civilization in the greater Bengal region date back three millennia. The civilization that flourished in this region before the Aryan conquest was the Alpine civilization. The Alpines (Eastern Bracycephalic) from Taklamakan Desert in Central Asia settled in eastern India (Bengal, Orissa and the plains of Assam) and formed the main elements of today's Bengali people. The Alpines were divided into various indigenous tribes: Vanga (south Bengal), Pundra (north Bengal), and Rarh/Suhma (West Bengal) according to their respective Totems.
Not much is known about this civilization. Some deprecatory references indicate that the primitive people in Bengal ware different in ethnicity and culture form the Vedic beyond the boundary of Aryandom and who were classed as 'Dasyus'. The Bhagavata Purana classes them as sinful people while Dharmasutra of Bodhayana prescribes expiatory rites after a journey among the Pundras and Vangas. However, the Alpines successfully resisted the Vedic Aryan invaders for about a millennium. It was only in the 4th century BCE when aryanism started to flux into this region with the Mauryan conquest.

Overseas Colonization

According to Mahavamsa, Vijaya Singha, a Vanga prince, conquered Lanka (modern day Sri Lanka) in 544 BC and gave the name Sinhala to the country. Bengali people also colonized Laat(Gujarat), Madras and the Indonesian archipelago. The Chera, Tamil, Andhra and Karnataka people are also said to be connected with the Bengalis.

Few Naga worshipping peoples--Marana, Chera, Pangalathirayar--migrated from Bengal to South India and established their own kingdoms there. Lac Long Quan, a Naga warrior migrated from bôn-lang(Bengal) to Anam (Vietnam) conquered the land (7th century BCE) and renamed it according to the name of his motherland (bon-lang). The kings of Lac Long's line were known as bôns (Bongs)and they would rule Anam up to the 3rd century BCE.

Gangaridai Empire

In 326 BCE, with the invasion of Alexander the Great the region again comes into prominence. The Greek and Latin historians suggested that Alexander the Great withdrew from India anticipating the valiant counter attack of the mighty Gangaridai and Prasioi empires which were located in the Bengal region. Alexander, after the meeting with his officer, Coenus, was convinced that it was better to return. Diodorus Siculus mentions Gangaridai to be the largest and the most powerful empire in India whose king possessed an army of 20,000 horses, 200,000 infantry, 2,000 chariots and 4,000 elephants trained and equipped for war. The allied forces of Gangaridai and Prasii (Nanda Empire) were preparing a massive counter attack against the forces of Alexander on the banks of Ganges. Gangaridai according to the Greek accounts kept on flourishing at least up to the 1st century AD.

Early Middle Ages

The pre-Gupta period of bengal is shrouded with obscurity. Before the conquest of Samudragupta Bengal was divided into two kingdoms Pushkarana and Samatata. Chandragupta II had to defeat a confederacy of Vanga kings. Bengal was a part of the Gupta Empire. However, the Mrigashikhaban Stupa of Varendra is a strong proof that the Guptas themselves had originated from Bengal. This implies that the Guptas were Bengali and the Gupta empire was in fact a Bengali empire. Even today the origin of the Guptas is still hotly debated.

Gupta Empire

Maharaja Sri-Gupta the founder of the dynasty probably ruled a portion of Northern or Central Bengal. Later, the Guptas extended their dominion as far as Magadha, Prayaga, and Saket(Ayodhya). Samudragupta and Chandragupta II were two celibrated kings of the empire. Gupta Age is often consudered as the Golden Age of India by modern historians. The Guptas, already weakened by the Hephthalite invasions was finally brought to an end by Yasodharman of Malwa. Factions of the Gupta dynasty, however, survived in Bengal where they will later form the Gauda kingdom.

Gauda Kingdom

By the sixth century, the Gupta Empire ruling over the northern Indian subcontinent was largely broken up. Eastern Bengal became the Vanga kingdom while the Gauda kings rose in the west with their capital at Karnasuvarna (Murshidabad). The first two kings of Independent Gauda kingdom Kumargupta and Damodargupta consolidated their power in Gaur and Magadha. Mahasengupta the greatest king of this dynasty not only expanded his kingdom to the Brahmaputra valley in Assam but also to Malava in Central India. Shashanka the successor of Mahasengupta unified the smaller principalities of Bengal (Gaur, Vanga, Samatata) and vied for regional power with Harshavardhana in northern India. But this burst of Bengali power did not last beyond his death, as Bengal descended afterwards into a period marked by disunity and foreign invasion.

The Pala Empire

The first independent Buddhist king of Bengal, Gopala I came to power in 750 in Gaur by democratic election. Gopala founded the Buddhist Pala dynasty which lasted for four centuries (750-1120 AD), ushering in a period of relative stability and prosperity. At its peak, under Dharmapala the empire extended into much of Bihar and once more wrestled for control of the subcontinent. He conquered Bhoja (Berar), Matsya (Jaipur), Madra (Central Punjab), Kuru (Thaneswar), Yadu (Mathura & Dwaraka), Avanti (Malwa), Yavana(Muslims of Sindh/Multan), Gandhara (Kabol valley), Kambojja (Northern Bengal ruled by Barman kings; later after the fall of Kambojja, another Kambojja was born -- Cambodia, ruled by Barmans) and Kira (Kangra).
Devapala the Great, successor of Dharmapala, expanded his empire farther up to Assam and Utkala in the east, Kamboja in the north-west and Deccan in the south. He exterminated the Utkalas, conquered the Pragjyotisha (Assam) shattered the pride of the Huna and humbled the lords of GurjaraPratiharas and the Dravidas.
The Pala empire can be considered as the Roman empire of Bengal. Never had the Bengali people reached such height of power and glory and never had they influenced the outside world to that extent. Palas were responsible for the introduction of Mahayana Buddhism in Tibet, Bhutan, Myanmar. The pre-dominant Pala sculptures and the proto-Bangla scripts of the Sailendra empire (Malaya, Java, Sumatra) of the late 8th century attest that the Sailendra dynasty originated from Bengal.
The death of Devapala ended the period of ascendancy of the Pala empire and several independent dynasties and kingdoms emerged during this time including the Khadgas, Devas, the Chandras, and Varmanas. Mahipala I rejuveneted the reign of the Palas. He recovered north Bengal from the Kambojas and survived the invasions of Rajendra Chola and the Chalukyas. Mahipala I did not join the Hindu confederacy against Mahmud of Ghazni.
After Mahipala I the Pala dynasty again saw its decline until Ramapala,the last great ruler of the dynasty, managed to retrieve the position of the dynasty to some extent. He crushed the Varendra rebellion and extended his empire farther to Kamarupa, Orissa and Northern India.
The Palas were followed by the Sena dynasty who brought the East and West Bengal under one ruler only during the twelfth century. The Sena dynasty brought a revival of Hinduism and cultivated Sanskrit literature.


Late Middle Ages - Arrival of Islam

Islam made its first appearance in Bengal during the twelfth century AD when Sufi missionaries arrived. Later occasional Muslim invaders reinforced the process of conversion by building mosques, madrassas and Sufi Khanqahs. Beginning in 1202 a military commander from the Delhi Sultanate, Ikhtiar Uddin Muhammad bin Bakhtiar Khilji, overran Bihar and Bengal as far east as Rangpur, Bogra and the Brahmaputra River. The defeated Laksmanasena and his two sons moved to a place then called Vikramapura (south of Dhaka), where their diminished dominion lasted until the late thirteenth century.

Turkic dynasties

The period after Bakhtiar Khilji's death in 1206 devolved into infighting among the Khiljis - representative of a pattern of succession struggles and intra-empire intrigues during later Turkish regimes. Ghiyasuddin Iwaz Khalji prevailed and extended the Sultan's domain south to Jessore and made the eastern Bang province a tributary. The capital was made at Lakhnauti on the Ganges near the older Bengal capital of Gaur. He managed to make Kamarupa, Orissa and Trihut pay tribute to him. But he was later defeated by Shams-ud-Din Iltutmish.
The weak successors of Iltutmish encouraged the local governors to declare independence. Bengal was sufficiently remote from Delhi that its governors would declare independence on occasion, styling themselves as Sultans of Bengal. It was during this time that Bengal earned the name "Bulgakpur"(land of the rebels). Tughral Togun Khan added Oudh and Bihar to Bengal. Mughisuddin Yuzbak also conquered Bihar and Oudh from Delhi but was killed during an unsuccessful expedition in Assam.
Two Turkish attempts to push east of the broad Jamuna and Brahmaputra rivers were repulsed, but a third led by Mughisuddin Tughral conquered the Sonargaon area south of Dhaka to Faridpur, bringing the Sena Kingdom officially to an end by 1277. Mughisuddin Tughral repulsed two massive attacks of the sultanate of Delhi before finally being defeated and killed by Ghiyas ud din Balban.

Ilyas Shahi dynasty

Ilyas Shah founded an independent dynasty that lasted from 1342-1487 which successfully repulsed attempts by Delhi to reign them in. They continued to reel in the territory of modern-day Bengal, reaching to Khulna in the south and Sylhet in the east. The sultans advanced civic institutions and became more responsive and "native" in their outlook, having cut loose from Delhi. Considerable architectural projects were completed in Gaur including the massive Adina Mosque and the 1479 Darasbari Mosque which still stands in Bangladesh near the border. The Sultans of Bangalah were patrons of Bengali literature and began a process in which a common Bengali culture and identity would coalesce.
The Ilyas Shahi Dynasty was interrupted by an uprising of the Hindus under Ganesh. However the Ilyas Shahi dynasty was restored by Nasiruddin Mahmud Shah, which was finally overthrown by the Habshi (Abyssinian) slaves of the sultanate.

Hussain Shahi dynasty

The Habshi rule gave way to the Hussain Shahi dynasty that ruled from 1494-1538. Alauddin Hussain Shah, considered as the greatest of all the sultans of Bengal for the cultural renaissance during his reign, conquered Kamarupa, Kamata, Jajnagar, Orissa and extended the sultanate all the way to the port of Chittagong, which witnessed the arrival of the first Portuguese merchants.
Nasiruddin Nusrat Shah gave refuge to the Afghan lords during the invasion of Babur though he remained neutral. However Nusrat Shah made a treaty with Babur and saved Bengal from a Mughal invasion.
The last Sultan of the dynasty, who continued to rule from Gaur, had to contend with rising Afghan activity on his northwestern border. Eventually, the Afghans broke through and sacked the capital in 1538 where they remained for several decades until the arrival of the Mughals.

Afghan rule

Sher Shah Suri established the Sur dynasty in Bengal. After the battle of Chausa he declared himself independent Sultan of Bengal and Bihar. Sher Shah was the only Muslim Sultan of Bengal to establish an empire in northern India. The Afghan rule in Bengal remained for 44 years. Their most impressive achievement was Sher Shah's construction of the Grand Trunk Road connecting Sonargaon, Delhi and Peshawar.
The Sur dynasty was followed by the Karrani dynasty. Sulaiman Karrani annexed Orissa to the Muslim sultanate permanently. Daud Shah Karrani declared total independence from Akbar which led to four years of bloody war between the Mughals and the Afghans. The Mughal onslaught against the Afghan Sultan ended with the battle of Rajmahal in 1576, led by Khan Jahan. However, the Afghans and the local land-lords (Baro Bhuyans) led by Isa Khan resisted the Moghul invasion.

Mughal period

Bengal came once more under the suzerainty of Delhi as the Mughals conquered it in 1576. Not far from Sonargaon, Dhaka rose from the mists of obscurity as a Mughal provincial capital. But it remained remote and thus a difficult to govern region--especially the section east of the Brahmaputra River--outside the mainstream of Mughal politics. The Bengali ethnic and linguistic identity further cystallized during this period, since the whole of Bengal was united under an able and long-lasting administration. Furthermore its inhabitants were given sufficient autonomy to cultivate their own customs and literature.
In 1612, during Emperor Jahangir's reign, the defeat of Sylhet completed the Mughal conquest of Bengal, except for Chittagong. At this time the capital was established at Dhaka. Chittagong was later annexed in order to stifle Arakanese raids from the east. A well-known Dhaka landmark, Lalbagh Fort was built during Aurangzeb's sovereignty as well.
History repeated itself as the frontier Bengal province broke off from a Delhi-based empire around the time Aurangzeb's death in 1707. Murshid Quli Khan ended Dhaka's century of grandeur as he shifted the capital to Murshidabad ushering in a series of independent Bengal Nawabs. Nawab Alivardi Khan showed extra ordinary militarimanship during his wars with the Marathas. He completely routed the Marathas from Bengal. He crushed an uprising of the Afghans in Bihar and made the British pay 150,000 Tk for blocking Mughal and Armenian trade ships.

Europeans in Bengal

Portuguese traders and missionaries were the first Europeans to reach Bengal in the latter part of the fifteenth century. They were followed by representatives of the Dutch, the French, and the British East India Company. The Mughal Subahdar of Bengal Kasim Khan Mashadi completely destroyed the Portuguese in the Battle of Hoogly (1632). About 10,000 Portuguese men and women died in the battle and 4,400 were sent captive to Delhi.
During Aurangzeb's reign, the local Nawab sold three villages, including one then known as Calcutta, to the British. Calcutta was in fact Britain's initial foothold on the Indian subcontinent and remained a focal point of their activity. The British gradually extended their commercial contacts and administrative control beyond Calcutta to the rest of Bengal. Job Charnock was one of the first dreamers of a British empire in India. He almost waged war against the Mughal authority of Bengal which led to the Anglo-Mughal war of Bengal (1686-1690). Shaista Khan the nawab of Bengal defeated the British in the battles of Hoogly, Baleshwar, and Hijly and expelled the British from Bengal. Captain William Heath with a fleet moved towards Chittagong but it was a failure and he had to retreat to Madras.

British Rule

The British East India Company gained official control of Bengal following the Battle of Plassey in 1757. This was the first conquest, in a series of engagements that ultimately lead to the expulsion of other European competitors, the defeat of the Mughals and the consolidation of the subcontinent under the rule of a corporation -- a doubly unique event. Calcutta (nowadays Kolkata) on the Hooghly became a major trading port for the Muslin and Jute produced in Dhaka and the rest of Bengal.
Scandals and the bloody rebellion known as the Sepoy Mutiny prompted the British government to intervene in the affairs of the East India Company. In 1858, authority in India was transferred from the Company to the crown and the rebellion was brutally suppressed. Rule of India was organized under a Viceroy and continued a pattern of economic exploitation. Famine racked the subcontinent many times, including at least two major famines in Bengal. The British Raj was politically organized into seventeen Provinces--of which Bengal was one of the most significant--most headed by a Governor. For a brief period in the early twentieth century, an abortive attempt was made to divide Bengal into two zones, West Bengal and East Bengal & Assam.


Creation of Pakistan

As the independence movement throughout British-controlled India began in the late nineteenth century gained momentum during the twentieth century, Bengali politicians played an active role in Gandhi's Congress Party and Jinnah's Muslim League, exposing the opposing forces of ethnic and religious nationalism. By exploiting the latter, the British probably intended to distract the independence movement, for example by partitioning Bengal in 1905 along religious lines (the split only lasted for seven years). At first the Muslim League sought only to ensure minority rights in the future nation. In 1940 the Muslim League passed the Lahore Resolution which envisaged one or more Muslim majority states in South Asia. Non-negotiable was the inclusion of the Muslim parts of Punjab and Bengal in these proposed states. The stakes grew as a new Viceroy Mountbatten was appointed expressly for the purpose of effecting a graceful British exit. Communal violence in Noakhali and Calcutta sparked a surge in support for the Muslim League, which won a majority of Bengal's Muslim seats in 1946. Accusations have been made that Hindu and Muslim nationalist instigators were involved in the latter incident. At the last moment Suhrawardy and Sarat Chanderbose came up with the idea of an Independent and Unified Bengal state, which was endorsed by Jinnah. This idea was vetoed by the Indian National Congress.
British India was partitioned and the independent states of India and Pakistan were created in 1947; the region of Bengal was divided along religious lines. The predominantly Muslim eastern half of Bengal became the East Bengal (later renamed East Pakistan) state of Pakistan and the predominantly Hindu western part became the Indian state of West Bengal.
Pakistan's history from 1947 to 1971 was marked by political instability and economic difficulties. In 1956 a constitution was at last adopted, making the country an "Islamic republic within the Commonwealth". The nascent democratic institutions foundered in the face of military intervention in 1958, and the government imposed martial law between 1958 and 1962, and again between 1969 and 1971.
Almost from the advent of independent Pakistan in 1947, frictions developed between East and West Pakistan, which were separated by more than 1,000 miles of Indian territory. East Pakistanis felt exploited by the West Pakistan-dominated central government. Linguistic, cultural, and ethnic differences also contributed to the estrangement of East from West Pakistan.
When Mohammad Ali Jinnah died in September 1948, Khwaja Nazimuddin became the Governor General of Pakistan while Nurul Amin was appointed the Chief Minister of East Bengal. Nurul Amin continued as the Chief Minister of East Bengal until 2 April 1954. The abolition of the Zamindari system in East Bengal (1950) and the Language Movement were two most important events during his tenure.

The Bengali Language Movement

The question as to what would be the state language of Pakistan was raised immediately after its creation. The central leaders and the Urdu-speaking intellectuals of Pakistan declared that Urdu would be the state language of Pakistan, just as Hindi was the state language of India. However, Bengalis strongly resisted attempts to impose Urdu as the sole official language of Pakistan, and the students and intellectuals of East Pakistan, demanded that Bengali (Bangla) be made one of the state languages, arguing that it was in any case the native language of the majority (54% native speakers as opposed to 7% native Urdu speakers) in the whole of Pakistan.
The Bengali Language Movement began in 1948 and reached its climax in a demonstration on 21 February 1952 at which several demonstrators were killed by police. After a lot of controversy over the language issue, the final demand from East Pakistan was that Bangla must be the official language and the medium of instruction in East Pakistan, and that for the central government it would be one of the state languages along with Urdu. The first movement on this issue was mobilised by Tamaddun Majlish headed by Professor Abul Kashem. Gradually many other non-communal and progressive organisations joined the movement, which finally turned into a mass movement, and ended in the adoption of Bangla as one of the state languages of Pakistan.

Politics: 1954 - 1970

The first election for East Bengal Provincial Assembly was held between 8 March and 12 March 1954. The Awami Muslim League, Krishak-Sramik Party and Nezam-e-Islam formed the United Front, on the basis of 21-points agenda.
Notable pledges contained in the 21-points were:

* making Bangla one of the state languages
* autonomy for the province
* reforms in education
* independence of the judiciary
* making the legislative assembly effective, etc.

The United Front won 215 out of 237 Muslim seats in the election. The ruling Muslim League got only nine seats. Khilafat-E-Rabbani Party got one, while the independents got twelve seats. Later, seven independent members joined the United Front while one joined the Muslim League.
There were numerous reasons for the debacle of the Muslim League. Above all, the Muslim League regime angered all sections of the people of Bengal by opposing the demand for recognition of Bangla as one of the state languages and by ordering the massacre of 1952.
The United Front got the opportunity to form the provincial government after winning absolute majority in the 1954 election. Of the 222 United Front seats, the Awami Muslim League had won 142, Krishak-Sramik Party forty eight, Nezam-i-Islam]nineteen and Ganatantri Dal thirteen.
The major leaders of the United Front were Huseyn Shaheed Suhrawardy and Maulana Abdul Hamid Khan Bhasani of Awami Muslim League and A. K. Fazlul Huq of Krishak-Sramik Party. Suhrawardy and Bhasani did not take part in the election and Fazlul Huq was invited to form the government. But a rift surfaced at the very outset on the question of formation of the cabinet. The unity and solidarity among the component parties of the United Front soon evaporated. Finally, on 15 May, Fazlul Huq arrived at an understanding with the Awami Muslim League and formed a 14-member cabinet with five members from that party.
But this cabinet lasted for only fourteen days. The Muslim League could not concede defeat in the elections in good grace. So, they resorted to conspiracies to dismiss the United Front government. In the third week of May, there were bloody riots between Bengali and non-Bengali workers in different mills and factories of East Bengal. The United Front government was blamed for failing to control the law and order situation in the province.
Fazlul Huq was then quoted in an interview taken by the New York Times correspondent John P Callaghan and published in a distorted form that he wanted the independence of East Bengal. Finally, on 29 May 1954, the United Front government was dismissed by the central government and Governor's rule was imposed in the province, which lasted till 2 June 1955.
Curiously enough within two months of his sacking, Fazlul Huq was appointed the central Home Minister. As Home Minister, Fazlul Huq utilised his influence to bring his party to power in East Bengal. Naturally, the United Front broke up. The Muslim members of the United Front split into two groups. In 1955 the Awami Muslim League adopted the path of secularism and non-communalism, erased the word 'Muslim' from its nomenclature and adopted the name of Awami League. (Source: Banglapedia.)
Great differences began developing between the two wings of Pakistan. While the west had a minority share of Pakistan's total population, it had the maximum share of revenue allocation, industrial development, agricultural reforms and civil development projects. Pakistan's military and civil services were dominated by the fair-skinned, Persian-cultured Punjabis and Afghans. Only one regiment in the Pakistani Army was Bengali. And many Bengali Pakistanis could not share the natural enthusiasm for the Kashmir issue, which they felt was leaving East Pakistan more vulnerable and threatened as a result.

Independence

After the Awami League won all the East Pakistan seats of the Pakistan's National Assembly in the 1970-71 elections, West Pakistan opened talks with the East on constitutional questions about the division of power between the central government and the provinces, as well as the formation of a national government headed by the Awami League.
The talks proved unsuccessful, however, and on March 1, 1971, Pakistani President Yahya Khan indefinitely postponed the pending national assembly session, precipitating massive civil disobedience in East Pakistan.
In March 4, a group of students, lead by Abdur Rob, of Dhaka University raised the new (proposed) flag of Bangla.
In March 7, there was a historical public gathering in Paltan Maidan to hear the guideline for the revolution and independence from Shaikh Mujib, the frontier leader of movement that time. Though he avoided the direct speech of independent as the talks were still on table, he influenced the mob to prepare for the separation war. The speech without the script is still an epic speech for the war of liberation. A hit dialog of that speech is, "Now the revolution for independence, now the revolution for freedom...".
After the military crackdown by the Pakistan army since the night of March 25, 1971 Sheikh Mujib Mujibur Rahman was arrested and the political leaders dispersed, mostly fleeing to neighbouring India where they organized a provisional government afterwards. The people were at a loss. At this crucial moment with a sudden forced political vacuum, the Eighth East Bengal Regiment under the leadership of Major Ziaur Rahman revolted against the Pakistan Army and took up the Bangladesh flag as its mainstay on the night of March 26 - March 27, 1971. Major Zia declared, on behalf of the Great Leader Sheikh Mujibur Rahman, the independence of Bangladesh.
The Bangladesh Government was formed in Meherpur, adjacent to Indian border. There the war plan was sketched.
A war force was established named "Muktibahini". M. A. G. Osmani was assigned as the Chief of the force. The land sketched into 11 sectors under 11 sector commanders. Major Ziaur Rahman was the sector commander of Chittagong-Comilla region.
The training and most of the arms-ammunitions were arranged by the Meherpur government which were supported by India.
As fighting grew between the army and the Bengali Mukti Bahini ("freedom fighters"), an estimated ten million Bengalis, mainly Hindus, sought refuge in the Indian states of Assam, Tripura and West Bengal.
The crisis in East Pakistan produced new strains in Pakistan's troubled relations with India. The two nations had fought a war in 1965, mainly in the west, but the refugee pressure in India in the fall of 1971 produced new tensions in the east. Indian sympathies lay with East Pakistan, and on December 3, 1971, India intervened on the side of the Bangladeshis. On December 16, 1971, Pakistani forces surrendered, and Bangladesh ("Country of Bangla") was finally established the following day. The new country changed its name to Bangladesh on January 11, 1972 and became a parliamentary democracy under a constitution. Shortly thereafter on March 19 Bangladesh signed a friendship treaty with India.

Post-Independence

In January 1975 economic and political difficulties led to Sheikh Mujib's assumption of the presidencey with greatly increased powers and he also nulled multi-party system by creating one party rule. On August 15, 1975, he was killed in a military coup.
The success of Bengali nationalism also bred suspicion among the inhabitants of the Chittagong Hill Tracts. Manobendra Narayan Larma, a Chakma leader, asked Sheikh Mujib to grant autonomy to the Hill Tracts. He refused, saying, "We are all Bangalis". This statement was certainly true of the Chakmas - who speak a variant Bengali dialect- but the result achieved was the opposite intended: a fictive enthnicity led to armed struggle in the Hill Tracts until the late 1990s.
Following two further coups (November 3 and November 6), Major General Ziaur Rahman emerged as de facto ruler, assuming the presidency in April 1977. In May 1981, Zia in turn fell victim to a failed coup attempt; ten months later, on March 24, 1982, Lt. General Hossain Mohammad Ershad took power, holding office until his resignation (December 6, 1990) that was engineered by western donors who now felt that, with the Communist threat gone, they could do without dictators.
Bangladesh had known only four years of democracy after its inception; now the experiment was resumed - once again to end in military rule in 2007. The Bangladesh Nationalist Party (BNP) of Khaleda Zia, General Zia's widow, won power in the elections held in February 1991. The next election in June 1996 was won by the rival Awami League under Mujib's daughter Sheikh Hasina. In 2001, a four-party alliance including Khaleda Zia's BNP and Jamaat-e-Islami, returned to power after a landslide victory in the polls.
