This is the history of Bangladesh. See also the history of South Asia, history of Asia, and history of present-day nations and states.

The area which is now Bangladesh has a rich historical and cultural past, combining Dravidian, Indo-Aryan, Mongol/Mughul, Arab, Persian, Turkic, and West European cultures. Residents of Bangladesh, about 98% of whom are ethnic Bengali and speak Bangla, are called Bangladeshis. Urdu-speaking, non-Bengali Muslims of Indian origin, and various tribal groups, mostly in the Chittagong Hill Tracts, comprise the remainder. Most Bangladeshis (about 88%) are Muslims, but Hindus constitute a sizable (11%) minority. There also are a small number of Buddhists, Christians, and animists. English is spoken in urban areas and among the educated.

Sufi religious teachers succeeded in converting many Bengalis to Islam, even before the arrival of Muslim armies from the west. About 1200 AD, Muslim invaders established political control over the Bengal region. This political control also encouraged conversion to Islam. Since then, Islam has played a crucial role in the region's history and politics, with a Muslim majority emerging, particularly in the eastern region of Bengal.

Bengal was absorbed into the Mughul Empire in the 16th century, and Dhaka, the seat of a nawab (the representative of the emperor), gained some importance as a provincial center. But it remained remote and thus a difficult to govern region--especially the section east of the Brahmaputra River--outside the mainstream of Mughul politics. Portuguese traders and missionaries were the first Europeans to reach Bengal in the latter part of the 15th century. They were followed by representatives of the Dutch, the French, and the British East India Companies. By the end of the 17th century, the British presence on the Indian subcontinent was centered in Calcutta. During the 18th and 19th centuries, the British gradually extended their commercial contacts and administrative control beyond Calcutta to Bengal. In 1858, the British Crown replaced the East India Company, extending British dominion from Bengal, which became a region of India, in the east to the Indus River in the west.

The rise of nationalism throughout British-controlled India in the late 19th century resulted in mounting animosity between the Hindu and Muslim communities. In 1885, the All-India National Congress was founded with Indian and British membership. Muslims seeking an organization of their own founded the All-India Muslim League in 1906. Although both the League and the Congress supported the goal of Indian self-government within the British Empire, the two parties were unable to agree on a way to ensure the protection of Muslim political, social, and economic rights. The subsequent history of the nationalist movement was characterized by periods of Hindu-Muslim cooperation, as well as by communal antagonism. The idea of a separate Muslim state gained increasing popularity among Indian Muslims after 1936, when the Muslim League suffered a decisive defeat in the first elections under India's 1935 constitution. In 1940, the Muslim League called for an independent state in regions where Muslims were in the majority. Campaigning on that platform in provincial elections in 1946, the League won the majority of the Muslim seats contested in Bengal. Widespread communal violence followed, especially in Calcutta.

When British India was partitioned and the independent dominions of India and Pakistan were created in 1947, the region of Bengal was divided along religious lines, echoing a short-lived division into two provinces in 1905-1912 which had provoked violent nationalist opposition. The predominantly Muslim eastern half was designated East Pakistan - and made part of the newly independent Pakistan - while 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 constiturion was at last adopted, making the country an "Islamic republic within the Commonwealth". Attempts at civilian political rule foundered in the face of military intervention from October 1958, and the government imposed martial law between 1958 and 1962, and again between 1969 and 1972.

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. Bengalis strongly resisted attempts to impose Urdu as the sole official language of Pakistan. Responding to these grievances, Sheikh Mujibur Rahman in 1949 formed the Awami League, a party designed mainly to promote Bengali interests. Mujib became president of the Awami League and emerged as leader of the Bengali autonomy movement. In 1966, he was arrested for his political activities.

After the Awami League won all the East Pakistan seats of the Pakistan national assembly in 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. Mujib was arrested again; his party was banned, and most of his aides fled to India, where they organized a provisional government. On March 26, 1971, following a bloody crackdown by the Pakistan army, Bengali nationalists declared an independent People's Republic of Bangladesh. As fighting grew between the army and the Bengali mukti bahini ("freedom fighters"), an estimated 10 million Bengalis, mainly Hindus, sought refuge in the Indian states of Assam 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, India intervened on the side of the Bangladeshis. On December 16, 1971, Pakistani forces surrendered, and Bangladesh ("Bengal nation") 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.

In January 1975 economic and political difficulties led to Sheikh Mujib's assumption of the presidencey with greatly increased powers. On August 15, he was killed in a military coup. Following two further coups (November 3 and 6), Maj. Gen. Zia ur-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 Lt. Gen. Hussain Mohammad Ershad took power, holding office until his resignation (December 6, 1990) amid corruption allegations. The Bangladesh Nationalist Party of Khaleda Zia, Gen. Zia's widow, won power in the subsequent elections (February 1991) but was driven from office five years later, the rival Awami League returning to power in subsequent elections (June 1996) under Mujib's daughter Hasina Wazed.
