Bangladesh

Bangladesh, officially the People's Republic of Bangladesh, is a country in South Asia. It is the eighth-most populous country in the world and among the most densely populated with a population of over 171 million within an area of 148,460 square kilometres (57,320 sq mi). Bangladesh shares land borders with India to the north, west, and east, and Myanmar to the southeast. It has a coastline along the Bay of Bengal to its south and is separated from Bhutan and Nepal by the Siliguri Corridor, and from China by the Indian state of Sikkim to its north. Dhaka, the capital and largest city, is the nation's political, financial, and cultural centre. Chittagong is the second-largest city and the busiest port of the country.

The territory of modern Bangladesh was a stronghold of many Buddhist and Hindu dynasties in ancient history. Following the Muslim conquest in 1204, the region saw Sultanate and Mughal rule. During the Mughal period, particularly under the Bengal Subah, the region emerged as one of the most prosperous and commercially active parts of the empire, known for its thriving textile industry and agricultural productivity. The Battle of Plassey in 1757 marked the beginning of British colonial rule for the following two centuries. In the aftermath of the Partition of British India in 1947, East Bengal became the eastern and most populous wing of the newly formed Dominion of Pakistan and was later renamed to East Pakistan.

Following over two decades of political repression and systemic racism from the West Pakistan-based government, East Pakistan experienced a civil war in 1971; ultimately leading to a war for independence. The Mukti Bahini, with assistance from Indian forces, waged a successful armed revolution; and despite a genocide perpetrated by Pakistan, Bangladesh became a sovereign nation on 16 December 1971. Post-Independence, Sheikh Mujibur Rahman led the country until his assassination in 1975. Presidency was later transferred to Ziaur Rahman, who himself was assassinated in 1981. The 1980s was dominated by the dictatorship of Hussain Muhammad Ershad, who was overthrown in a mass uprising in 1990. Following the democratisation in 1991, the "Battle of the Begums" between Khaleda Zia and Sheikh Hasina defined the country's politics for the next three decades. Hasina was overthrown in a student–led mass uprising in August 2024, and an interim government led by Nobel laureate Muhammad Yunus was formed.

Bangladesh is a unitary parliamentary republic based on the Westminster system. It is a middle power with the second-largest economy in South Asia. Bangladesh is home to the third-largest Muslim population in the world. It maintains the third-largest military in South Asia and is the largest contributor to the peacekeeping operations of the United Nations. It consists of eight divisions, 64 districts, and 495 sub-districts, and is home to the largest mangrove forest in the world. However, Bangladesh has one of the largest refugee populations in the world and continues to face challenges such as endemic corruption, lack of human rights, political instability, overpopulation, and adverse effects of climate change. It has twice chaired the Climate Vulnerable Forum and is a member of BIMSTEC, SAARC, OIC and the Commonwealth of Nations.

The etymology of Bangladesh ("Bengali country") can be traced to the early 20th century, when Bengali patriotic songs, such as Aaji Bangladesher Hridoy by Rabindranath Tagore and Namo Namo Namo Bangladesh Momo by Kazi Nazrul Islam, used the term in 1905 and 1932 respectively. Starting in the 1950s, Bengali nationalists used the term in political rallies in East Pakistan.

The term Bangla is a major name for both the Bengal region and the Bengali language. The origins of the term Bangla are unclear, with theories pointing to a Bronze Age proto-Dravidian tribe, and the Iron Age Vanga Kingdom. The earliest known usage of the term is the Nesari plate in 805 AD. The term Vangala Desa is found in 11th-century South Indian records. The term gained official status during the Sultanate of Bengal in the 14th century. Shamsuddin Ilyas Shah proclaimed himself as the first "Shah of Bangala" in 1342. The word Bangāl became the most common name for the region during the Islamic period. 16th-century historian Abu'l-Fazl ibn Mubarak mentions in his Ain-i-Akbari that the addition of the suffix "al" came from the fact that the ancient rajahs of the land raised mounds of earth in lowlands at the foot of the hills which were called "al". This is also mentioned in Ghulam Husain Salim's Riyaz-us-Salatin.

The Indo-Aryan suffix Desh is derived from the Sanskrit word deśha, which means "land" or "country". Hence, the name Bangladesh means "Land of Bengal" or "Country of Bengal".

The first great indigenous empire to cover the territory was the Maurya Empire (c. 320–185 BC). Following its decline, the kingdom of Samatata arose, which was a tributary state of the Gupta Empire (ca. 319-ca. 540 AD). Harsha (606–47 AD) drew Samatata into its loosely administered political structure. The Buddhist Pala Empire ruled the region from 750 to 1150 AD. It was overthrown by the Hindu Sena dynasty, which ruled the territory until the Muslim conquests led by Muhammad Bakhtiyar Khalji of the Ghurid dynasty in 1204.
