The earliest reference to "Vangala" knows as Bôngal

Modern Bangladesh emerged as an independent nation in 1971 after achieving independence from Pakistan in the Bangladesh Liberation War. The country constitutes with the major portion of the ancient and historic region of Bengal in the eastern part of the Indian subcontinent, where civilization dates back over four millennia, to the Copper Age. The history of the region is closely intertwined with the history of Bengal and the history of India.

The area's early history featured a succession of Indian empires, internal squabbling, and a tussle between Hinduism and Buddhism for dominance. Islam made its appearance during the 8th century when Sufi missionaries arrived. Later, Muslim rulers reinforced the process of conversion by building mosques, madrassas and Sufi Khanqah.

The borders of modern Bangladesh were established with the partition of Bengal and India in August 1947, when the region became East Pakistan as a part of the newly formed State of Pakistan following the Radcliffe Line.However, it was separated from West Pakistan by 1,600 km (994 mi) of Indian territory. Due to political exclusion, ethnic and linguistic discrimination, as well as economic neglect by the politically dominant westerin-wing, popular agitation and civil disobedience led to the war of independence in 1971. After independence, the new state endured famine, natural disasters and widespread poverty, as well as political turmoil and military coups. The restoration of democracy in 1991 has been followed by relative calm and economic progress.

Etymology of Bengal

The exact origin of the word Bangla or Bengal is unknown. According to Mahabharata, Purana, Harivamsha Vanga was one of the adopted sons of King Vali who founded the Vanga Kingdom.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 government for the first time. The Vanga Kingdom (also known as Banga) was located in the eastern part of the Indian Subcontinent, comprising part of West Bengal, India and present-day modern Bangladesh. Vanga and Pundra were two dominant tribes in Bangladesh in ancient time.

Ancient period

The ruins of Wari-Bateshwar in Narsingdi is believed to be from the copper age. Many of archeological excavations in Bangladesh revealed evidences of the Northern Black Polished Ware culture (abbreviated NBPW or NBP) of the Indian Subcontinent (c. 700–200 BC) which was an Iron Age culture developed beginning around 700 BC and peaked from c. 500–300 BC, coinciding with the emergence of 16 great states or mahajanapadas in Northern India, and the subsequent rise of the Mauryan Empire. The eastern part of ancient India, covering much of current days Bangladesh was part of one of such mahajanapadas, the ancient kingdom of Anga, which flourished in the 6th century BCE. Mahasthangarh, the oldest archaeological site in Bangladesh dating back to 600.

Linguistically, the oldest population of this land may have been speakers of Dravidian languages, such as the Kurux, or perhaps of Austroasiatic languages such as the Santals. Subsequently, people speaking languages from other language families, such as Tibeto-Burman, settled in Bengal. Indic Bengali represents the latest settlement.

While western Bangladesh, as part of Magadha, became part of the Indo-Aryan civilization by the 7th century BCE, the Nanda Dynasty was the first historical state to unify all of Bangladesh under Indo-Aryan rule. Later after the rise of Buddhism many missionaries settled in the land to spread the religion and established many monuments such as Mahasthangarh
