As a result, East Pakistan became independent and Bangladesh was established. After India and Pakistan became independent, Pakistan was divided into east and west parts by India, and the regime was always in the hands of Western Pakistan people. In 1971, as East Pakistan's tendency towards autonomy became increasingly obvious, Pakistan dictator Yahya Khan sent troops to Dhaka, the capital of East Pakistan, and arrested Sheikh Mujib Rahman, leader of the East Pakistan People's League. Pakistan's autonomy fled to India and received support from India in terms of weapons and training. Yahya Khan accused India of interfering in Pakistan's internal affairs and first attacked India on December 3, 1971. The India-Pakistan War broke out. Since Yahya Khan had issued a war warning before launching the attack, the Indian army was relatively well prepared for the war and invaded East Pakistan the next day. On December 6, the Indian government announced its recognition of Bangladesh's independence. On December 16, India occupied Dhaka, the capital of East Pakistan.
