The National Awami Party (NAP) was the major progressive political party in East and West Pakistan. It was founded in 1957 in Dhaka, erstwhile East Pakistan, by Abdul Hamid Khan Bhashani and Yar Mohammad Khan, through the merger of various leftist and progressive political groups in Pakistan. Commonly known as the NAP, it was a major opposition party to Pakistani military regimes for much of the late 1950s and mid 1960s. In 1967 the party split into two factions, one in East Pakistan and another in West Pakistan.
