In 1968, Sheikh Mujibur Rahman was charged with sedition after the government of President Ayub Khan accused him for conspiring with India against the stability of Pakistan. While a conspiracy between Mujib and India for East Pakistan's secession was not itself conclusively proven, it is known that Mujib and the Awami League had held secret meetings with Indian government officials in 1962 and after the 1965 war. This case led to an uprising in East Pakistan which consisted of a series of mass demonstrations and sporadic conflicts between the government forces and protesters. In West Pakistan, Zulfikar Ali Bhutto, who served as foreign minister under President Ayub Khan, resigned from his office and founded the Pakistan Peoples Party (PPP) in 1967. The socialist political party took up opposition to President Ayub Khan as well.
