Answer
Ayub Khan, the second president of Pakistan, passed away in 1974. He had a significant impact on Pakistan's history, serving as president from 1958 to 1969. During his presidency, he implemented various economic and political reforms, including the introduction of a new constitution in 1962. However, his authoritarian rule and the country's involvement in the 1965 war with India led to widespread dissatisfaction, culminating in his resignation in 1969.
