Ayub Khan ruled Pakistan from 1958-1969 and introduced economic and political reforms. He encouraged private industry and agriculture, leading to strong economic growth. However, his "Basic Democracy" system was criticized as authoritarian. In 1965, war broke out with India over Kashmir. After 17 days of fighting, the Tashkent Declaration established a ceasefire but was unpopular in Pakistan for failing to resolve Kashmir. Growing public discontent over the war and Ayub's attempts to install his son as successor led to his resignation in 1969.
