Ideas from British and American philosophy greatly shaped philosophical development in Pakistan. Analysts such as M. M. Sharif and Zafar Hassan established the first major Pakistani philosophical movement in 1947. After the 1971 war, philosophers such as Jalaludin Abdur Rahim, Gianchandani, and Malik Khalid incorporated Marxism into Pakistan's philosophical thinking. Influential work by Manzoor Ahmad, Jon Elia, Hasan Askari Rizvi, and Abdul Khaliq brought mainstream social, political, and analytical philosophy to the fore in academia. Works by Noam Chomsky have influenced philosophical ideas in various fields of social and political philosophy.
