What was the main issue that divided people in South Asia?

There have been several main issues that have divided people in South Asia throughout history. One of the major issues is religious conflict, particularly between Hindus and Muslims. This conflict resulted in the partition of British India in 1947, creating the separate nations of India and Pakistan based on religious lines. The ongoing disputes between India and Pakistan over the region of Kashmir also contribute to the division in South Asia.

Other significant issues include ethnic and linguistic divides, caste-based discrimination, territorial disputes, economic disparities, and political conflicts. These divisions have often led to tensions, conflicts, and violence within the region.
