Pakistan-occupied Kashmir (PoK) refers to the portion of the former princely state of Jammu and Kashmir that is currently under Pakistani control. The territory has been a source of tension between India and Pakistan since the two countries gained independence in 1947, and the disputed status of PoK has been a key issue in the ongoing conflict between the two nations. The disputed territory was ruled by Maharaja Hari Singh, a Hindu king, but the region had a majority Muslim population. When the state of Jammu and Kashmir acceded to India in 1947, Pakistan claimed that the accession was invalid and sent troops into the region.
