The Kashmir conflict is a territorial conflict primarily between India and Pakistan over the Kashmir region. The conflict started after the partition of India in 1947 as a dispute over the former princely state of Jammu and Kashmir and escalated into three wars between India and Pakistan and several other armed skirmishes. China has also been involved in the conflict in a third-party role. Both India and Pakistan claimed the entirety of the former princely state of Jammu and Kashmir, although Pakistan has recognized Chinese sovereignty over the Trans-Karakoram Tract and Aksai Chin since 1963. India controls approximately 55% of the land area of the region and 70% of its population, Pakistan controls approximately 30% of the land, while China controls the remaining 15%. India administers Jammu, the Kashmir Valley, Ladakh, and the Siachen Glacier. Pakistan administers Azad Kashmir and Gilgit-Baltistan. China administers the Aksai Chin region and the mostly uninhabited Trans-Karakoram Tract.
