Kashmir, a Himalayan region situated at the northernmost point of the Indian subcontinent, was governed as an autonomous princely state known as Jammu and Kashmir in the British Raj prior to the Partition of India in August 1947. Following the independence of India and Pakistan post-partition, the region became the subject of a major territorial dispute that has hindered their bilateral relations. The two states have engaged each other in two large-scale wars over the region in 1947–1948 and 1965. India and Pakistan have also fought smaller-scale protracted conflicts over the region in 1984 and 1999. Approximately 45.1% of the Kashmir region is controlled by India (administratively split into Jammu and Kashmir and Ladakh), which also claims the entire territory of the former princely state of Jammu and Kashmir that is not under its control. India's control over Jammu and Kashmir and Ladakh as well as its claim to the rest of the region has likewise been contested by Pakistan, which controls approximately 38.2% of the region (administratively split into Azad Jammu and Kashmir and Gilgit−Baltistan) and claims all of the territory under Indian control. Additionally, approximately 20% of the region has been controlled by China (known as Aksai Chin and the Shaksgam Valley) since the Sino-Indian War of 1962 and the Sino-Pakistani Agreement of 1963. The Chinese-controlled areas of Kashmir remain subject to an Indian territorial claim, but are not claimed by Pakistan.
