Pakistan is situated in the western part of the Indian subcontinent, with Afghanistan and Iran on the west, India on the east, and the Arabian Sea on the south. The name Pakistan is derived from the Urdu words Pak (meaning pure) and stan (meaning country).
Pakistan was one of the two original successor states to British India, which was partitioned along religious lines in 1947. For almost 25 years following independence, it consisted of two separate regions, East and West Pakistan, but now it is made up only of the western sector. Both India and Pakistan have laid claim to the Kashmir region; this territorial dispute led to war in 1949, 1965, 1971, 1999, and remains unresolved today.
