The Karachi Agreement of 1949 was signed by the military representatives of India and Pakistan, supervised by the United Nations Commission for India and Pakistan, establishing a cease-fire line in Kashmir following the Indo-Pakistani War of 1947. It established a cease-fire line which has been monitored by United Nations observers from the United Nations since then. Background The Security Council Resolution 39 of April 1948 established a UN Commission (United Nations Commission for India and Pakistan — UNCIP) to mediate between India and Pakistan to bring about a cessation of fighting in Kashmir and to make arrangements for a popular plebiscite.
