The full form of LOC is Line of Control.
The Line of Control (LOC) is a military control line between the Indian and Pakistani controlled parts of the former princely state of Jammu and Kashmir. It is not an internationally recognized border, but serves as the de facto border. It divides Kashmir into two parts: Azad Kashmir, controlled by Pakistan, and Jammu and Kashmir, controlled by India. The LOC was established after the Indo-Pakistani War of 1947-1948 and was formalized in the Shimla Agreement of 1972.
