In 1947-8 India and Pakistan fought their first war over Jammu and Kashmir. Under United Nations' supervision, they agreed to a ceasefire along a line which left one-third of the state - comprising what Pakistan calls Azad Jammu and Kashmir, and the Northern Areas administered by Pakistan and two-thirds, Jammu, Ladakh and the Kashmir Valley, controlled by India. In 1972, under the terms of the Simla agreement, the ceasefire line was renamed the Line of Control.
