The United Nations has undergone phases of reform since its foundation in 1945. During the first years, the first decisive change was the development of peacekeeping measures to oversee the implementation of ceasefire agreements in 1949 in the Middle East and one year later in the Kashmir conflict between India and Pakistan. The Soviet Union launched reform initiatives during the East-West antagonism in the 1950s to curtail the independence of the Secretariat by replacing the post of Secretary-General with a troika, including a representative from the socialist states. Decolonization created rapid growth in UN membership, and by 1965 it stood at 118, twice as much as at the Organization's founding.
