What was the international organization dismantled in 1977?

The international organization dismantled in 1977 was the United Nations Emergency Force (UNEF). Established in 1956 to help maintain peace during the Suez Crisis, UNEF played a critical role in stabilizing the region. Its mandate ended in 1973 after the Yom Kippur War, and it was officially disbanded in 1977 as peacekeeping needs evolved and were addressed through different mechanisms.
