United Nations Security Council
Along with the five permanent members, the Security Council of the United Nations has temporary members that hold their seats on a rotating basis by geographic region. Non-permanent members may be involved in global security briefings. In its first two decades, the Security Council had six non-permanent members, the first of which were Australia, Brazil, Egypt, Mexico, the Netherlands, and Poland. In 1965, the number of non-permanent members was expanded to ten.

Seats on the Council are based on geographical representation with 14 allocated to African states, 11 to Asia-Pacific states, 6 to East European states, 10 to Latin American and Caribbean states and 13 to West European and other states.
