Regional Organizations in the Americas and Africa

The Organization for Security and Co-operation in Europe (OSCE) traces its origins to the Conference on Security and Co-operation in Europe (CSCE), a multilateral forum launched in 1973 that brought together, for the first time, states from both sides of the Cold War divide along with the United States and Canada. Its central achievement was the Helsinki Final Act, signed in August 1975 by thirty-five states, which established ten guiding principles for relations between states — including respect for sovereignty, the inviolability of frontiers, and human rights — in exchange for Western recognition of the post-war territorial status quo in Europe. The CSCE operated as a continuing diplomatic process rather than a formal organization for two decades. It was renamed the OSCE in 1995, acquiring permanent institutions such as a Secretariat in Vienna, and today counts 57 participating states, making it the world's largest regional security organization by membership, though it operates by consensus and lacks binding enforcement powers.
