The Commonwealth of Independent States (CIS) is a regional organization formed in 1991 after the dissolution of the Soviet Union, consisting of several former Soviet republics. It was established to promote cooperation in political, economic, and cultural matters among its member states while allowing them to maintain their sovereignty. The CIS emerged during the end of the Cold War, symbolizing a shift in the post-Soviet landscape as these countries sought to redefine their relationships with one another and the world.
