Collective Security Treaty Organisation

The Collective Security Treaty Organization is an intergovernmental military alliance in Eurasia consisting of six post-Soviet states: Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan. The Collective Security Treaty has its origins in the Soviet Armed Forces, which was replaced in 1992 by the United Armed Forces of the Commonwealth of Independent States, and was then itself replaced by the successor armed forces of the respective independent states. Former members of the CSTO military alliance were Azerbaijan, Georgia and Uzbekistan.
