Collective Security Treaty Organization

The Collective Security Treaty Organization (CSTO; Russian: Организация Договора о коллективной безопасности (ОДКБ), romanized: Organizatsiya dogovora o kollektivnoy bezopasnosti, ODKB) 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.
