The Commonwealth of Independent States (CIS) was formed in 1991 when Russia, Ukraine, Belarus, Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan and Armenia secretly met and decided to dissolve the Soviet Union. The CIS Charter established that the member states would be independent and equal subjects under international law. The objectives of the CIS are to ensure international peace, strengthen cooperation among members economically and culturally, and protect human rights. Nine of the fifteen former Soviet republics originally joined the CIS, though some have since withdrawn. The headquarters is located in Minsk, Belarus.
