Commonwealth of Independent States
The Soviet Union had 15 republics: Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine, Uzbekistan, Georgia, Estonia, Latvia, and Lithuania. On 6th September 1991, the Soviet Union had recognized the independence of Estonia, Latvia, and Lithuania. Out of the remaining 12 republics, all (except Georgia) joined the CIS. Before joining the CIS, on 21st December 1991, leaders of these 11 countries had met in Kazakhstan to accept the original CIS agreement of 8th December 1991. Because Ukraine did not ratify the CIS agreement in the national parliament, it never became an official member of the CIS, but nevertheless participated as a de facto member. In December 1993, Georgia also joined the CIS. On 26th August 2006 Turkmenistan left the permanent membership, and became an associate member. On 15th August 2008 Georgia left the CIS membership, and Georgia's CIS membership officially ended on 17th August 2009. On 19 May 2018, Ukraine, which stopped participating in CIS in 2014 because of its conflict with Russia over Crimea and the Donbas, formally ended all participation in CIS.
