Meanwhile internal disagreements in the TDFR led to Georgia leaving the federation in May 1918, followed shortly thereafter by Armenia and Azerbaijan. Georgian and Abkhaz officials met in an attempt to hammer out a deal, with Georgia pushing to include Abkhazia within Georgia but as an autonomous region, however many Abkhaz leaders feared that Georgia aimed to 'Georgian-ise' the region and annex it outright. Russia recognised the independence of Georgia via the Treaty of Moscow (1920). Meanwhile disputes between Abkhaz and Georgian officials continued, however these were rendered moot when in 1920 Russia's Red Army invaded Georgia in 1921. Abkhazia was designated as the Socialist Soviet Republic of Abkhazia, on the proviso that it would later join the Georgian Soviet Socialist Republic under a 'special union treaty'. Georgia was later incorporated along with Armenia and Azerbaijan in the Transcaucasian SFSR within the USSR. The Georgian SSR was reconstituted in 1936, incorporating Abkhazia as the (downgraded) Abkhaz Autonomous Soviet Socialist Republic.
