The treaty united the two states, leaving Abkhazia as a "treaty republic" nominally subservient to Georgia. The special status of Abkhazia within Georgia was reinforced in the 1922 Georgian constitution, which mentioned the "special union treaty" between the two. The 1925 Abkhazian constitution noted it was united with Georgia "on the base of a special treaty". On 13 December 1922, while united with Georgia, Abkhazia joined the Transcaucasian Socialist Federative Soviet Republic (TSFSR), along with Armenia and Azerbaijan. This new federation was created ostensibly for economic purposes, but was more likely done to consolidate Soviet control over the region, which had been contentious. Abkhazia was mostly treated as an autonomous region of Georgia, though unlike other autonomous states in the Soviet Union, it had its own national symbols—a flag and coat of arms—and national army units, a right only given to full republics. The coat of arms was initially described in the 1925 constitution as being "composed of a golden hammer and sickle on the background of the Abkhazian landscape with inscription in the Abkhaz language 'SSR Abkhazia'". This was slightly modified in 1926, when the republican (and Soviet-wide) motto "Proletarians of all countries, unite!" was written in Abkhaz, Georgian, and Russian (previously it had only been written in Abkhaz). It also had its own constitution, created on 1 April 1925, another right only granted to full republics.
