The flag of the Transcaucasian Socialist Federative Soviet Republic (TSFSR). The star is often thought to symbolize the five fingers of the worker’s hand. Inside of the star is the hammer and sickle symbol, which portray a unified working class (agricultural and industrial combined). The letters on the flag are the abbreviation for the name of the republic in Cyrillic.

Transcausasian Socialist Federative Soviet Republic

In 1922 the leaders of the Azerbaijan Soviet Socialist Republic (SSR), along with the Georgian SSR and Armenian SSR, formed the Transcaucasian Socialist Federative Soviet Republic (TSFSR), a regional republic subordinate to central Soviet government. This arrangement lasted until 1936, when the government of the Soviet Union signed a new Constitution, reorganizing its administration. The three nations became individual Soviet Socialist Republics once more.
