Emblems of the Soviet Republics

The emblems of the constituent republics of the Union of Soviet Socialist Republics all featured predominantly the hammer and sickle and the red star that symbolized communism, as well as a rising sun (although in the case of the Latvian SSR, since the Baltic Sea is west of Latvia, it could be interpreted as a setting sun), surrounded by a wreath of wheat (except the Karelo-Finnish SSR with a wreath of rye). The USSR State motto, Workers of the world, unite! , in both the republic's language and Russian was also placed on each one of them.
