The war marked the end of the era of the Russo-Persian Wars, with Russia now the unquestioned dominant power in the Caucasus. Persia (Iran) was forced to cede swaths of territories that it never regained. The conquered territories spent more than 160 years under Russian domination before establishing their independence, except Dagestan, which is still a Russian possession. In 1991, through the dissolution of the USSR, the modern states of Georgia, Azerbaijan, and Armenia were established from the bulk of the South Caucasus territories that had come under the dominion of Russia by 1828.
