Located in the heart of Eurasia, Transcaucasia is made up of three countries: Azerbaijan, Armenia and Georgia.
The three kingdoms formed their own nation very early in history, and even established their own country at one time. However, due to its special geographical location, these three countries have been invaded by foreign tribes many times in history.
Several great powers have risen here, and in addition to the storms brought by the Mongol Conquest, Persia and the Ottomans have long fought for it. Of course, Russia, which rose later, was a hungry wolf.
After several great power rivalries, in the early 19th century, the northern part of Azerbaijan (the southern part belonged to Iran and Turkey) was occupied by Russia.
Historically, Armenia was once an independent kingdom, but it was divided between the Ottomans and Russia, with the Ottomans occupying Western Armenia and Persia annexing Eastern Armenia. However, in the early 19th century, Russia took over Eastern Armenia after winning the war against Iran.
Georgia, once the largest country in transcaucasia during its power, was soon hit in the same way, and in the early 19th century Georgia was annexed by Russia.
It can be said that whether it was annexed by the Ottomans or occupied by Russia, there was almost no possibility of independence, but the Transcaucasia encountered a good opportunity, that is, the First World War.
During world war I, the Russian backyard caught fire and overthrew the Tsar, which was a huge blow to Russia, and the territory that had been expanding for hundreds of years could not be saved at once. Independence movements have been set off in many places. Transcaucasia is of course no exception, with the establishment of the "Transcaucasian Democratic Federal Republic". At the same time, the Soviets in the Caucasus were developing rapidly.
This newly formed state was not Soviet power, but for historical reasons, the ethnic complex and contradictory it was soon divided into three countries.
Independence and independence, like those countries in Eastern Europe that were once annexed by Russia, are not only full of historical and ethnic entanglements, but still face competition for great powers.
So there are those who are moving closer to the West, and there are those who are holding the thighs of Soviet Russia. These three countries themselves also have many historical problems such as territorial issues.
As a result, not long after independence, the Soviet forces in the three countries, with the support of Soviet Russia, overthrew the original power and established Soviet power. And once again came together to form the Transcaucasian Soviet Socialist Federative Republic, which joined the Union of Soviet Socialist Republics (USSR).
