Georgia (??????????, ) is a transcontinental country at the intersection of Eastern Europe and Western Asia. It is part of the Caucasus region, bounded by the Black Sea to the west, Russia to the north and northeast, Turkey to the southwest, Armenia to the south, and by Azerbaijan to the southeast. The country covers an area of 69700 km2, and has a population of 3.7 million people. Tbilisi is its capital and largest city, home to roughly a third of the Georgian population.
During the classical era, several independent kingdoms became established in what is now Georgia, such as Colchis and Iberia. In the early 4th century, ethnic Georgians officially adopted Christianity, which contributed to the spiritual and political unification of the early Georgian states. In the Middle Ages, the unified Kingdom of Georgia emerged and reached its Golden Age during the reign of King David IV and Queen Tamar in the 12th and early 13th centuries. Thereafter, the kingdom declined and eventually disintegrated under the hegemony of various regional powers, including the Mongols, the Turks, and various dynasties of Persia. In 1783, one of the Georgian kingdoms entered into an alliance with the Russian Empire, which proceeded to annex the territory of modern Georgia in a piecemeal fashion throughout the 19th century.
