Georgia is a country located at the intersection of Eastern Europe and Western Asia. It is a part of the Caucasus region, bounded to the west by the Black Sea, to the north and east by Russia, to the south by Turkey and Armenia, and to the southeast by Azerbaijan. It covers 69,700 square kilometres, and has a population of around 4 million. Georgia is a representative democracy governed as a unitary parliamentary republic. Tbilisi is the capital and largest city, home to roughly a quarter of the population.
During the classical era, several independent kingdoms became established in what is now Georgia, such as Colchis and Iberia. Georgians officially adopted Christianity in the early fourth century, which contributed to the spiritual and political unification of early Georgian states. In the Middle Ages, the unified Kingdom of Georgia emerged and reached its Golden Age during the reign of King David the Builder and Queen Tamar the Great 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 Ottoman Empire and successive dynasties of Persia.
