Georgian culture evolved over thousands of years from its foundations in the Iberian and Colchian civilizations. Georgian culture enjoyed a renaissance and golden age of classical literature, arts, philosophy, architecture and science in the 11th century. Georgian culture was influenced by Classical Greece, the Roman Empire, the Byzantine Empire, the various Iranian empires (notably the Achaemenid, Parthian, Sassanian, Safavid and Qajar empires), and later, from the 19th century, by the Russian Empire.
