The territory that now constitutes Tajikistan was previously home to several ancient cultures, including the city of Sarazm of the Neolithic and the Bronze Age and was later home to kingdoms ruled by people of different faiths and cultures, including the Oxus Valley Civilisation, Andronovo Culture, Buddhism, Nestorian Christianity, Hinduism, Zoroastrianism, Manichaeism and Islam. The area has been ruled by numerous empires and dynasties, including the Achaemenid Empire, Sasanian Empire, Hephthalite Empire, Samanid Empire and the Mongol Empire. After being ruled by the Timurid dynasty and the Khanate of Bukhara, the Timurid Renaissance flourished. The region was later conquered by the Russian Empire and subsequently by the Soviet Union. Within the Soviet Union, the country's modern borders were drawn when it was part of Uzbekistan as an autonomous republic before becoming a full-fledged Soviet republic in 1929.
