For a long time the city and country was the central seat of the dualistic Zoroastrian religion, the founder of which, Zoroaster, died within the walls according to the Persian poet Firdowsi. Armenian sources state that the Arsacid Dynasty of the Parthian Empire established its capital in Balkh. There is a long-standing tradition that an ancient shrine of Anahita was to be found here, a temple so rich it invited plunder. Alexander the Great married Roxana of Bactria after killing the king of Balkh. The city was the capital of the Greco-Bactrian Kingdom and was besieged for three years by the Seleucid Empire (208–206 BC). After the demise of the Greco-Bactrian kingdom, it was ruled by Indo-Scythians, Parthians, Indo-Parthians, Kushan Empire, Indo-Sassanids, Kidarites, Hephthalite Empire and Sassanid Persians before the arrival of the Arabs.
