Ancient Patna, known as Pataliputra, was the capital of the Magadha Empire under the Haryanka, Nanda, Mauryan, Shunga, Gupta and Pala empires. Pataliputra was a seat of learning and fine arts. Patliputra was home to many mathematicians, astronomers, astrologists and scholars including Gautam Buddha, Aryabhata, Panini, Vātsyāyana, Chanakya and Kālidāsa. Its population during the Maurya period (around 400 BCE) was about 400,000. Patna served as the seat of power, political and cultural centre of the Indian subcontinent. With the fall of Gupta Empire, Patna lost its glory. It was revived again in the 17th century by the British as a centre of international trade. The modern district of Patna was created in September 1770 as provincial council by the British, to supervise revenue matters of Bihar. In 1793, Patna became a separate judicial district. This led the foundation of modern district. The re-organization of the districts in the State took effect in 1972.
