Gupta dynasty, rulers of the Magadha (now Bihar) state in northeastern India. They maintained an empire over northern and parts of central and western India from the early 4th to the late 6th century ce. Historians once regarded the Gupta period as the classical age of India—during which the norms of Indian literature, art, architecture, and philosophy were established—but many of those assumptions have been challenged by more extensive studies of Indian society and culture between the Mauryan and Gupta periods. Among the products traditionally thought to be from the Gupta era were the decimal system of notation, the great Sanskrit epics, and Hindu art, along with contributions to the sciences of astronomy, mathematics, and metallurgy.
Administratively, the Gupta kingdom was divided into provinces, and these in turn were divided into smaller units called pradeshas or vishayas. The provinces were governed by high imperial officers or members of the royal family. A decentralized system of authority is indicated by the composition of Gupta-era municipal boards.
The first ruler of the empire was Chandra Gupta I, who united the Guptas with the Licchavis by marriage. His son, the celebrated Samudra Gupta, expanded the empire through conquest. It would seem that his campaigns extended Gupta power in northern and eastern India and virtually eliminated the oligarchies and the minor kings of central India and the Ganges valley, regions which then came under the direct administrative control of the Guptas. The empire’s third ruler, Chandra Gupta II (or Vikramaditya, “Sun of Valour”), was celebrated for extending the empire to Ujjain, but his reign became more associated with cultural and intellectual achievements than with military conquest. His successors—Kumara Gupta, Skanda Gupta, and others—saw the gradual demise of the empire with the invasion of the Hunas (a branch of the Hephthalites). By the mid-6th century, when the dynasty apparently came to an end, the kingdom had dwindled to a small size.
