Gupta Empire

c. 240 CE – c. 579 CE · about 339 years approximate dates

The Gupta Empire, which became an imperial power under Chandragupta I in the early 4th century, ruled much of northern India and is often called a classical age of Indian civilisation, with advances in mathematics, astronomy and Sanskrit literature. It declined under Hephthalite invasions in the late 5th and 6th centuries.
