Gupta Empire

The Gupta Empire presided over what historians call the 'Golden Age' of Indian civilization — a period of extraordinary achievement in mathematics, astronomy, literature, art, and philosophy. Chandragupta I (r. ~320-335 CE) established the dynasty through a strategic marriage alliance with the Lichchhavi princess Kumaradevi, gaining legitimacy and territory in the Gangetic heartland. His son Samudragupta (r. ~335-375 CE) was among India's most accomplished military commanders, with the Prayaga Prashasti (composed by the court poet Harishena) recording his conquest of nearly the entire subcontinent. Chandragupta II, identified by many scholars with the legendary Vikramaditya, extended Gupta power to its maximum territorial extent and patronized a court that included Kalidasa (widely regarded as Sanskrit literature's greatest poet), the astronomer-mathematician Aryabhata, and the polymath Varahamihira. It was during the Gupta period that Aryabhata calculated the Earth's circumference to remarkable accuracy, proposed a heliocentric model, and articulated the concept of zero as a mathematical placeholder. Nalanda University, though predating the Guptas, reached its zenith as an international center of Buddhist and secular learning under Gupta patronage. The temple architecture of this period — particularly the Dashavatara Temple at Deogarh — established the formal vocabulary of Hindu temple design. Fa-Xian, the Chinese Buddhist pilgrim who visited India during Chandragupta II's reign, described a prosperous and well-governed empire. The Gupta Empire declined in the 5th-6th centuries under pressure from Hunic invasions, fragmenting into regional successor states.
