North Indian empire whose era saw a flowering of Sanskrit literature, Hindu temple art, astronomy and mathematics.

Chandragupta I founded it around AD 320 in the old Mauryan heartland of Magadha; his son Samudragupta and grandson Chandragupta II extended it across northern India. The court patronized the poet Kalidasa, and the astronomer Aryabhata (born 476) calculated pi to four decimals and argued that Earth spins. Decimal place-value numerals, ancestors of today's digits, took shape in this era, and Hindu traditions took classical form. Hun invasions weakened the empire, which faded by about 550.
Why it matters
Its numerals, passed west by Arab scholars, became the 'Arabic' numbers used worldwide, and its art and literature became the classical standard of Indian culture.
How we know
Inscriptions like Samudragupta's on the Allahabad pillar, gold coins, Aryabhata's surviving book, Udayagiri's cave temples, and the Chinese pilgrim Faxian's account of his travels around 400–411.
Still debated
Whether it was truly a 'golden age', or a label exaggerated by colonial-era and nationalist historians, is debated.
Connections (3)
▸Gupta Empire: India's classical golden age reunited northern India for the first time since Maurya EmpireMostly agreed
The connection
After the Mauryas fell around 185 BC, northern India was divided among regional dynasties and Central Asian invaders such as the Kushans. The Guptas rose in the same Magadha heartland around Pataliputra, and by about 400 controlled most of the north, the largest Indian empire since the Mauryas, though looser in structure.
When and how
Magadha and the Ganges plain, c. AD 320–415; Chandragupta I, Samudragupta and Chandragupta II.
How sure are we?
Samudragupta's victory list is carved on the same Allahabad pillar that bears Ashoka's edicts; coins and inscriptions map Gupta rule.
Debates and open questions
Whether the Guptas consciously modeled themselves on the Mauryas is unclear; the founder's name, Chandragupta, echoes the Maurya founder's.
▸Gupta Empire: India's classical golden age developed the decimal numerals passed on by Islamic Golden Age (Baghdad's House of Wisdom)Mostly agreed
The connection
Indian mathematicians developed place-value numerals with nine digits and a symbol for zero; Aryabhata (499) and Brahmagupta (628) worked with them. Indian astronomy texts were translated in Baghdad in the 770s, and al-Khwarizmi wrote a book on 'Indian reckoning' around 825. Through its Latin translation, Europe learned what it calls 'Arabic numerals'.
When and how
India, about 400–700, during and after the Gupta era; Baghdad, 770s–820s; key transmitters were the astronomer al-Fazari and al-Khwarizmi.
How sure are we?
Indian inscriptions with place-value numbers; Arabic texts calling the numerals 'Hindu'; the Latin 'Algoritmi de numero Indorum', which gave us the word algorithm.
Debates and open questions
When zero became a true number is debated; the Bakhshali manuscript's leaves carbon-date from about 200 to 1000, and credit to the Gupta era itself is partly a matter of timing.
▸Gupta Empire: India's classical golden age built early Hindu temples, a tradition echoed at Khmer Empire and Angkor WatMostly agreed
The connection
Gupta-era India produced some of the first stone Hindu temples, with a sanctuary for the god's image and, later, towers symbolizing Mount Meru. Indian traders and priests carried Hindu and Buddhist ideas, Sanskrit and temple design to Southeast Asia. Khmer kings adopted Sanskrit titles and god-king rituals, and Angkor Wat's towers echo the same sacred-mountain idea.
When and how
India, about 400–600; Southeast Asia from the 400s onward, through the Funan and Chenla states that came before Angkor.
How sure are we?
Sanskrit inscriptions in Cambodia from the 600s onward; shared temple layouts and imagery; scenes from Indian epics like the Ramayana carved at Angkor Wat.
Debates and open questions
How the ideas traveled is debated: did Indian settlers bring them, or did local rulers pick and adapt Indian forms? Most scholars now stress local choice.
