Harshavardhana (r. 606–647 CE)
Of the Pushyabhuti (Vardhana) dynasty, ruling from Kanauj (Kannauj), Harsha is conventionally treated as the last major pan-north-Indian ruler before centuries of regional fragmentation. He came to the throne after the assassination of his brother-in-law, unified much of north India through a mix of conquest and alliance, but was checked in the south by Pulakeshin II of the Chalukyas of Badami at the Battle of the Narmada — a rare instance of a powerful northern king failing to subdue a southern rival, and a favourite exam pairing ("who defeated Harshavardhana?").
- His court poet Banabhatta wrote the Harshacharita, a biographical eulogy (and an important early prose work in Sanskrit literature) — do not confuse it with the Allahabad Prashasti (Samudragupta) or Aihole inscription (Pulakeshin II).
- Harsha himself is credited with authorship of three Sanskrit plays: Ratnavali, Priyadarshika, and Nagananda.
- He was visited by the Chinese Buddhist pilgrim-scholar Hiuen Tsang (Xuanzang), whose travel account (Si-Yu-Ki) is a vital contemporary source on Harsha's administration, the university at Nalanda, and the general state of Buddhism in India at the time.
- After Harsha's death without an heir, his empire fragmented rapidly — north India entered a long era with no single dominant power until the Delhi Sultanate.
The Tripartite Struggle for Kannauj (c. 8th–10th centuries)
With Kannauj now symbolising imperial legitimacy in north India (much as Rome or Constantinople did elsewhere), three powers fought a prolonged three-cornered contest for its control — one of the most commonly tested "which three powers fought for X" questions in the exam.
Memory hook — the three contestants: Pratihara, Pala, Rashtrakuta — "Please Pass the Rice" (P-P-R), one power from the west (Pratihara), one from the east (Pala), one from the south (Rashtrakuta) — visualise a triangle around Kannauj with each corner passing a dish inward.
Practice Recall: Name the three powers that fought over Kannauj, and the region each was based in, before reading on. (Answer: Gurjara-Pratiharas — Rajasthan/Malwa; Palas — Bengal/Bihar; Rashtrakutas — Deccan.)
| Power | Region/base | Notable ruler(s) | Notes |
|---|---|---|---|
| Gurjara-Pratiharas | Rajasthan/Malwa, later Kannauj itself | Nagabhata I (founder), Mihira Bhoja, Mahendrapala I | Eventually held Kannauj longest; renowned for repelling early Arab incursions into western India; built numerous temples (Khajuraho's earliest phase associated with a related Chandela dynasty under Pratihara suzerainty) |
| Palas | Bengal/Bihar | Gopala (founder, elected by regional chiefs to end anarchy — a rare recorded instance of "election" to kingship); Dharmapala, Devapala | Great patrons of Buddhism; founded/expanded Vikramashila University; extended influence into Southeast Asia's Buddhist networks |
| Rashtrakutas | Deccan (Manyakheta) | Dantidurga (founder), Krishna I (built the rock-cut Kailasa Temple at Ellora), Amoghavarsha I | Repeatedly raided north India and briefly held Kannauj; patronised Kannada and Apabhramsha literature; the Arab traveller Al-Masudi called the Rashtrakuta king one of the four great kings of the world |
No single power held Kannauj permanently; the contest steadily exhausted all three, leaving north India politically fragmented and militarily weakened — a factor historians cite among the reasons the region proved vulnerable to Turkish invasions from the 11th century onward.
