Because for the first time a foreign power came not only to raid India but to rule part of it — and yet the rest of Indian life carried on largely as before. The chapter’s own words: “Like every transitional period, this one saw both change and continuity.”
Two examples of change.
- Raiding became ruling. Mahmūd of Ghazni made 17 campaigns and went home each time; he “did not attempt to establish a permanent base in India beyond Punjab”. Muhammad Ghūrī, after the Second Battle of Tarain in 1192, captured Delhi and “sought territorial conquest”, leaving Qutb-ud-din Aibak behind to hold it — “the start of foreign rule in parts of north India”.
- Great centres of learning were destroyed. Bakhtiyār Khiljī destroyed Nālandā and Vikramaśhilā. Historians of Buddhism agree that this “precipitated the decline of Buddhism in India”. This change was permanent: those universities never reopened.
Two examples of continuity.
- Trade never stopped. “India’s trade with China and Southeast Asia kept growing during this period,” and the merchant guilds “survived and adapted”. Agriculture remained the mainstay of the economy throughout.
- Building and learning went on. The Hoysala temples at Belur and Halebidu, Khajuraho’s Kandāriyā Mahādeva temple, the Warangal fort, the Puri Jagannātha temple — and Bhāskarāchārya’s Līlāvatī (1150) and Someśhvara III’s Mānasollāsa — all belong to these same two centuries.
