Because in these two centuries the political map of north India begins to change hands — foreign rule starts in parts of it — while everything else in Indian life carries on. A transition is not a clean break. The chapter’s own summing-up in ‘Taking Stock’ says it exactly: “Like every transitional period, this one saw both change and continuity.”
What changed.
- Invasions went deeper than before. The Arabs of the previous chapter made “repeated attempts” and their incursions “had little overall impact on India”. Now “invasions by Turkic powers penetrated much deeper into north India, despite stubborn resistance from native kingdoms.”
- Raiding turned into ruling. Mahmūd of Ghazni conducted 17 campaigns and went home each time with booty; he “did not attempt to establish a permanent base in India beyond Punjab”. Muhammad Ghūrī, a century and a half later, was different — “unlike Mahmūd, who merely plundered and withdrew, he sought territorial conquest”. He left behind his general Qutb-ud-din Aibak, who later founded the Delhi Sultanate.
- A new creed entered the religious landscape. The chapter calls this “the spread of Islam as a new creed in India’s religious landscape”.
- Centres of learning were destroyed. Bakhtiyār Khiljī destroyed Nālandā and Vikramaśhilā. “There is a consensus among historians of Buddhism that this destruction of its large centres of learning precipitated the decline of Buddhism in India, although a few other factors may have also played a role.”
- One administrative change. Muhammad Ghūrī’s system was “more centralised” and “granted temporary land assignments to officers in return for revenue collection and military service”.
What did not change.
- Most of India was never touched. “Large parts of northern India and all of south India remained outside the hold of the Turkic invaders.”
- Trade kept growing. “Despite the political disturbances we have seen, India’s trade with China and Southeast Asia kept growing during this period,” and “the merchant guilds survived and adapted”.
- Building and writing never stopped. Khajuraho, Belur, Halebidu, Warangal, Thanjavur, Gangaikoṇḍacholapuram, Puri — all belong to these very centuries; so do the Līlāvatī, the Mānasollāsa, the Gītagovindam and Basavaṇṇa’s vachanas.
