One-Page Rapid Revision Summary

The Turkish invasions began with Mahmud of Ghazni’s plundering raids and culminated in Muhammad of Ghur’s permanent conquest. While Ghazni’s campaigns targeted wealth, Ghur’s invasions aimed at political control, leading to the Delhi Sultanate’s foundation. Bihar became part of this expansion when Bakhtiyar Khilji destroyed Nalanda University and established Turkish authority in eastern India.
