The Delhi Sultanate Established

In 1206, following the conquests of Muhammad of Ghor, the Turkic general Qutb ud-Din Aibak established the Delhi Sultanate — the first of several Islamic dynasties to rule large portions of the Indian subcontinent from Delhi. Over the next 320 years, five successive dynasties (Mamluk, Khalji, Tughlaq, Sayyid, and Lodi) governed a realm that at its peak under the Tughlaqs encompassed most of the subcontinent. The Sultanate brought Persian administrative systems, Sufi mysticism, and Indo-Islamic architecture (the Qutb Minar, begun in 1193, remains Delhi's iconic monument). It also presided over periods of devastating destruction — Alauddin Khalji's conquests of Rajput kingdoms and the destruction of Nalanda University. Yet it fostered remarkable cultural synthesis: Amir Khusrau composed in both Persian and early Hindi, qawwali music emerged from Sufi traditions, and the Delhi Sultanate survived the Mongol invasions that destroyed much of the Islamic world.
