What is the Delhi Sultanate?

The Delhi Sultanate (1206–1526 CE) was the first major Islamic political entity to rule over large parts of the Indian subcontinent, with its capital at Delhi. It was established in 1206 when Qutb ud-Din Aibak, a Turkic Mamluk (slave-soldier) general of Muhammad of Ghor, declared independence after his master's assassination and became the first Sultan of Delhi.

Over its 320-year history, the Sultanate was ruled by five successive dynasties: the Mamluk (Slave), Khalji, Tughlaq, Sayyid, and Lodi. It introduced significant changes to Indian administration, architecture, language, and culture, and served as the precursor to the Mughal Empire.
