The Delhi Sultanate
Overview
The Delhi Sultanate (1206–1526 CE) refers to five successive Muslim dynasties that ruled from Delhi: the Slave (Mamluk) dynasty, the Khalji dynasty, the Tughlaq dynasty, the Sayyid dynasty, and the Lodi dynasty. The Sultanate marked the establishment of Muslim rule in North India and brought new administrative systems, architectural styles, and cultural influences. The period ended with the Mughal invasion under Babur at the First Battle of Panipat (1526).

Summary
The Delhi Sultanate was a period of transition and consolidation. New administrative ideas (the Iqta system), architectural forms (the mosque, the minar, the dome), and social patterns (the Persianised court culture) were introduced to India. The period also saw repeated Mongol invasions and the terrible sack of Delhi by Timur. The Sultanate collapsed in 1526 when the Lodi dynasty fell to Babur at Panipat. For ICSE students, the Sultanate period is critical for understanding the political and cultural foundations of medieval India.
