Delhi Sultanate — Study Notes
Overview
The Delhi Sultanate (1206–1526 CE) marks a transformative period in Indian history when five successive Turkish and Afghan dynasties ruled from Delhi. For the UPSSSC PET, this topic is critical because it bridges ancient India and the Mughal era, and questions frequently test dynasty sequences, key rulers, administrative innovations like the iqta system, and military campaigns. You must master the chronological order of dynasties—Slave (Mamluk), Khilji, Tughlaq, Sayyid, and Lodi—and understand their unique contributions and failures.
The Sultanate introduced new administrative practices, Persian as the court language, Indo-Islamic architecture (Qutub Minar, Alai Darwaza), and complex agrarian revenue systems. The iqta system, a form of land assignment to nobles in lieu of salary, became the backbone of military and revenue administration. The period also witnessed resistance from Rajput kingdoms, the Mongol invasions, and eventual consolidation of power that set the stage for Babur's conquest in 1526.
Questions range from direct factual recall (founder of a dynasty, capital shifts) to analytical ones (impact of iqta, reasons for Sultanate decline). Understanding administrative terms, military campaigns, and architectural landmarks will help you score confidently in the history section.

Key Concepts
- **Five Dynasties in Sequence**: Slave/Mamluk (1206–1290), Khilji (1290–1320), Tughlaq (1320–1414), Sayyid (1414–1451), Lodi (1451–1526). Remembering this sequence is non-negotiable.
- **Iqta System**: Land assignments (iqtas) given to military commanders (muqtis/iqtadars) instead of cash salaries. The iqtadar collected revenue from assigned territory, maintained troops, and sent surplus to the Sultan's treasury. Not hereditary initially; Firoz Shah Tughlaq made it hereditary, weakening central control.
- **Mongol Threat**: Repeated Mongol invasions (Chengiz Khan's raids, later Timur's sack of Delhi in 1398) forced Sultans to maintain large standing armies and fortify frontiers, draining resources and shaping military policy.
- **Revenue Reforms**: Alauddin Khilji's price control (market regulations) and Ghiyasuddin Tughlaq's revenue surveys attempted to stabilize the economy. Muhammad bin Tughlaq's token currency experiment (brass coins replacing silver) failed due to mass counterfeiting.
- **Decentralization Under Tughlaqs**: Muhammad Tughlaq's capital shift to Daulatabad (1327) and his erratic policies weakened Delhi's control. Provincial governors declared independence, leading to rise of Bahmani, Vijayanagar, Bengal, and Jaunpur sultanates.
- **Indo-Islamic Culture**: Persian literature flourished; Amir Khusro blended Indian and Persian music/poetry. Architecture fused Indian craftsmanship with Islamic domes, arches, and calligraphy—Qutub Minar, Alai Darwaza, Tughlaqabad Fort.
