Introduction

The Delhi Sultanate (1206–1526 CE) was one of the most significant political powers in medieval Indian history. For more than three centuries, it ruled large parts of the Indian subcontinent from its capital at Delhi, laying the foundations for major political, administrative, economic, and cultural transformations. Established by Muslim rulers of Turkic and Afghan origin, the Sultanate introduced new systems of governance, military organization, architecture, trade, and cultural exchange that profoundly influenced the course of Indian history.

The Delhi Sultanate was not a single dynasty but a succession of five ruling dynasties:

• The Mamluk (Slave) Dynasty (1206–1290)
• The Khalji Dynasty (1290–1320)
• The Tughlaq Dynasty (1320–1414)
• The Sayyid Dynasty (1414–1451)
• The Lodi Dynasty (1451–1526)

Each dynasty contributed in different ways to the political and cultural development of medieval India. The period ended in 1526, when Babur defeated Ibrahim Lodi in the First Battle of Panipat, leading to the establishment of the Mughal Empire.

Historical Background

The origins of the Delhi Sultanate can be traced to the invasions of Muhammad of Ghor during the late twelfth century.

In 1192, Muhammad of Ghor defeated the Rajput king Prithviraj Chauhan in the Second Battle of Tarain, gaining control over much of northern India.

Although Muhammad of Ghor did not establish a permanent empire in India, his military commander Qutb-ud-din Aibak consolidated these territories. After Muhammad’s death in 1206, Aibak declared himself Sultan, marking the beginning of the Delhi Sultanate.
