The term "Delhi Sultan" refers to a series of Muslim rulers who governed the region of Delhi in northern India from the 13th to the 16th centuries. This period is marked by the establishment of the Delhi Sultanate, which played a significant role in the spread of Islam in the Indian subcontinent. The sultans were known for their military conquests, administrative reforms, and cultural contributions. The Delhi Sultanate comprised five major dynasties: the Mamluk, Khilji, Tughlaq, Sayyid, and Lodi dynasties. Each dynasty contributed to the political and cultural landscape of India, influencing architecture, language, and art. The era ended with the rise of the Mughal Empire, which further transformed the region's history.
