who was the first muslim king of india
Islamic rulers in the Indian subcontinent During the last quarter of the 12th century, Muhammad of Ghor invaded the Indo-Gangetic plain, conquering in succession Ghazni, Multan, Sindh, Lahore, and Delhi. Qutb-ud-din Aybak, one of his generals proclaimed himself Sultan of Delhi. In the 13th century, Shamsuddīn Iltutmish (1211–1236), a former slave-warrior, established a Turkic kingdom in Delhi, which enabled future sultans to push in every direction; within the next 100 years, the Delhi Sultanate extended its way east to Bengal and south to the Deccan, while the sultanate itself experienced repeated threats from the northwest and internal revolts from displeased, independent-minded nobles. The sultanate was in constant flux as five dynasties, all of either Turkic or Afghan origin,[3] rose and fell: the Slave dynasty (1206–90), Khalji dynasty (1290–1320), Tughlaq dynasty (1320–1413), Sayyid dynasty (1414–51), and Lodi dynasty (1451–1526). The Khalji dynasty, under 'Alā'uddīn (1296–1316), succeeded in bringing most of South India under its control for a time, although conquered areas broke away quickly. Power in Delhi was often gained by violence—nineteen of the thirty-five sultans were assassinated—and was legitimized by reward for tribal loyalty. Factional rivalries and court intrigues were as numerous as they were treacherous; territories controlled by the sultan expanded and shrank depending on his personality and fortunes.
