who became the first sultan of newly established muslim sultanate of delhi in 1207
Delhi Sultanate Qutb al-Din Aibak, a former Turkic Mamluk slave of Muhammad Ghori, was the first sultan of Delhi, and his Mamluk dynasty conquered large areas of northern India. Afterwards, the Khalji dynasty was also able to conquer most of central India, but both failed to conquer the whole of the Indian subcontinent. The sultanate reached the peak of its geographical reach during the Tughlaq dynasty, occupying most of the Indian subcontinent.[10] This was followed by decline due to Hindu reconquests, states such as the Vijayanagara Empire asserting independence, and new Muslim sultanates such as the Bengal Sultanate breaking off.[11][12]
History of Delhi The third and greatest Mughal emperor, Akbar, moved the capital to Agra, resulting in a decline in the fortunes of Delhi. In the mid-17th century, the Mughal Emperor Shah Jahan (1628–1658) built the city that sometimes bears his name Shahjahanabad, the seventh city of Delhi that is more commonly known as the old city or old Delhi. This city contains a number of significant architectural features, including the Red Fort (Lal Qila) and the Jama Masjid. The old city served as the capital of the later Mughal Empire from 1638 onwards, when Shah Jahan transferred the capital back from Agra. Aurangzeb (1658–1707) crowned himself as emperor in Delhi in 1658 at the Shalimar garden ('Aizzabad-Bagh) with a second coronation in 1659. After 1680, the Mughal Empire's influence declined rapidly as the Hindu Maratha Empire rose to prominence.[24]
