Hyderabad was founded by the Quṭb Shāhī sultans of Golconda, among whom the Golconda kingdom gained an important position after that of the Mughal Empire in the north. The old fortified city of Golconda had proved inadequate as the capital of the kingdom, and so Muḥammad Qulī Quṭb Shah, the fifth of the Quṭb Shahs, built a new city called Hyderabad on the east bank of the Musi River in about 1591, a short distance from the old City. Golconda. The Charminar, a grand Indo-Saracen-style architectural composition with open arches and four minarets, is considered the supreme achievement of the Quṭb Shāhī period. It formed the center around which the city was planned. The Mecca Mosque, which was built later, can accommodate 10,000 people. The mosque was bombed in 2007, killing several Muslims and injuring many others. The incident exacerbated tensions between Muslims and Hindus in the city, which has regularly erupted in violence over the years.
