About hyderabad

Hyderabad  is the capital of the Indian state of Telangana  Occupying about 650 square kilometres (250 sq mi) along the banks of the Musi River, Hyderabad City has a population of about 6.9 million and about 9.7 million in Hyderabad Metropolitan Region, making it the fourth most populous city and sixth most populous urban agglomeration in India. At an average altitude of 542 metres (1,778 ft), much of Hyderabad is situated on hilly terrain around artificial lakes, including Hussain Sagar—predating the city's founding—north of the city centre.

Established in 1591 by Muhammad Quli Qutb Shah, Hyderabad remained under the rule of the Qutb Shahi dynasty for nearly a century before the Mughals  captured the region. In 1724, Mughal viceroy Asif Jah I declared his sovereignty and created his own dynasty, known as the Nizams of Hyderabad. The Nizam's dominions became a princely state during the British Raj, and remained so for 150 years, with the city serving as its capital. The city continued as the capital of Hyderabad State after it was brought into the Indian Union in 1948, and became the capital of Andhra Pradesh after the States Reorganisation Act, 1956. In 2014, the newly formed state of Telangana split from Andhra Pradesh 

Relics of Qutb Shahi and Nizam rule remain visible today; the Charminar—commissioned by Muhammad Quli Qutb Shah—has come to symbolise Hyderabad. Golconda fort is another major landmark. The influence of Mughlai culture is also evident in the region's distinctive cuisine, which includes Hyderabadi biryani and Hyderabadi haleem. The Qutb Shahis and Nizams established Hyderabad as a cultural hub, attracting men of letters from different parts of the world. Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire in the mid-19th century, with artists migrating to the city from the rest of the Indian subcontinent. 

Hyderabad was historically known as a pearl and diamond trading centre, and it continues to be known as the "City of Pearls". Many of the city's traditional bazaars remain open, including Laad Bazaar, Begum Bazaar and Sultan Bazaar. Industrialisation throughout the 20th century attracted major Indian research, manufacturing and financial institutions, including Defence Research and Development Organization, Bharat Heavy Electricals Limited, Indian Institute of Chemical Technology, the National Geophysical Research Institute and the Centre for Cellular and Molecular Biology. Special economic zones dedicated to information technologyhave encouraged companies from India and around the world to set up operations in Hyderabad. The emergence of pharmaceuticaland biotechnology industries in the 1990s led to the area's naming as India's
