Until the 19th century, Hyderabad was known for the pearl industry and was nicknamed the "City of Pearls", and was the only trading centre for Golconda diamonds in the world. Many of the city's historical and traditional bazaars remain open. Hyderabad's central location between the Deccan Plateau and the Western Ghats, and industrialisation throughout the 20th century attracted major Indian research, manufacturing, educational and financial institutions. Since the 1990s, the city has emerged as an Indian hub of pharmaceuticals and biotechnology and information technology. The formation of the special economic zones of Hardware Park and HITEC City, dedicated to information technology, has encouraged leading multinationals to set up operations in Hyderabad.

The Hyderabad State Forces were the armed forces of the princely state of Hyderabad. People from both India and abroad were recruited into the Forces. Among these groups were Arab nationals like Chaush and African nationals like Siddis who now stay in Barkas and A. C. Guards areas of Hyderabad respectively. The Hyderabad cavalry was chiefly composed of Muslim castes such as Mughals, Pathans, Syeds, Sheikhs and Balochs. They were principally recruited from the Deccan, but Delhi, Lucknow, Shahjahanpur, Sindh and Balochistan also supplied recruits to bolster ranks. These non-indigenous soldiers were known as the "Rohollas". The Hindus made a very small portion of the cavalry. The Nizam of Hyderabad also had about 1200 Sikh guards. Other battalions within the army were referred to with the suffix "-walas". Some troops were also supplied by the Europeans for the security of the Nizam. (Full article...)
