After this defeat the importance of Hyderabad declined and the city fell into partial ruins. As the Moghul empire decayed and began to disintegrate, the viceroy, Asaf Jah I proclaimed himself the Nizam and established independence rule of the Deccan. Hyderabad once again became a major capital city, ruled by successive Nizams of the Asaf Jahi dynasty until the state was merged into Indian Union in 1948.
SECUNDERABAD : In 1798, a subsidiary alliance for military and political cooperation was signed between the Nizam and the British East India company.
There after an area north of what is now the Hussain Sagar was established as a cantonment. The area was named Secunderabad after the then Nizam, Sikander Jah.

Persian was the official language up to 1893 and then Urdu up to 1948. When the British and the French spread their hold over the country, the Nizam soon won their friendship without bequeathing his power. The title "Faithful. Ally of the British Govenment" was bestowed on Nizam VII. The British stationed a Resident at Hyderabad, but the state continued to be ruled by the Nizam. The rule of the seven Nizam's saw the growth of Hyderabad both culturally and economically. Huge reservoirs, like the Nizam Sagar, Tungabadra, Osman Sagar, Himayath Sagar, and others were built. Survey work on Nagarjuna Sagar had also begun during this time. Hyderabad, under the Nizam's, was the largest princely state in India. Area wise it was as big as Engl- and and Scotland put together. The State had its own currency, mint, railways, and postal system. There was no income tax. Soon after India gained independence, Hyderabad State merged with the Union of India. On November 1, 1956 the map of India was redrawn into linguistic states, and Hyderabad became the capital of Andhra Pradesh.
