The All Hyderabad Trade Union Congress is founded in Secunderabad.

The All Hyderabad Trade Union Congress (AHTUC) was a trade union centre in the Hyderabad State. Affiliated to the All India Trade Union Congress, it claimed a membership of around 72,000. The trade union centre, which was aligned with the Communist Party of India, was one of the organisations that took part in the Telangana Rebellion against the Nizam regime.

Secunderabad is a twin city of Hyderabad and one of the six zones of the Greater Hyderabad Municipal Corporation (GHMC) in the Indian state of Telangana. It is the headquarters of the South Central Railway zone. Named after the Mir Akbar Ali Khan Sikander Jah, Asaf Jah III, Nizam of the Asaf Jahi dynasty, Secunderabad was established in 1806 as a British cantonment. Although both the cities are together referred to as the twin cities, Hyderabad and Secunderabad have different histories and cultures, with Secunderabad having developed directly under British rule until 1948, and Hyderabad as the capital of the Nizams' princely state of Hyderabad. Since 1956, the city has housed the Rashtrapati Nilayam, the winter office of the president of India. It is also the headquarters of the 54th Infantry Division of the Indian Army. There are also many residential areas and apartments, particularly in the small neighbourhood of Yapral, with many Indian Armed Forces officials living here.
