Ghulam Muhammad Ghouse Khan

Ghouse Khan ruled from 1825 to 1842, with Azim Jah as regent, until Ghouse Khan was formally installed as the Nawab of the Carnatic by Viceroy Lord Elphinstone.

During his reign, until his death in 1855, Ghouse Khan established the Muhammadan Public Library in Madras and a choultry called Langar Khana. The Langar Khana now houses the Muslim Widows Association.

Ghouse Khan died in 1855 at the age of 31. He did not leave behind any male heir. The candidature of Ghouse Khan's uncle Azim Jah, the only possible successor to the throne was passed over and the kingdom was formally annexed by the British East India Company as per the Doctrine of Lapse.
