Andhra Mahasabha (Telugu: ఆంధ్ర మహాసభ, IAST: Āndhra mahāsabha) was a people's organisation in the erstwhile Hyderabad state of India.
In the late 1920s, under the leadership of Madapati Hanumantha Rao, the Telugu people united and formed a union and organized 13 Andhra Mahasabhas from 1930 to 1945.
The territory of the state included present-day Telangana, Marathwada (Maharashtra) and parts of Karnataka.
Due to the royal devotion of the British government of the Nawab, special attention was paid to the Christians.
It started with a mere 12 members after a failed attempt to pass a resolution in Telugu at Nizam's Social Reforms Conference in Hyderabad.
Membership quickly increased to about a hundred and its first conference was held in February 1922 under the chairmanship of Konda Venkata Ranga Reddy with Madapati Hanumantha Rao as its secretary.
Some young people who noticed the insult done to the Telugu language and the Telugu speaker in that assembly, came together and founded the "Andhrajana Sangam" (Association of Andhra People) with the ambition to give a proper place to the Andhra language and culture in the city.
Two years later, the Nizam formed an Andhrajana Kendra Sangham (Central Association of Andhra People) to unite all the Telugu organizations in the state.
Any Telugu organization in the Nizam's state could send its representative to this central association.
The sporadic movements for the revival of Telugu language and culture under the leadership of the Andhrajana Kendra Sangam and against the feudal oppressions reached the Revolution in the higher level like a great river joining all the streams.
