The All-India Yadav Mahasabha is a caste association established in 1924 for serving a broad body of Indian social groups mainly composed of Nandvanshi, Gwalvanshi and Yaduvanshi castes collectively known as the Yadav caste.
The emergence of an English-educated elite among the Yadavs led to the formation of the All-India Yadav Mahasabha in 1924 in Allahabad. The AIYM immediately engaged itself in two issues. It appealed to its castemen in all regions to add "Yadav" to their names and at the same time launched on a major programme of social reform. The regional organisation of the Gollas of Hyderabad, the Hyderabad Rashtra Yadav Mahajana Samajam, for example, appealed to the Census Commission that their caste names of Golla, Gowli, Gollawar and Ahir be changed to Yadava.
In the mid-20th century the Mahasabha pressed Indian government for the formation of Yadav regiment in Indian Army after they showed their performance in the 1962 Indo-China war.
