Kamma is a Hindu caste from South India. The community of Kammas is believed to have originated from agriculturists of the Kammanadu region of the Guntur and Prakasam districts in Andhra Pradesh. Propelled by their military activity in the Vijayanagara Empire, Kammas are believed to have spread out from the region during the Vijayanagara period, followed by some in-migration during the British period and out-migration again during the twentieth century.Today they are regarded as the richest group in Andhra Pradesh and are a dominant caste from Coastal Andhra with socio-economic and political prominence throughout the Telugu-speaking regions of India (the states of Andhra Pradesh and Telangana).
