what is the difference between kamma and kapu
Kapu (caste) Kāpu literally means cultivator or agriculturist in Telugu.[2] Various subgroups of kapus branched off into separate communities in the post-Kakatiya period (Velamas, Panta Kapus and Pakanati Kapus—both of whom got labelled Reddys, and Kapus of Kammanadu—eventually labelled Kammas).[3] The remaining kapus continue to use the original label. All the cultivator caste clusters have a common ancestry in the legends.[4] According to Cynthia Talbot, the transformation of occupational identities as caste labels occurred in the late Vijayanagara period (17th century) or later.[5]
