The history of the Madanu surname is deeply intertwined with the history of the Thogata Veera Kshatriya community in South India. According to community lore, their mythological origin traces to Pushpandajudu, who was born from a lotus after an incident with Amruta Kalasham water. This mythological narrative suggests a deep historical root in South India, particularly in the Rayalaseema region.
Archaeological and historical evidence points to a well-established presence in the region by the pre-colonial period, with the community primarily engaged in weaving and textile production. The surname likely evolved with the formalization of family identities during this period, though exact documentation is limited.
