Samba de Roda is the precursor of Samba originating in the Recôncavo region of Bahia, Brazil, during the 17th century. It’s a cultural tradition combining music, dance, and poetry, with roots in the dances and traditions of African slaves in the area according to UNESCO. The term "Recôncavo" refers to the coastal area surrounding the Bay of Todos os Santos.
