John the Conqueror

John the Conqueror, also known as High John de Conqueror, John, Jack, and many other folk variants, is a folk hero from African-American folklore. He is associated with the roots of Ipomoea purga, the John the Conqueror root or John the Conqueroo, to which magical powers are ascribed in African-American folklore, especially among the Hoodoo tradition of folk magic. Muddy Waters mentions him as Johnny Cocheroo in the songs "Mannish Boy" and "I'm Your Hoochie Coochie Man". In "Mannish Boy", the line is "I think I'll go down/To old Kansas too/I'm gonna bring back my second cousin/That little Johnny Conqueroo". This line is borrowed from the Bo Diddley song "I'm a Man", to which "Mannish Boy" is an answer song. In "I'm Your Hoochie Coochie Man", it is called "John De Conquer Blue".
