David E. Stannard argued in his best-known book that this system, utilized by an “optimizing imperialist,” contributed to a “magnification of the firestorm of human devastation.” This system evolved from a medieval system that granted nobles a title translated as “advanced” (-5[1])for being “one who goes before.” People under this system were often forced into settlements (-5[1])known as reductions. (10[2]-5[4])This (10[1])system (10[1]-5[1])was gradually (10[1])phased (10[1])out after the passage of the New Laws under (10[1])Charles (10[2]-5[1])I, (10[1])which replaced (10[1])this system with the repartimiento (10[1]-5[2])system. (10[4]-5[2])In the (10[1])Valladolid (10[1]-5[1])debate, (10[2])Juan (10[3])Ginés (10[1])de (10[1])Sepúlveda (10[3]-5[1])defended this system (10[1])against (10[1])Bartolomé (10[4])de las Casas. (10[4])For 10 points, name this (-5[1])colonial system where Spanish conquistadores (10[3])extracted tribute and labor from indigenous subjects (10[1])on their land. (10[1])■END■ (10[4]0[7])
