 Many "conversos", now freed from the anti-Semitic restrictions imposed on Jewish employment, attained important positions in fifteenth-century Spain, including positions in the government and in the Church.Among many others, physicians Andrés Laguna and Francisco Lopez Villalobos (Ferdinand's court physician), writers Juan del Enzina, Juan de Mena, Diego de Valera and Alonso de Palencia, and bankers Luis de Santángel and Gabriel Sánchez (who financed the voyage of Christopher Columbus) were all "conversos".
