Castro, Américo (ämāˈrēkō käsˈtrō) [key], 1885–1972, Spanish philologist and literary critic, b. Brazil. After the Spanish Civil War, Castro's studies focused on how modern Spanish history was adversely affected by the shift of Spain's military and political power from Muslim to Christian forces (11th–15th cent.) and by the expulsion of the Jews in 1492.
