There are numerous studies that, from different perspectives, have dealt with the debate held in the Spanish Empire during the 16th century on the slavery of the American Indians, starring –among others– by Francisco de Vitoria and his disciples from the School of Salamanca, and also –outside the academic sphere– by Fray Bartolomé de las Casas and Juan Ginés de Sepúlveda. The purpose of this work is to study whether this debate made its mark in Spanish society. For this, it (...) is analyzed three theatrical pieces from the Golden Age signed by playwrights of the stature of Tirso de Molina, Lope de Vega and Pedro Calderón de Barca, who –given their enormous popularity– had the capacity to reach the wide audience that congregated in the corrals of comedies. Were these three writers influenced by the controversy over the Indians carried out, among other authors, by Vitoria, Las Casas and Sepúlveda? Did they fully grasp in their works the subtle debate that Vitoria, Las Casas and Sepúlveda maintained when they interpreted Aristotelian arguments on slavery and the consequences that derived from them in terms of the possibility of enslaving or not the Indians?
