At the conclusion of the debates, the judges argued amongst themselves and then scattered without any definite decision. For several years the
Council of the Indies pressed the participants to issue an opinion. Apparently, most of the judges wrote their own statements, but these have never been recovered, with the exception of one by the Doctor Anaya, who approved of the conquests in order to spread Christianity and stop certain Indigenous activities viewed as sinful, but added the caveat that the conquests must be undertaken "for the good of the Indians and not for gold." The
junta never issued a collective decision. In the end, while both parties declared that they had won the debate, neither received the outcome they desired.
Las Casas did not see the end to Spanish wars of conquest in the New World, and Sepúlveda did not see the
New Laws' restrictions on the power of the
encomienda system overturned. The debate cemented Las Casas's position as the lead defender of the Indigenous peoples in the Spanish Empire, Sepúlveda's arguments contributed to the policy of "war by fire and blood" that the
Third Mexican Provincial Council implemented in 1585 during the
Chichimeca War. According to
Lewis Hanke, while Sepúlveda became the hero of the
conquistadors, his success was short-lived, and his works were never published in
Spain again during his lifetime. Las Casas's ideas had a more lasting impact on the decisions of the king,
Philip II, as well as on history and
human rights. Las Casas's criticism of the encomienda system contributed to its replacement with
reducciones. His testimonies on the peaceful nature of the
Indigenous peoples of the Americas also encouraged nonviolent policies concerning the religious conversions of the Indigenous peoples in
New Spain and
Peru. It also helped convince more
missionaries to come to the Americas to study the indigenous people, such as
Bernardino de Sahagún, who learned the native languages to discover more about their cultures and civilizations. Ultimately, however, the impact of Las Casas's doctrine was also limited. In 1550, the king had ordered that the conquest should cease, because the Valladolid debate was to decide whether the war was just or not. But the government's orders were hardly respected: conquistadors such as
Pedro de Valdivia went on to wage war in
Chile during the first half of the 1550s. Expanding Spanish territory in the New World was allowed again in May 1556, and a decade later, Spain began its conquest of the
Philippines. Las Casas's ethical arguments offer a reflection on the question of
jurisdiction, asking whether law can be applied internationally, especially in so-called 'rogue states'. The debate also holds a place in contemporary
just war theory, as scholars aim to expand within
war studies. ==Reflection in art==
