King Felipe of Spain appears to have helped thaw frosty relations with Mexico by acknowledging abuses carried out by his country during its conquest. In doing so he has reopened a fierce debate over the colonization of the New World.

The arrival of Spaniards in America from the late 15th Century spread Christianity and the Spanish language across the continent while causing the death of many thousands of indigenous people through military action and disease.

During a visit to an exhibition dedicated to indigenous women in Mexico at Madrid's National Archaeological Museum, King Felipe said there had been a lot of abuse during the conquest of the territory that would become Mexico. There are things that, when we study them with our present-day criteria, our values, obviously cannot make us feel proud, he added.

Mexican President Claudia Sheinbaum welcomed the comments as a major step forward on an issue that has caused diplomatic friction between the two countries in recent years. One could say that it is not everything we would have wanted but it is a gesture of reconciliation by the king in terms of what we were talking about: an acknowledgment of excesses, exterminations that happened during the Spaniards' arrival, she remarked.

The year 2021 marked the 500th anniversary of the fall of Tenochtitlán, the site of modern-day Mexico City and the capital of the Aztec empire, at the hands of Hernán Cortés and his small army. King Felipe's words mark the first time that a Spanish monarch has publicly acknowledged abuses during the country's colonial era. They were included in a video posted on social media by the Royal Household.

However, the political right, which has historically rejected calls for a reassessment of Spain's colonial past, was less enthusiastic with the king's comments. Alberto Núñez Feijóo, leader of the conservative People's Party, cautioned against looking at historical events out of context and emphasized his pride in Spain's legacy in the New World.

The comments are expected to lead to further dialogue on the historical narrative and its implications for contemporary Spain-Mexico relations.
