King Felipe of Spain appears to have helped thaw frosty relations with Mexico by acknowledging abuses carried out by his country during its conquest. But in doing so he has reopened a fierce debate over the colonisation 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 also 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, stating it was a significant gesture of reconciliation regarding the excesses during the Spaniards' arrival. The year 2021 marked the 500th anniversary of the fall of Tenochtitlán, the Aztec capital. King Felipe's statements are being viewed by some as the first time a Spanish monarch has publicly acknowledged abuses from the colonial era, and while they are seen as a step toward dialogue, there are varying opinions on how to interpret the past and its implications for modern identity and relations between Spain and Mexico. Political leaders from the right have pushed back, arguing that reflecting critically on historical actions under modern criteria risks misrepresentation and undermines Spain's historical contributions.
