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 stated that there had been a lot of abuse during the conquest of the territory that would become Mexico. He noted, There are things that, when we study them, with our present-day criteria, our values, obviously cannot make us feel proud.

These comments have sparked mixed reactions. Mexican President Claudia Sheinbaum welcomed the king's remarks as a positive step towards reconciliation, acknowledging that it is a gesture of recognition of past excesses and exterminations.

The year 2021 marked the 500th anniversary of the fall of Tenochtitlán, the capital of the Aztec empire. King Felipe's acknowledgment of historical wrongs represents unprecedented public recognition by a Spanish monarch regarding the abuses of the colonial era.

However, the response within Spain has been polarized. While many in the socialist government endorsed the king's words, leaders from the conservative People's Party and the far-right Vox party criticized them, arguing that they distort historical context and legitimacy.

King Felipe's remarks, shared in a video on social media, have rekindled the conversation about colonial legacies and the responsibility of nations to address their historical actions, highlighting significant diplomatic tensions that continue to influence Spain-Mexico relations.
