Historical events are always complex, and the context of the time and its cultural values must be taken into account in order to understand them from today's perspective. Even so, there are values and contexts that have no justification today and, therefore, are a stain on the countries that were the protagonists of events that today may seem reprehensible to us. No one can now accept, for example, slavery or the Inquisition. The same happens with the colonising processes of the 19th century, which in part continue to affect some continents, especially Africa, and, of course, with the "conquest" or colonisation of America by the Spanish Empire – and others. These in large part meant the extinction and deculturation of the original populations, either by systematic and violent persecution, or the diseases they brought, which killed millions of people.
