In the United States, it was the beginning of the end for Native American societies, which would go on to suffer extermination through disease, alcohol addiction, and warfare with the Europeans moving to their continent for the centuries that followed. Their land would be stolen from them and the U.S. government would break treaties made with their leaders. The city symbolically renamed Columbus Day as "Indigenous Peoples' Day" beginning in 1992 to protest the historical conquest of North America by Europeans, and to call attention to the losses suffered by the Native American peoples and their cultures through diseases, warfare, massacres, and forced assimilation.
