The word pre-Columbian refers to the era before Christopher Columbus, but sometimes it can include the history of American indigenous cultures as they continued to develop after the Christopher Columbus' first landing in 1492, until they were conquered or influenced by Europeans, even if this happened decades or even centuries after the arrival of Columbus.
