The mythical city of Cíbola and the search for a new El Dorado led Francisco Vázquez de Coronado to the south of what is now the United States. For the first time, European eyes saw those lands: immense deserts, red canyons, great plains full of bison, dangerous indigenous tribes, among them the Apaches... These were years of conquest and evangelization of a still unknown part of the New World, years plagued by confrontations and illnesses, but also by glories and ambitions achieved. Times that saw massacres on both sides, suffered and committed, and events as fundamental in history as the fall of the Mexican civilization. Yet at the same time, they were, like all times, times of human beings who lived, suffered, loved and died; men and women (the latter with a forgotten role), who made up a world that dazzles us even today.
