the Seven Cities of Cíbola
Between 1540 and 1542, Francisco Vázquez de Coronado y Luján, a Spanish conqueror and explorer, led a vast expedition through sections of the southwestern United States from what is now Mexico to modern-day Kansas.
Coronado oversaw a significant Spanish expedition that traveled along Mexico's west part and into what is now the western United States in 1540. Despite not finding any of the rumored wealth, the explorers did find the Canyon and other significant geographical features of the area and engaged in deadly conflict with the native people. Coronado returned to Mexico when the Spanish colonial authorities declared his mission a failure, where he passed away in 1554.
