A mythical gold-rich land sought by the Spanish conquistadors in the 16th century, legendary cities of splendor and riches. The fabulous cities were first reported by Alvar Núñez Cabeza de Vaca who, after being shipwrecked off Florida in 1528, had wandered through what later became Texas and northern Mexico before his rescue in 1536. In 1540, Francisco Vázquez de Coronado was sent to search for the cities; he found only a group of Zuni pueblos, though he had explored as far north as modern Kansas.
