Herbert Eugene Bolton’s classic of southwestern history, first published in 1949, delivers the epic account of Francisco Vásquez de Coronado’s sixteenth-century entrada to the North American frontier of the Spanish Empire. Leaving Mexico City in 1540 with some three hundred Spaniards and a large body of Indian allies, Coronado and his men—the first Europeans to explore what are now Arizona and New Mexico—continued on to the buffalo-covered plains of Texas and into Oklahoma and Kansas. With documents in hand, Bolton personally followed the path of the Coronado expedition, providing readers with unsurpassed storytelling and meticulous research.
