Francisco Vasquez de Coronado, famous for leading an expedition through Arizona in 1540, was sponsored primarily by his wife and Viceroy Mendoza. Other people invested in Coronado's journey in the hopes of becoming wealthy when he found precious metals and jewels.
Coronado set out from Mexico to explore parts of the "Seven Golden Cities" when he heard rumors that there was treasure to be found in the southwestern United States. He led an expedition that began in 1540, and led to him being disgraced when no riches were ever found. Although he and his party of explorers discovered things like the Grand Canyon, his mission was considered a failure and he died in his home country of Mexico in 1554 without ever leading another expedition.
