The Narváez expedition was a Spanish journey of exploration and colonization started in 1527 that intended to establish colonial settlements and garrisons in Florida. The expedition was initially led by Pánfilo de Narváez, who died in 1528. Many more people died as the expedition traveled west along the explored Gulf Coast of the present-day United States and into the American Southwest. Only four of the expedition’s original members survived, reaching Mexico City in 1536. These survivors were the first known non-Native Americans to see the Mississippi River, and to cross the Gulf of Mexico and Texas.
