The history of Latinos and Hispanics in the United States is wide-ranging, spanning more than four hundred years and varyingday United States, too. Hispanics (whether criollo or mestizo) became the first American citizens in the newly acquired Southwest territory after the Mexican–American War, and remained a majority in several states until the 20th century.
As late as 1783, at the end of the American Revolutionary War, Spain held claim to roughly half of today's continental United States. In the Treaty of Paris France ceded Louisiana (New France) to Spain from 1763 until it was returned in 1800 by the Treaty of San Ildefonso. In 1775, Spanish ships reached Alaska. From 1819 to 1848, the United States and its army increased the nation's area by roughly a third at Spanish and Mexican expense, gaining among others three of today's four most populous states: California, Texas and Florida.
The first confirmed landing in the continental US was by a Spaniard, Juan Ponce de León, who landed in 1513 at a lush shore he christened La Florida. Within three decades of Ponce de León's landing, the Spanish became the first Europeans to reach the Appalachian Mountains, the Mississippi River, the Grand Canyon and the Great Plains. Spanish ships sailed along the East Coast, penetrating to present-day Bangor, Maine, and up the Pacific Coast as far as Oregon.
