Historically, a continuous Hispanic presence in the territory of the United States has existed since the 16th century, earlier than any other group after the Amerindians. Spaniards pioneered the present-day United States. The first confirmed European landing on the continent was that of Juan Ponce de León, who landed in 1513 on the 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.
