The spanish explorer pineda did what in 1519?

In 1519, the Spanish explorer Alonso Álvarez de Pineda is best known for mapping the coastline of the Gulf of Mexico, particularly the area that would later become Texas. He was the first European to document this region, creating one of the earliest maps of the North American coastline. Pineda's expedition aimed to find a passage to the Pacific and establish trade routes, contributing significantly to European knowledge of the area. His maps were crucial for subsequent explorers and settlers in the New World.
