Which explorer mapped the coast of Texas in 1519 and produced the first records of Texas history?

• A. Alonso Alvarez de Pineda
• B. Francisco Coronado
• C. Rene-Robert Cavalier Sieur de La Salle
• D. Fray Damian Massanet

Answer: (A)

Exploration and mapping of the Gulf Coast in the early 16th century produced the first real geographic and historical records of what would become Texas. Alonso Álvarez de Pineda led the 1519 voyage that surveyed and charted the Texas coastline, creating the first known maps of the region and recording observations about the land and its peoples. Those charts gave future explorers a concrete reference and established the earliest written accounts of Texas’s history.

Francisco Coronado’s expedition occurred later, in the 1540s, and focused on the interior Southwest in search of legendary cities. Rene-Robert Cavalier Sieur de La Salle explored the Mississippi basin and claimed lands for France in the late 17th century, with Texas involvement coming after the coast had already been mapped. Fray Damian Massanet is associated with establishing missions in Texas during the late 1600s, not with coastal mapping.

So the explorer who mapped the Texas coast in 1519 and produced the first records is Alonso Álvarez de Pineda.
