That seam was drawn in 1846. When the United States and Mexico went to war over the border, General Zachary Taylor — later a U.S. president — built a fort on the north bank of the Rio Grande, and the war's first major battle was fought a few miles away at Palo Alto on May 8, 1846, followed the next day by Resaca de la Palma. The fort took the name Fort Brown, for Major Jacob Brown, who fell in its defense. Today the Palo Alto Battlefield is a National Historical Park — the only national park unit devoted to that war — preserving the ground where the conflict began.
In the decades that followed, Brownsville settled into its real character: a border city that lived by the river. Cotton and cattle moved through during the Civil War and after; the deepwater Port of Brownsville and the international bridges made it a gateway for trade between Texas and Tamaulipas. Spanish, Mexican, and Anglo traditions blended into a single Rio Grande Valley culture — the food, the music, the language all crossing the bridge daily. By the twentieth century Brownsville was the largest city in the valley and, sitting at the very bottom of Texas, the southernmost city on the U.S. mainland.
Why People Visit Brownsville
Visitors come to Brownsville for a mix found nowhere else: battlefield and border history, world-class birding among the resacas and palms, and a living binational culture of music, food, and festival. The Gulf beaches are a short drive, Matamoros a few blocks across the river, and the Charro Days fiesta turns late winter into a two-nation celebration. Equal parts Texas heritage and Rio Grande Valley warmth, Brownsville rewards anyone drawn to the place where the river meets the Gulf.
