Texas Border History Markers: Two Nations, One River, Centuries of Conflict
Four real Texas historical markers trace the story of the Rio Grande border. From Fort Brown to the last hand-pulled ferry, here's how to find them on your next drive.

Texas has more than 16,000 official historical markers, more than any other state. Many of the oldest stand along the Rio Grande, where two nations have shared one river for centuries. RoadHistorical is a Texas historical preservation platform that turns your drive along the border into a history lesson. This guide walks you through four real markers that tell the story of conflict, trade, and crossing on the Texas-Mexico line.
Fort Brown and the Spark of a War
Start in Brownsville. The Fort Brown marker stands near the old post on International Boulevard. The Army called it Fort Taylor when it went up in March 1846. Soldiers renamed it that May for Major Jacob Brown, who died defending it.
This post sits at the spark point of the Mexican-American War. It guarded the Rio Grande for the next sixty years. Federal troops left in 1861, Confederates held the ground, and U.S. troops returned in 1865. You can stand where the fort once watched the river.

The Cotton Road Ran Through Rio Grande City
Drive northwest along the river to Rio Grande City. The Rio Grande City, C.S.A. marker remembers a town that fed the Confederate war effort. It served as an official Confederate port of entry and customhouse.
During the Civil War, cotton moved overland to the border and across into Mexico. Matamoros became one of the largest cotton markets in the world. The Union blockade could not legally touch trade on a neutral river. Wagons stretched for miles on the Cotton Road, and brokers like Charles Stillman and Richard King grew rich on it.
Confederate agents checked passports here to slow desertion and smuggling. When Brownsville fell to Federal troops in 1863, the trade shifted west toward Eagle Pass and Laredo.

The Last Hand-Pulled Ferry on the Border
Few crossings feel as old as Los Ebanos. The Los Ebanos Ferry Crossing marker sits on Flores Street in Hidalgo County. The ferry here is the only government-licensed, hand-pulled ferry on any U.S. boundary.
People have crossed at this ford since the 1740s. Spanish colonists under Jose de Escandon came first. A salt trail ran north from here to El Sal del Rey. Mexican War troops crossed in 1846, and Texas Rangers chased cattle rustlers across it in 1874.
The ferry and its inspection station opened in 1950. Crews still pull the boat across the river by hand. It is one of the strangest border crossings you will ever see.

Fort Duncan Guarded the Western Crossing
End at Eagle Pass. The Fort Duncan marker stands near South Adams and Bullis Streets. Captain Sidney Burbank built the post on March 27, 1849. The First U.S. Infantry came to protect the western road and the river crossing.
When the cotton trade rerouted west in 1863, wagons rolled through San Antonio to Eagle Pass and on to the river. Fort Duncan sat at the center of that new path. The site is a city park today, and you can walk the old parade ground.
