San Antonio

Location: San Antonio, TX — Bexar County seat; 2nd largest city in Texas
Anchor Site: The Alamo / River Walk / Mission Trail

The Hook

San Antonio is the oldest major city in Texas, the most visited city in Texas, and the only city in Texas where you can walk from a 300-year-old Spanish mission to a UNESCO World Heritage Site to a world-class river district in under twenty minutes. It has been Spanish, Mexican, Texan, American, and Confederate — and it remembers all of it.

Key Facts

Population: ~1.5 million city proper; ~2.6 million metro (San Antonio–New Braunfels MSA)
Founded May 1, 1718 as Villa de Béxar — the same day Mission San Antonio de Valero (the Alamo) was established
One of the longest continuously inhabited cities in Texas; the site had been a Coahuiltecan and later Apache camping ground for centuries before Spanish settlement
~64% Hispanic/Latino population — the largest Hispanic-majority major city in the US
Five Spanish colonial missions (including the Alamo) designated a UNESCO World Heritage Site in 2015 — the only UNESCO WHS in Texas
Home to Joint Base San Antonio, the largest military installation in the US by population (Fort Sam Houston, Lackland AFB, Randolph AFB combined)
The River Walk (Paseo del Río) draws more visitors annually than the Grand Canyon

Story / History

San Antonio began as a strategic Spanish colonial settlement on May 1, 1718 — the same day Governor Martín de Alarcón formally established both the civilian Villa de Béxar and Mission San Antonio de Valero on opposite banks of the San Antonio River. The date was not coincidental: the Spanish Crown needed a permanent settlement midway between the Rio Grande and the mission fields of East Texas, and the San Antonio River’s spring-fed reliability made this the obvious site.

Four more missions followed within a decade — Concepción, San Juan, San José, and Espada — strung south along the river like beads on a string. Each was a self-contained agricultural and religious community, converting Coahuiltecan and other Indigenous peoples and teaching European farming and craft techniques. The mission system collapsed by the 1790s as epidemic disease devastated the Indigenous population, and the missions were secularized in 1793. The Alamo became a military garrison, eventually occupied by soldiers from both sides of every conflict that followed.

The city passed through Spanish, Mexican, and Texan hands in rapid succession. Under Mexican rule it was a provincial capital; under the Republic of Texas it was a military outpost; under American statehood it was a frontier garrison town. The U.S. Army established Fort Sam Houston in 1876, beginning a military relationship with the city that never ended. Theodore Roosevelt recruited his Rough Riders at the Menger Hotel bar in 1898. Eisenhower trained pilots at Kelly Field during World War I. San Antonio today is more dependent on military payroll than any other major American city.

The River Walk’s existence is a quirk of civic stubbornness. After the catastrophic 1921 flood killed 51 people downtown, city engineers proposed paving over the river bend that curved through downtown to create a drainage channel. A group of citizens — led by architect Robert Hugman — proposed instead to develop it as a pedestrian promenade. They won. Construction began in 1939 as a WPA project. The River Walk opened, was largely ignored for two decades, was rediscovered in time for the 1968 World’s Fair (HemisFair), and has been the city’s economic and cultural spine ever since.

Historic Battles

The Battle of the Alamo (February 23 – March 6, 1836)

The most famous battle in Texas history happened in the middle of what is now downtown San Antonio. On February 23, 1836, General Antonio López de Santa Anna arrived at San Antonio with an army of roughly 1,500–6,000 troops (estimates vary widely) and demanded the surrender of the Texan garrison holding the former mission. The garrison’s commander, William Barret Travis, refused and sent out his famous letter: “I shall never surrender or retreat… Victory or Death.”

The defenders — between 185 and 257 men, depending on the source — held the Alamo for 13 days. They included Jim Bowie (ill with typhoid for most of the siege), Davy Crockett (arrived with a company of Tennessee volunteers), and Travis himself. On March 6, Santa Anna ordered a pre-dawn assault. The walls were breached in under two hours. All male defenders were killed; the women, children, and enslaved people inside were released. Susanna Dickinson, wife of defender Almaron Dickinson, was sent by Santa Anna to carry the news to Sam Houston’s army as a warning.

The warning had the opposite of its intended effect. “Remember the Alamo!” became the rallying cry six weeks later at the Battle of San Jacinto (April 21, 1836), where Houston’s army routed Santa Anna’s forces in 18 minutes and secured Texas independence.

The Council House Fight (March 19, 1840)

The Council House Fight was a catastrophic diplomatic failure that directly triggered the Great Raid of 1840 — which in turn produced the Battle of Plum Creek fought on the future site of Lockhart. Penateka Comanche chiefs arrived at the San Antonio courthouse to negotiate the return of captives. Texas commissioners expected all captives returned; the Comanche brought only one, teenager Matilda Lockhart, who reported others were being held. When Texas officials attempted to detain the chiefs as hostages, fighting broke out inside the building. Thirty-five Comanche leaders were killed, along with several Texans. The massacre of the chiefs under a flag of truce permanently poisoned Comanche-Texan relations and set off the retaliatory raid that would devastate the Texas coast.

Frontier Times

San Antonio was the southwestern anchor of the Texas frontier for over a century. It was the last major city before the route south to Mexico and west into Apache and Comanche territory, which made it simultaneously a staging point for military expeditions, a trade hub, and a target. The Camino Real — the Royal Road connecting Mexico City to the Texas missions — ran through San Antonio, making it the commercial spine of Spanish Texas.

The cattle drives that defined the Central Texas economy before the fence-cutting era converged on San Antonio as a supply point. The city was too urban and too established to be defined by the open-range conflict the way Lockhart or Caldwell County were, but the transition from frontier outpost to modern city happened here on the same timeline: the railroads arrived in 1877, cotton and cattle shipped east by rail instead of overland by trail, and the frontier retreated west toward the Pecos.

Local Legend

The Menger Hotel, built in 1859 directly beside the Alamo, has been claiming its bar is where Teddy Roosevelt recruited the Rough Riders since approximately the day after it happened. The actual recruitment took place across the city over several weeks in the spring of 1898, with Roosevelt conducting interviews at various locations including the hotel. The bar — now called the “Roosevelt Bar” and decorated accordingly — is a faithful reproduction of the bar at the House of Lords Club in London, which Roosevelt allegedly admired. Whether Roosevelt cared about the London club aesthetic while recruiting cowboys and frontiersmen for a cavalry regiment that would charge up a Cuban hill is a question no one at the Menger Hotel is interested in entertaining.
