During the Spanish colonial period in America, the Spanish established several royal roads, which tied far-flung regions with Mexico City. One of these was El Camino Real de Los Tejas, also called the Royal Road, the King’s Highway, the Old San Antonio Road, and the San Antonio-Nacogdoches Road. The ever-changing 1,000-mile trail provided the only primary overland route from Mexico City across the Río Grande to Los Adaes, the first capital of the Texas province in present-day northwestern Louisiana. Other Caminos Reales were also established by the Spanish, including the mission trail up the coast of California and the road from El Paso, Texas, to Santa Fe and Taos, New Mexico, known as the El Camino Real de Tierra Adentro.

Not every route used by the Spanish during their exploration and settlement of New Spain met the designation requirements as a Camino Real. Caminos Reales connected economically important Spanish towns, provinces’ capitals, and mines with charters conferring royal privileges.

Following established Indian trails and trade routes, it was first blazed by several Spanish expeditions in the late 17th Century to connect a series of Spanish missions and posts. It was also developed to confront and counter French and English intrusion into the northeastern frontier of the Spanish borderlands. Settlements that formed along the road were among the state’s earliest cities and communities.

The blazing of the trail was the result of three expeditions. In 1690 Alonso De León led his fourth expedition into Texas to establish the short-lived San Francisco de Los Tejas Mission in present-day Houston County. The following year, Domingo Terán de Los Ríos, the first provincial governor of Texas, crossed the Rio Grande taking additional missionaries to the East Texas missions. Following much of the same course traveled by De León, Terán diverted his path to send a party to Matagorda Bay to meet supply ships. In 1693 Gregorio de Salinas Varona proceeded directly from the Rio Grande to the East Texas missions, further defining the course as a direct route.

Though sometimes thought of as a single road, it is more accurate to describe the El Camino Real de Los Tejas as a network of trails with different routes used at different times. Numerous feeders branched off the main course. Other segments didn’t appear until much later, with the trails coming together at San Antonio and Nacogdoches, the only two population centers in those early days. The trail also varied due to flooding and Indian threats.

The route between the Rio Grande and San Antonio gradually shifted southeastward over time due to the Apache and Comanche tribes’ threats. In the beginning, it was almost exclusively utilized by Spaniards moving northeastward, serving as a lifeline for the missions, as a trade route, and as a cattle trail. However, by the 1820s, numerous Anglo immigrants began to utilize the trail from Nacogdoches to new settlements further west. Moses Austin traversed the trail en route to San Antonio to request an empresario grant from the Spanish government in 1820. Many Anglo-American colonists entered Texas at Gaines Ferry on the Sabine River, arriving at Nacogdoches and the interior of Texas. Parts of these roads were not only used for travel; they also formed some of the earliest political boundaries, such as separating land grants and becoming county lines.

The El Camino Real de Los Tejas provided access to armies on the move, including Spanish, French, Mexican, Republic of Texas, and American, and helped determine the southern and western boundaries of the United States and Mexico. Thousands of American immigrants to Texas arrived via a section of the Camino Real known as the San Antonio Road. Their presence and activities led to the revolt against Mexico, Texas’ independence, and eventual statehood.

Constituting the only primary overland route from the Río Grande to the Red River Valley for more than 150 years, the trail served as a conduit for exploration, trade, migration, settlement, and agent of change. Connecting cultural and linguistic groups, the pathway fostered a mix of Spanish and Mexican traditions, laws, and cultures with those of Anglo-Americans, resulting in a rich legacy reflected in the people, places, music, and arts of Texas and Louisiana today.

After Texas independence, the road fell into disuse as the greater emphasis was on north-south routes. Courses shifted to accommodate new settlements and markets and provide coastal trade access. Shortly after the Mexican-American War, the Old San Antonio Road regained some of its former importance as potential prospectors flocked westward during the California Gold Rush.

Later, during the Civil War, the road served as a significant route for troops and supplies transportation. After the war, large segments of the route were abandoned in favor of newer, shorter roads that linked Texas’ growing cities. In the latter part of the 19th century, when the railroads barreled through Texas, almost all roads were abandoned except for local transportation. However, later highways would follow similar paths, including I-20,  U.S. Highway 59, and Texas Highway 21.

In 1915, the Texas Legislature appropriated $5,000 so that a survey could be made of the Old San Antonio Road through Texas, and the Daughters of the American Revolution soon erected pink granite markers along the old trail. On the 300th anniversary of the old road, in 1991, the Old San Antonio Road Preservation Commission was formed to study the historical and archeological evidence along the old route.

In 2004, Texas Senator Kay Bailey Hutchison persuaded Congress to designate El Camino Real de Los Tejas in Texas and Louisiana as a national historic corridor. The path makes its way from Mission San Juan Bautista Guerrero, Coahuila, Mexico, to Fort St. Jean Baptiste Natchitoches Parish in Natchitoches, Louisiana. Today, the National Park Service administers El Camino Real de Los Tejas in partnership with other federal, state, and local agencies, non-profit organizations, and private landowners.
