Los Adaes: Capital of Spanish Texas, Not Texas

Los Adaes was never the capital of Texas. It was the capital of Spanish Texas (Tejas) from 1721 to 1773—a period of 52 years—when Texas was a frontier province of New Spain, not an independent entity or U.S. state.

Context

• Founded 1721: Presidio Nuestra Señora del Pilar de Los Adaes + Mission San Miguel de Linares de los Adaes, near present-day Robeline, Louisiana (just east of the Texas border).
• Purpose: Check French expansion from Natchitoches (12 mi east); administer East Texas missions.
• Capital moved 1773: After Spain acquired Louisiana from France (1763), the French threat vanished. The capital shifted to San Antonio (San Antonio de Béxar), more central and secure.
• Texas independence: 1836 (Republic of Texas). Statehood: 1845. Capitals since: Washington-on-the-Brazos, Harrisburg, Galveston, Velasco, Columbia, Houston, Austin (1839–present).

Today

Los Adaes State Historic Site (Louisiana) preserves archaeological remains. It's a National Historic Landmark—testament to a colonial capital that governed a Texas that didn't yet exist.
