The Las Casas Revolt – Prelude to Revolution in Early Texas

The Casas Revolt was the first significant armed challenge to Spanish royal authority in Texas during the Mexican War of Independence. It occurred in San Antonio de Béxar between January 22 and March 2, 1811 (lasting only 39 days) and was directly inspired by Father Miguel Hidalgo y Costilla's Grito de Dolores and the early successes of the Hidalgo insurgency in central Mexico.^[a]

The revolt aimed to remove European-born (gachupín) officials from power and place local or American-born leadership in control, aligning Texas politically with the broader Mexican independence movement.^[a]

The Coup – January 22, 1811

Background & Trigger

By late 1810, news of Hidalgo’s uprising had reached Texas. Governor Manuel María de Salcedo (Spanish Royalist governor) responded by imprisoning suspected sympathizers, including revolutionary agents Antonio Saenz and Francisco Ignacio Escamilla, both sent from Nuevo Santander.^[b]

Local discontent — especially resentment toward peninsular officials, economic restrictions, and high-handed governance — created fertile ground for revolt.^[a]

The Night of the Coup

On the night of January 21–22, 1811, Juan Bautista de las Casas (Mexican revolutionary / insurgent leader), a retired militia captain originally from Nuevo Santander living in San Antonio, led a group of disgruntled local militia and sympathetic residents in a virtually bloodless coup.^[c]

Key actions during the night:

• Arrested Governor Manuel María de Salcedo and virtually the entire military and civil staff
• Also arrested Simón de Herrera (Spanish Royalist), interim governor of Nuevo León who was temporarily in San Antonio
• Seized the presidio, armory, and royal treasury
• Released political prisoners including Antonio Saenz and Francisco Ignacio Escamilla

The coup was accomplished without a single shot being fired.^[a]

Casas’s Brief Rule (January 22 – March 2, 1811)

Measures Taken by Casas

Juan Bautista de las Casas proclaimed himself head of a provisional revolutionary government and took the following steps:

• Declared allegiance to the Hidalgo revolution
• Confiscated property belonging to peninsular (European-born) Spaniards
• Opened Texas to free trade with the United States (a very popular measure)
• Appointed local supporters to key positions
• Attempted to govern as interim governor of Texas (with some recognition from Coahuila revolutionaries)

^[d]

Reasons for Rapid Decline

Casas’s government quickly lost support for several critical reasons:

• His increasingly dictatorial and arbitrary style alienated the local elite (cabildo) and many moderate Tejanos
• He showed clear favoritism toward relatives and close allies (nepotism)
• He failed to build a broad coalition or show diplomatic restraint
• Most damaging — news arrived that Father Miguel Hidalgo had been captured and defeated in Coahuila (March 1811)

These developments convinced many residents that the revolutionary cause was failing and that supporting Casas had become politically dangerous.^[a]

The Counter-Coup – March 2, 1811

Organization of the Counter-Revolution

A coalition of local notables, moderate Tejanos, and royalist sympathizers quickly organized under Juan Manuel Zambrano (counter-revolutionary / royalist leader), a Bexar native, former lieutenant colonel, and controversial churchman.^[e]

Juan Manuel Zambrano was elected president of a governing junta that included many prominent local figures.^[a]

Key Participants in the Counter-Revolution

• Juan Manuel Zambrano – leader of the junta
• Ignacio Pérez – captain and military figure
• Erasmo Seguín – prominent Tejano landowner
• Juan Veramendi – local leader
• Francisco Ruiz – early conspirator
• Miguel Eca y Múzquiz, José Antonio de la Garza, Fernando Veramendi – other junta members

The Arrest & Restoration

In the early morning hours of March 2, 1811, the junta’s forces arrested Juan Bautista de las Casas and his main ally Ignacio Aldama without serious resistance.^[a]

Governor Manuel María de Salcedo was immediately restored to power and royalist control was reestablished.^[a]

Aftermath & Execution of Casas

Juan Bautista de las Casas was sent to Monclova, Coahuila for trial.

He was found guilty of treason, sentenced to death, and executed by firing squad on August 3, 1811.

Following Spanish custom for traitors, he was shot in the back and then beheaded.

His severed head was returned to San Antonio and publicly displayed on a pole in Military Plaza as a stark warning to potential rebels.^[g]

Historical Significance

Although brief and ultimately unsuccessful, the Casas Revolt had several important long-term consequences:

• It demonstrated that Spanish control of Texas was fragile and could be challenged from within
• It proved that San Antonio de Béxar could be taken with relatively little bloodshed
• It created important precedent and psychological impact for the much larger Gutiérrez-Magee Expedition the following year (1812–1813)
• It showed significant participation by local Tejanos in the independence struggle
• It dramatically increased American awareness of — and commercial interest in — Texas
• It contributed to the growing sense of political volatility along the northeastern frontier of New Spain

The Casas Revolt was the first in a chain of revolutionary episodes in Texas between 1811 and 1821 that ultimately weakened Spanish authority and prepared the way for both Mexican independence and the later Anglo colonization of Texas.^[a]
