Governor Marquis de San Miguel de Aguayo
Nacogdoches, Nacogdoches County, Texas
Marker Inscription
In 1719, Jose de Azlor y Virto de Vera, the Marquis de San Miguel de Aguayo (d. 1734), replaced Martin de Alarcon as Governor of Texas. His appointment coincided with war between Spain and France which prompted Aguayo to send an expedition to East Texas to secure its border with Louisiana. He renamed the province Nuevas Filipinas (New Philippines) to emphasize Spanish jurisdiction over the territory. He requested Father Felix Isidro Espinosa and Father Antonio Margil de Jesus to join the expedition in order to reestablish the six previously abandoned Tejas missions. Then in 1721, Aguayo marched from his headquarters in Monclova with 584 soldiers, missionaries and caretakers to East Texas. The entrada was the largest ever to occur in Spanish Texas. During the expedition, Aguayo allied with native groups, including the Rancheria Grande and Caddo. On July 25, 1721, Aguayo met with the leader of the Hainai and his interpreter Angelina, who pledged loyalty to him and Spain. When Aguayo neared the missionary fields at the Neches River, Louis Juchereau de St. Denis, new commandant of the French fort Saint Jean Baptiste, requested a meeting with Aguayo. St. Denis informed the governor that war between the two nations had ceased. With this new development, Aguayo pressed St. Denis to abandon his invasion of Texas. St. Denis withdrew and Aguayo began to reestablish the missions. In addition to Presidio Dolores, he added Presidio Nuestra Senora del Pilar de los Adaes, a fortification only fourteen miles from the French outpost of Natchitoches. Aguayo's performance as governor reaffirmed Spanish supremacy in Tejas, and prevented any further French claims to the region. (2015)

The Story
In 1719, as Spain and France clashed over their overlapping colonial claims, the Marquis de San Miguel de Aguayo took over as governor of Spanish Texas and set out to secure its eastern frontier. In 1721 he led the largest entrada ever mounted in Spanish Texas—nearly 600 soldiers, missionaries, and caretakers—reestablishing six abandoned missions and building presidios that anchored Spanish authority against the nearby French. Along the way he forged alliances with Caddo and Hainai leaders, and negotiated a French withdrawal after learning the two crowns were no longer at war.
Why it matters
Aguayo's expedition cemented Spain's hold on East Texas and drew the enduring boundary between Spanish and French North America, shaping the region long before it became part of the United States.
The story behind this marker
AI contextThe era
By 1719, the quiet contest between Spain and France for the East Texas frontier had turned into open trouble. The two crowns were at war in Europe, and that conflict rippled all the way to the piney woods, where Spanish missions sat uncomfortably close to French Louisiana. When settlers abandoned the East Texas missions that year under French pressure, Spain faced a hard question: would it hold this borderland, or let it slip away?
Into that moment stepped a new governor of Texas, José de Azlor y Virto de Vera, the Marqués de San Miguel de Aguayo. His appointment coincided with the war, and he understood immediately that securing the border with Louisiana was now the central task of his office. To underline Spain's claim, he even gave the province a grand new name, Nuevas Filipinas — New Philippines — a flourish meant to leave no doubt about whose jurisdiction this was.
This was the frontier at its most fluid: a place where a single expedition, well led, could redraw the boundary between two empires and decide the fate of a whole region for generations.
People & events
Aguayo did not intend to hold Texas with words alone. He asked two experienced friars, Father Félix Isidro Espinosa and Father Antonio Margil de Jesús, to join him and reestablish the six previously abandoned missions of the Tejas. Then, in 1721, he marched from his headquarters at Monclova with 584 soldiers, missionaries, and caretakers — the largest entrada ever mounted in Spanish Texas.
As he advanced, he built alliances rather than simply imposing force, reaching agreements with Native groups including the Ranchería Grande and the Caddo. On July 25, 1721, he met with the leader of the Hainai and that leader's interpreter, Angelina, who pledged loyalty to Aguayo and to Spain — a moment of diplomacy that mattered as much as any show of arms.
The expedition's turning point came near the mission fields by the Neches River. There, Louis Juchereau de St. Denis, the new commandant of the French fort, requested a meeting and informed Aguayo that the war between their nations had ended. Aguayo seized the opening, pressing St. Denis to abandon any incursion into Texas. St. Denis withdrew. With the French pulled back, Aguayo set about reestablishing the missions and added two presidios — including one just fourteen miles from a French outpost, a deliberate marker of Spanish resolve planted almost on France's doorstep.
Its place in the American story
Aguayo's expedition is one of those quiet hinge points that shaped the map of North America long before the United States existed. By reoccupying the missions, building presidios, and facing down the French, he reaffirmed Spanish supremacy in Tejas and effectively closed the door on further French claims to the region. The boundary between Spanish and French North America hardened here, in the East Texas woods.
What makes the story especially telling is how Aguayo secured that boundary. His was the largest entrada in Spanish Texas history, yet its decisive moments were diplomatic — an alliance sealed through an interpreter's pledge, a rival commander persuaded to withdraw once news of peace arrived. Empire on this frontier advanced as much through negotiation and presence as through battle.
That enduring line between Spanish and French spheres would echo for generations, shaping the cultures, land claims, and identities of the region long after both empires faded. When this country eventually became part of the United States, it carried that colonial inheritance with it. Aguayo's march is a reminder that the American story has deep Spanish roots reaching back well before the nation's founding.
If you visit
At this marker in Nacogdoches, you are standing in the country that Aguayo crossed with nearly six hundred people at his back — the largest such expedition Spanish Texas ever saw. It takes a moment of imagination to populate the quiet modern landscape with that long column of soldiers, friars, and caretakers, but the marker gives you everything you need to try.
As you read, trace the drama in your mind: the march from distant Monclova, the alliances struck along the way, the meeting near the Neches River where a French commander agreed to withdraw, and the presidio planted boldly close to the French frontier. This was high-stakes frontier diplomacy, and it played out across the very ground of East Texas.
For road-trippers, this is an ideal stop for anyone interested in how the borders of early America were actually drawn. Nacogdoches is rich in Spanish colonial history, and this marker helps you read the region as a former imperial frontier — a place where an expedition, rather than a war, settled the question of who would claim the land.

Governor Martin de Alarcon in East Texas
Nacogdoches, TX
Martin de Alarcon became governor of Spanish Texas in 1716 with a mandate to plant a secure presidio along the San Antonio River to supply the frontier missions. In 1718 his expedition founded the villa of San Fernando de Bexar—today's San Antonio—along with the mission San Antonio de Valero, later famous as the Alamo. Though missionaries resented his crackdown on French trade, his settlement and the turmoil that followed a 1719 French raid laid the foundations for one of Texas's great cities.
On This Site Stood for a Century an Old Stone House
Nacogdoches, TX
For roughly a century a stone house stood on this Nacogdoches site, thought to have been built about 1779 by town founder Antonio Gil Ybarbo and sold by him in 1805. It later served as headquarters for Indian traders William Barr and Samuel Davenport and, over its long life, did duty as trading post, warehouse, town hall, fort, barracks, church, tavern, and saloon before being demolished in 1902. A reconstruction rose in 1936 on the college campus.
Site of "Old Soledad"
Nacogdoches, TX
Before 1800, this spot was known across East Texas as "Old Soledad," the headquarters of William Barr and Samuel Davenport, licensed traders who did business with the region's Native nations. In the Spanish borderlands, such traders were the crucial go-betweens, exchanging manufactured goods for hides and deerskins and knitting frontier economies together. A 1936 state marker fixes the site's place in that vanished world.
Site of the Home of James Dill
Nacogdoches, TX
James Dill came from Pennsylvania to the Texas-Louisiana borderlands as a frontier Indian trader in the era when this country was still ruled from Mexico City. Trusted by Spanish authorities, he became the first alcalde — roughly a mayor and magistrate — of Nacogdoches under the new Mexican government in 1821. The State of Texas marked his home site during the 1936 Centennial.
