Don Martin De Leon
Port Lavaca, Calhoun County, Texas
Marker Inscription
After independence from Spain, Mexico utilized the Empresario System to settle the province of Texas with loyal citizens. Seeing his opportunity, Don Martin de Leon applied on April 8, 1824, to the provincial delegation of San Fernando de Bexar for an Empresario Grant. Just five days later, he received his grant which, of all Texas Empresarios, was second only to Stephen F. Austin’s in terms of success and helped carve the central Texas gulf coast out of the wilderness. Don Martin de Leon was born in Cruillas, Nuevo Santander (modern-day Tamaulipas), Nueva Espana. Around 1790, he joined the military and reached the rank of captain. In 1795, he married Dona Patricia de la Garza. Between 1798 and 1801, the family moved to Texas and established the Rancho Santa Margarita near present-day San Patricio. The family experienced many difficult times during an arduous political era in Texas, even leaving the rancho to escape upheaval from the war for independence from Spain. He returned to Texas in 1814 and settled closer to La Bahia. In 1824, his petition for an empresario grant was approved and he established Guadalupe Victoria which included people from a range of nationalities. In 1831, his colony was expanded to include most of modern Calhoun County west of Matagorda Bay. A port was established near present-day Port Lavaca on Lavaca Bay which provided the colony crucial access to trade and supplies, and established the area as a viable shipping link to future generations. Don Martin de Leon died in a cholera epidemic that swept the U.S. he is remembered as a pioneer in the settlement of the Texas gulf coast.

The Story
After Mexico won independence from Spain, it used the empresario system to settle Texas with loyal colonists, and in April 1824 Don Martín de León secured a grant—second in success only to Stephen F. Austin's. Born in Nuevo Santander and a former captain in the Spanish military, de León established the town of Guadalupe Victoria and, by 1831, a colony reaching across much of modern Calhoun County west of Matagorda Bay. A port near present-day Port Lavaca gave the colony vital access to trade and supplies.
Why it matters
De León was the only Mexican-born empresario to found a major Texas colony, a reminder that Tejano settlers helped build the Gulf Coast alongside Anglo-American newcomers.
The story behind this marker
AI contextThe era
In the early 1820s, the map of North America was being redrawn. Mexico had just won its independence from Spain, and the vast, thinly settled province of Texas was suddenly the young nation's responsibility to hold and populate. To do it, Mexico turned to the empresario system — granting ambitious individuals the right to bring in colonists in exchange for settling the land with loyal, productive citizens.
The Gulf Coast that these colonists faced was largely wilderness: open prairie, coastal bays, and a frontier that had already tested settlers through years of political turmoil. Carving farms, ranches, and towns out of this country was slow and risky work, and the wars and upheavals of the independence era had scattered more than one early family.
This was the world into which the empresario grants dropped like seeds. A successful colony needed people, land, and — above all — a way to move goods. On the central Gulf Coast, that meant access to the water, where a port could turn an isolated inland settlement into a place connected to the wider world of trade and supply.
People & events
At the center of this marker stands Don Martín de León. Born in Cruillas in Nuevo Santander — today's Tamaulipas — he joined the military around 1790 and rose to the rank of captain. In 1795 he married Doña Patricia de la Garza, and near the turn of the century the family moved to Texas, establishing the Rancho Santa Margarita. Those were hard, unsettled years; the family even left the rancho to escape the violence of the war for independence from Spain, returning to Texas in 1814.
His great opportunity came in 1824. On April 8 he applied to the provincial delegation at San Fernando de Béxar for an empresario grant, and just five days later it was approved. With it he founded the town of Guadalupe Victoria and drew in colonists of varied nationalities. In 1831 his colony was expanded to take in most of modern Calhoun County west of Matagorda Bay, and a port established near present-day Port Lavaca on Lavaca Bay gave the colony its vital link to trade and supplies.
His was among the most successful of all the Texas empresario ventures — second only to that of Stephen F. Austin. De León did not live to see how the region would grow: he died in a cholera epidemic, one of the sweeping outbreaks of the age, remembered as a pioneer of the Texas Gulf Coast.
Its place in the American story
De León's colony complicates the familiar story of how Texas was settled. The popular version centers on Anglo-American newcomers streaming in from the United States, but this Mexican-born captain founded and led a thriving colony of his own, planting a town and a port that helped define the central coast. Tejano settlers were not bystanders to the building of Texas — they were among its founders.
The empresario system itself was a bold experiment in nation-building, an attempt by a new Mexican republic to secure a distant frontier by inviting colonists to develop it. The mix of nationalities in de León's colony captures how genuinely multicultural this borderland was long before it became part of the United States.
And the port on Lavaca Bay proved to be more than a convenience for one colony. Establishing reliable coastal access laid down infrastructure that outlived its founder and shaped the region for generations — a reminder that the decisions of these early settlers still echo in the towns and shipping routes of the Texas coast today.
If you visit
You've come to the country de León helped open — the central Gulf Coast around Port Lavaca and Lavaca Bay, where his colony reached the water. Let the setting do the work: look out over the bay and imagine why a port here mattered so much, turning inland farms and ranches into a community connected to the trade of the wider world.
This is flat, open coastal Texas, big sky and salt air. Reading a marker like this is really an invitation to notice how much older the region's history runs than the modern towns suggest — a Spanish-born captain and his family were staking their future here two centuries ago.
It fits naturally into a heritage drive through Calhoun County and toward Victoria, the town de León founded as Guadalupe Victoria. Pair the two, and you can trace an empresario's colony from its coastal lifeline to its inland heart, and give the region's Tejano founders the attention the usual Texas story tends to skip.

Six Mile-Royal Community
Port Lavaca, TX
In December 1894 the Phillips Investment Company deeded land here to Josef Marek and John Drgac, and the settlement—soon called Marekville—drew Czech and German farmers with a bumper first cotton crop. A school rose in 1895 and a post office named Royal opened in 1905, while the enduring "Six Mile" name recalled that it was six miles to water from Port Lavaca. Though the post office closed in 1910, the farming community kept growing for generations.
Alsatian Immigration Through Lavaca Bay
Port Lavaca, TX
Empresario Henri Castro contracted in 1842 to bring European colonists to Texas, and the first—mostly German-speaking Alsatians—arrived through Galveston in 1843 before sailing on to Lavaca, later Port Lavaca. From there they set out overland to Medina County to found Castroville, though many succumbed to coastal fevers along the way. Ships continued through 1846, and by the time Castro's contract expired in 1847 he had carried more than 2,000 colonists to Texas, most of them through Lavaca Bay.
Zimmerman Cemetery
Port Lavaca, TX
This coastal graveyard, whose earliest marked burial dates to 1852, holds an unlikely thread of American military history. Buried here are John Gonzales and Joseph Mendez, natives of Spain who came to Indianola in 1858 as caretakers for a shipload of camels the U.S. Army had imported in its famous experiment to use the animals for frontier transport. The cemetery served the vanished port communities of Magnolia Beach and Indianola and took its name from the Zimmerman family, tied in by marriage.
Old Town Cemetery
Indianola, TX
On a ridge above Indianola Beach lies one of the burial grounds that served the bustling Gulf port of Indianola, a rival to Galveston before hurricanes wiped it off the map. Its oldest legible stone dates to 1851, and among those laid to rest here were German immigrants who arrived in the great migration of the 1840s. One grave belonged to Angelina Eberly, remembered as the heroine of the Texas Archives War, though storms and vandalism have since erased her marker and many others.
