Coahuila y Tejas (Coahuila and Texas)
Years: 1827 - 1833
Coahuila y Tejas (Coahuila and Texas) is one of the constituent states of the newly established United Mexican States under its 1824 Constitution.
It has two capitals: first Saltillo, and then Monclova.
For administrative purposes, the state is divided into three districts: Béxar, comprising the area covered by Texas, Monclova, comprising northern Coahuila, and Río Grande Saltillo, comprising southern Coahuila.The state remains in existence until the adoption of the 1835 "Constitutional Bases", whereby the federal republic is converted into a unitary one, and the nation's states, (estados), are turned into departments (departamentos).
The State of Coahuila y Texas was split in two and became the Department of Coahuila and the Department of Texas.
The latter eventually secedes and becomes the independent Republic of Texas, which is today the state of Texas within the United States of America.Both Coahuila and Texas secede from Mexico because of Santa Anna's attempts to centralize the government, with Texas forming the Republic of Texas and Coahuila joining with Nuevo León and Tamaulipas to form the short-lived Republic of the Rio Grande.

Northern North America (1684–1827 CE); Empires Contested, Nations Born, Frontiers Pushed
Geography & Environmental Context
Northern North America includes the modern United States and Canada, excluding the West Indies. It is divided into three subregions:
-
Northeastern North America: east of 110°W, from New England and the Maritimes through the Great Lakes and Hudson Bay to Virginia, the Carolinas, most of Georgia, and the Mississippi Valley above Little Egypt.
-
Northwestern North America: west of 110°W, from Alaska and the Yukon to the Pacific Northwest and northern California north of the Gulf line.
-
Gulf and Western North America: the wedge south of the Montana diagonal, encompassing the plantation South, the Mississippi Valley below Illinois’ Little Egypt, the Plains, the Southwest, and California south of the Oregon border.
Together, these lands embraced a mosaic of boreal forest, prairie, Appalachian highlands, arid plains, subtropical deltas, and Pacific fjords. Each subregion developed distinct lifeways, but all were drawn into the same imperial rivalries and revolutionary transformations.
Climate & Environmental Shifts
The Little Ice Age persisted into the 18th century, bringing harsh winters to the northeast, erratic salmon and root harvests in the northwest, and drought cycles to the Southwest. Hurricanes battered the Gulf coast, while floods shaped the Mississippi delta. Resource pressures mounted: beaver populations declined from overtrapping, forests receded around port towns and plantations, and horse herds spread across the Plains.
Subsistence & Settlement
-
Indigenous nations maintained diverse economies: maize horticulture in the northeast and southeast, bison hunting on the Plains, salmon fisheries along Pacific rivers, and seal and whale hunting in the Arctic.
-
Colonial settlements took different forms: French Canada and Louisiana, Spanish missions in the Southwest and California, British seaboard colonies, and Russian posts in Alaska.
-
The United States, born of revolution, expanded westward into Kentucky, Tennessee, and the Ohio Valley, while Loyalists and Acadians reshaped Canada’s demography.
Technology & Material Culture
Indigenous technologies — birchbark canoes, snowshoes, horse gear, cedar plankhouses, irrigation systems — persisted alongside European imports: muskets, iron tools, plows, mills, sailing ships, and missions. Hybrid cultures emerged, such as Métis in the fur trade, African-descended Gullah in the Carolinas, and Spanish-Indian ranching lifeways in the Southwest.
Movement & Interaction Corridors
-
Rivers: the St. Lawrence, Great Lakes, Mississippi, and Columbia were arteries of commerce and war.
-
Maritime networks: Atlantic ports linked to Europe, the Caribbean, and Africa; Gulf and Pacific ports tied into global markets.
-
Overland corridors: mission trails, fur brigades, and horse trade networks tied regions together.
-
Migration: enslaved Africans carried to the South, European immigrants to the seaboard and interior, Loyalist refugees to Canada, and Indigenous nations displaced westward.
Cultural & Symbolic Expressions
Indigenous diplomacy — wampum belts, council fires, potlatch ceremonies, and Green Corn rituals — remained central. European religions spread: Catholicism in French and Spanish zones, Protestantism in the British colonies, syncretic traditions among African and Native peoples. Symbols of sovereignty proliferated: forts, flags, treaties, missions, and plantations marked territorial claims.
Environmental Adaptation & Resilience
Indigenous nations diversified subsistence, shifting to fur trapping, mounted bison hunting, or blending ritual with Catholic observance. Colonists adapted to hurricanes, droughts, and floods with new architecture, irrigation, and crop rotations. Food storage, trade alliances, and hybrid practices allowed resilience in a volatile climate.
Political & Military Shocks
-
Imperial wars: Nine Years’ War, Queen Anne’s War, and the Seven Years’ War reshaped borders and alliances.
-
Revolutions: The American Revolution created the United States; the Haitian Revolution reverberated through the Gulf; Indigenous uprisings, from Tecumseh’s confederacy to Pueblo resistance, challenged colonial regimes.
-
Territorial transfers: Louisiana Purchase (1803), Florida cession (1821), Russian America consolidations in Alaska.
-
War of 1812: Britain and the U.S. contested Great Lakes and Gulf coasts, leaving Native confederacies weakened.
Transition
Between 1684 and 1827, Northern North America was transformed from a patchwork of Indigenous nations and rival empires into a continental stage of settler republics, expanding frontiers, and Indigenous dispossession. The fur trade, cod fisheries, plantations, and salmon runs tied its subregions into global markets, while revolution and war redrew its maps. By 1827, the United States was pushing across Appalachia, Canada remained in Britain’s orbit, Russian America and Spanish missions dotted the Pacific, and Native nations, though battered, continued to anchor economies and cultures from the Arctic to the Gulf.
Gulf and Western North America (1684–1827 CE): Missions, Revolts, and Expanding Frontiers
Geographic & Environmental Context
The subregion of Gulf and Western North America includes Mississippi, Louisiana, Arkansas, Texas, Oklahoma, Kansas, New Mexico, Colorado, Wyoming, Arizona, Utah, Nevada, nearly all of California (except the far northwest), nearly all of Florida (except the extreme northeast), southwestern Georgia, most of Alabama, southwestern Tennessee, southern Illinois, southwestern Missouri, most of Nebraska, southeastern South Dakota, southern Montana, southern Idaho, and southeastern Oregon. Anchors included the lower Mississippi delta, the Rio Grande valley, the Sonoran and Chihuahuan deserts, and the California coast.
Climate & Environmental Shifts
The Little Ice Age persisted into the 18th century, bringing cooler winters and drought cycles to the Southwest. Hurricanes periodically devastated Gulf settlements. California’s Mediterranean climate sustained oak groves, salmon runs, and estuaries, but aridity in deserts stressed irrigation systems.
Subsistence & Settlement
-
Puebloans continued irrigated farming of maize, beans, and squash, though Spanish tribute demands strained resources.
-
Navajo and Apache adopted horses and expanded raiding economies.
-
Plains peoples increasingly relied on mounted bison hunting, reshaping lifeways.
-
California tribes harvested acorns, fish, and game; in the late 1700s, Spanish missions sought to convert and settle them under forced labor.
-
Spanish colonists established missions, presidios, and ranches in Florida, Texas, New Mexico, Arizona, and California; French Louisiana (founded 1699) grew around New Orleans and the Mississippi delta. After 1763, Louisiana passed to Spain, then back to France, and was sold to the United States in 1803.
Technology & Material Culture
Adobe pueblos, irrigation canals, and kivas persisted. Indigenous horse culture flourished on the Plains. Spanish introduced stone churches, presidios, iron tools, firearms, and livestock. California’s missions of Junípero Serra embodied a distinctive architectural and cultural imprint.
Movement & Interaction Corridors
-
Spanish missions and presidios extended along the Rio Grande, into Texas, and along California’s coast.
-
French traders in Louisiana used the Mississippi as a highway of exchange.
-
Indigenous horse trade moved animals across the Plains.
-
The Gulf Coast and Caribbean funneled silver, hides, and grain into global markets.
Cultural & Symbolic Expressions
-
Pueblo rituals of kachina dances endured underground after the Pueblo Revolt of 1680, the largest Indigenous uprising of colonial North America.
-
Southeastern Green Corn ceremonies persisted despite missionization.
-
California tribes blended Indigenous ritual with Catholic festivals in mission contexts.
-
Spanish Catholicism dominated mission landscapes; French Catholic culture shaped Louisiana.
Environmental Adaptation & Resilience
Indigenous communities resisted or adapted to mission labor, relocated settlements, and integrated horses for mobility and hunting. Colonists diversified economies through ranching, farming, and coastal trade. Hurricanes, droughts, and epidemics tested resilience, but hybrid lifeways sustained survival.
Transition
By 1827 CE, Gulf and Western North America was a patchwork: Spanish missions, French legacies, Indigenous nations, and expanding U.S. frontiers. Horses, guns, and new crops had remade societies, while epidemics and conquest inflicted loss. Yet resilience persisted in Pueblo villages, Plains bison hunts, and California’s tribal memory.
The Mexican War for Independence had severed the control that Spain had exercised on its North American territories in 1821 and the new country of Mexico had been formed from much of the lands that had comprised New Spain, including Spanish Texas.
The 1824 Constitution of Mexico had joined Texas with Coahuila to form the state of Coahuila y Tejas.
The Congress had allowed Texas the option of forming its own state "'as soon as it feels capable of doing so.'"
The same year, Mexico had enacted the General Colonization Law, which enabled all heads of household, regardless of race or immigrant status, to claim land in Mexico.
Mexico has neither manpower nor funds to protect settlers from near-constant Comanche raids and it hopes that settlers can control the raids.
The government has liberalized its immigration policies, allowing for settlers from the United States to immigrate to Texas.
The first empresarial grant, which had been made under Spanish control to Moses Austin, had been passed to his son Stephen F. Austin, whose settlers, known as the Old Three Hundred, had settled along the Brazos River in 1822.
The grant had later been ratified by the Mexican government.
Twenty-three other empresarios bring settlers to the state, the majority from the United States of America.
The new state constitution for the Mexican state of Coahuila y Tejas, ratified on March 11, includes a phasing-out of slavery in its Article 13, which declares that "From and after the promulgation of the constitution in the capital of each district, no one shall be born a slave in the state, and after six months the introduction of slaves under any pretext shall not be permitted."
The prohibition of importing enslaved people from the United States will be lifted when Texas declares independence in 1836, and the Republic of Texas Constitution will provide specifically that Africans and "the descendants of Africans" will not be considered "citizens of the republic".
Neither the Mexican national constitution nor the 1827 constitution for the state of Coahuila y Tejas grants trial by jury and the right of bail, omissions that the Anglo-American colonists in Texas find unacceptable, as so the requirement that the mostly Protestant settlers convert to Roman Catholicism.
In 1821 in an effort to colonize and populate Texas, the Spanish commander in Monterrey had granted a concession to a United States pioneer, Moses Austin, to settle the area under the Roman Catholic faith.
Land could be acquired for a nominal charge of US$0.25 per hectare, and soon colonists from the United States started to pour into the area.
By 1835 they outnumber the Mexicans, four to one.
Texas has no autonomous government and is politically attached to the state of Coahuila.
Most Mexicans begin to fear the incursions by North Americans and the possibility of losing Texas to the United States.
Restrictions had been placed on the future immigration of colonists from the United States, and slavery had been abolished in 1829 in the hope of discouraging United States southerners from moving into the area.
In 1835 Santa Anna marches north in the direction of San Antonio with an army of three thousand men.
He reaches San Antonio in March 1836 and learns that about one hundred and fifty armed Texans have taken refuge at an old Franciscan mission, called the Alamo
He lays siege to the mission for several days before the final attack on March 6, 1836.
The Mexican force takes the mission the next day, killing all but five of the defenders in battle (the five prisoners are later executed).
On March 23, the Texan town of Goliad is surrounded by Mexican forces, who compel the Texan commander in charge to surrender.
On express orders from Santa Anna, three hundred and sixty-five prisoners were executed.
The events at the Alamo and at Goliad stir strong anti-Mexican sentiment in the United States.
Volunteer fighters pour into Texas to stage a decisive blow against Santa Anna.
The Mexican commander in chief and his army are ambushed and roundly defeated near the San Jacinto River by a force commanded by Sam Houston on April 21.
Santa Anna, who had fled the scene of the battle, is captured by the Texans two days later.
Santa Anna's efforts to exert central authority over the English-speaking settlements in the northern state of Coahuila-Tejas eventually collide with the growing assertiveness of the frontier population that described itself as Texan.
Austin therefore travels to Mexico City in July 1833 with a petition asking for separate statehood from Coahuila, a better judicial system, and the repeal of the April 6 law that had caused the first Anahuac and Velasco Disturbances (1832), among other things.
After meeting with Farías, Austin’s requests are all approved except for separate statehood, which requires a population of eighty thousand before it can be granted, and Texas has only thirty thousand.
Despondent over not getting Texas separated from Coahuila, Austin writes an angry letter to a friend, which seems to encourage rebellion.
Mexican officials intercept the letter, and Austin is arrested for sedition.
He will spend eighteen months in prison.
