Comprehensive Study Notes on Mexican Colonial History, Independence, and the Texas Revolution
Cortés, the Siege of Tenochtitlan, and the Tlaxcalan Alliance
The Trap at Tenochtitlan:
Following the death of the Aztec emperor Moctezuma on a rooftop while attempting to pacify his people, Hernán Cortés and his Spanish forces found themselves trapped inside a palace within the island city of Tenochtitlan.
The island geography presented a major tactical vulnerability, as there was no immediate avenue of retreat over Lake Texcoco.
The Aztecs placed the palace under direct siege, aiming to starve the Spanish forces into submission before destroying them upon exit.
The Escape Strategy:
While under siege, Cortés's men constructed large wooden bridges inside the palace complex, designed to span the gaps in the causeways that connected the island city to the mainland.
The Spanish waited for a severe thunderstorm to provide noise cover from thunder and rain to mask their movement.
The Spanish laid down the wooden bridges and began sneaking out of the city under cover of the storm.
The Cost of Retreat:
Midway through the escape, Aztec warriors detected the fleeing forces and launched a heavy assault.
Cortés lost approximately of his men in the bloody retreat, though he managed to escape the island with the surviving remnant.
Retreat to Tlaxcala:
The surviving Spanish forces retreated to Tlaxcala, the home of the Tlaxcaltecas—the primary regional rivals of the Aztec Empire.
Cortés had previously fought against the Tlaxcaltecas before securing a tentative alliance with them.
Although the Tlaxcaltecas possessed the power to finish off the severely diminished Spanish force, they chose instead to resupply, shelter, and re-arm Cortés, viewing him as a crucial tool to overthrow Aztec dominance.
In exchange for their military support, the Tlaxcaltecas secured heavy concessions, including promises of exemption from future imperial taxation and high status under the post-conquest order.
Land Grants, Social Stratification, and the Encomienda System
Conquistador Land Distribution:
Following the fall of Tenochtitlan, Cortés granted massive tracts of land to his conquistadors as the spoils of victory.
This established an enduring structural dynamic in Mexican history: a tiny percentage of the population came to possess the vast majority of the nation's land.
This distribution model contrasted sharply with British North America, where colonization was driven largely by small family farmers, working-class settlers, and religious dissidents sent away from the United Kingdom, preventing early hyper-concentration of land ownership.
Incentives for Spanish Settlers:
Joining the conquistadors offered lower-class Spanish men and common soldiers the ability to ascend to landed nobility (noblemen/lords) in the Americas.
This potential for social mobility and immense wealth generated a continuous influx of young Spanish men to the Americas for centuries.
The Encomienda System:
Form and Duration: Formally established for years, though it persisted informally in regional pockets across Mexico for decades.
Mechanism: Conquistadors (encomenderos) were exempt from direct personal taxation by the Spanish Crown. Instead, the Crown granted them the right to extract forced labor and tribute/taxes from indigenous populations living on assigned lands.
Reciprocal Obligations: In exchange for extracted labor, encomenderos were nominally required to provide military protection to indigenous communities and oversee their religious education and forced conversion to Catholicism.
Practical Reality: Functioned as an uncompensated forced labor system in agriculture and mining.
Indigenous Collaborators & Communal Farming:
To rule millions of people with minimal military personnel, the Spanish elevated high-ranking indigenous leaders to lower-tier noble status (such as descendants of Moctezuma retaining noble titles, including the Ducal seat of Moctezuma in Spain).
These native elites facilitated tax collection, legitimized Spanish authority, and maintained local order.
Communal Farming System (Ejidos): Indigenous populations maintained a system of shared, communal agricultural plots rather than individual private property. Entire communities were collectively responsible for farming these shared lands, preserving a degree of local self-governance. This communal framework served as the direct precursor to the ejido system revived during the Mexican Revolution.
Racial Dynamics, Demographic Collapse, and the Caste System
Origins of Racial Intermixing:
Racial mixing began immediately upon Cortés's arrival at Veracruz, where indigenous leaders traded women as wives to Spanish officers to cement political treaties.
Because Spanish colonization was driven by male military personnel rather than family units, sexual relationships and strategic marriages were treated as spoils of conquest.
Cortés's interpreter fathered children with an indigenous woman, and Cortés himself fathered at least children with at least indigenous women.
Social Class Hierarchy:
Peninsulares: Elites born directly on the Iberian Peninsula in Spain. They monopolized top colonial administrative and religious posts. The Spanish Crown intentionally appointed Peninsulares rather than American-born elites for over years to ensure governance remained in the hands of individuals strictly loyal to Spain who had not adopted a distinct American identity.
Criollos: Individuals of Spanish descent born in the Americas. Recognized by the Catholic Church as legitimate descendants of sanctified marriages between conquistadors and Spanish or indigenous wives. While wealthy and landed, they were systematically excluded from the highest government offices.
Mestizos: Individuals of mixed European and indigenous heritage born out of wedlock, unacknowledged as legitimate by the Catholic Church or Spanish Crown. Occupying a legal limbo initially, mestizos grew over centuries to become the single largest demographic group in Mexico.
Indigenous Populations: Occupied the lowest formal tier of the imperial hierarchy, subjected to forced labor and tribute obligations.
Demographic Collapse:
European diseases (primarily smallpox and plague) decimated the indigenous population, reducing it to approximately of its pre-conquest size.
The deaths of elders and community leaders severed traditional oral lines of history, culture, and governance, creating a social and spiritual vacuum filled by Spanish institutions.
Imperial Administration and Mercantilism in New Spain
Territorial Extent of New Spain:
The Spanish Crown established the Viceroyalty of New Spain (Virreinato de Nueva España) to administer its northern empire.
At its peak, the viceroyalty spanned from Panama in the south, north through Central America and modern Mexico, and deep into modern US territory (including California, Texas, New Mexico, Arizona, Utah, and parts of Colorado).
Population Disparities: While the Central Valley of Mexico was densely populated, the far northern borderlands and far southern reaches remained extremely sparsely populated.
Mercantilist Economic Extraction:
The colonial economy was organized strictly around mercantilist principles to extract wealth for Spain.
Extensive road networks were constructed to transport gold and silver from northern mines down to Mexico City and the coastal port of Veracruz for shipment to Spain.
New Spain was forbidden from trading with other European powers or self-manufacturing goods that competed with Spanish industries; the colony was forced to export raw materials to Spain and import finished goods exclusively from Spanish merchants.
The Role of the Catholic Church and Religious Syncretism
Evangelization and Imperial Control:
Following the Spanish Reconquista and the rise of the Spanish Inquisition, the Catholic Church operated in tandem with the conquistadors and colonial state.
To symbolize spiritual dominance, Catholic cathedrals were routinely constructed directly on top of destroyed indigenous temples and palaces, utilizing the very stones of those demolished structures.
While some clergy members (such as Bartolomé de Las Casas) publicly denounced Spanish abuses, the Church functioned primarily as an institution of imperial control.
Religious Syncretism:
To overcome language barriers and convert surviving indigenous populations, the Catholic Church co-opted local deities and spiritual practices.
Local indigenous gods were recast as Catholic saints or localized manifestations of religious figures, allowing native populations to maintain traditional worship within a Catholic framework.
This produced localized, highly distinct regional religious traditions across Mexico that persist today (including unique religious iconography utilized by modern drug cartels).
Institutional Influence and Record-Keeping:
The Catholic Church became the single largest landowner in New Spain.
It maintained absolute institutional control over public life, acting as the primary keeper of vital records (births, marriages, and deaths) far more comprehensively than the secular government.
Mid-18th Century Cracks: Bourbon Reforms and Rising Resentment
Imperial Stability:
Spanish colonial rule functioned with relative stability for over years—substantially longer than the United States has existed ( years).
External Pressures:
By the mid-, cracks formed due to the growing commercial and naval power of Great Britain, which was accumulating vast wealth through free trade policies.
Compounding pressures from France forced the Spanish Crown to modernize its imperial system.
The Bourbon Reforms:
A progressive series of administrative, economic, and military laws enacted by the Spanish Crown starting in the mid-.
Economic Goal: Increase colonial productivity and tax yields by relaxing strict mercantilist barriers and permitting controlled free trade between Spanish colonies.
Political and Military Goal: Establish centralized control over colonial administrations and expand military presence to prevent British territorial encroachment in the Americas.
Colonial Backlash:
Increased military presence and aggressive state collection created widespread friction, mirroring the colonial chafing experienced in the British Thirteen Colonies (though the initial Mexican response was more muted).
Criollo Resentment: Over centuries, Criollos had gradually filled intermediate administrative roles within the empire. The Bourbon Reforms systematically stripped Criollos of these positions, re-assigning administrative authority exclusively to Spanish-born Peninsulares and reducing Criollos back to their reduced political status of the .
Taxation: Higher tax rates were imposed across all colonial sectors to extract revenue more efficiently.
Secularization, the Expulsion of the Jesuits, and Early Rebellions (1767)
Crown Encroachment on the Church:
The Spanish Crown attempted to secularize administration in New Spain, seeking separation of church and state functions to diminish the Church's political leverage.
Expulsion of the Jesuits ():
In , the Crown expelled the Jesuit order from Mexico due to their political independence, wealth, and open critiques of royal policy.
The expulsion deeply outraged the populace and sparked the first major wave of widespread, violent rebellions against Spanish rule in centuries.
Suppression:
The Spanish military ruthlessly crushed these regional rebellions without mercy, leaving New Spain in a state of heightened political tension leading into the .
The Imperial Crisis of 1808: Napoleonic Invasion of Spain
French Invasion:
In , Napoleon Bonaparte invaded the Iberian Peninsula, conquered Spain, forced the Spanish monarchs to abdicate, and installed his brother Joseph Bonaparte on the Spanish throne.
Crisis of Legitimacy:
The sudden subjection of Spain to French rule fundamentally destabilized the colonial hierarchy in the Americas.
While Mexican elites generally tolerated Spanish rule, being governed by a French puppet monarch was considered entirely illegitimate.
Elite Fractures: Criollos declared French authority void and advocated for self-governing local juntas until the Spanish monarch was restored. Peninsulares argued for playing along with the new administration to preserve the existing order. This divide created the wedge that made independence possible.
Dissolution of Government ():
On September 15, , the existing Spanish-appointed government over the Viceroyalty of New Spain was forcibly dissolved and replaced by a pro-Napoleonic regime, accelerating underground revolutionary activity.
The Grito de Dolores and Miguel Hidalgo’s Revolt (1810–1811)
The Cry of Dolores ():
On September 16, (the actual Mexican Independence Day, distinct from Cinco de Mayo), Father Miguel Hidalgo y Costilla, a Catholic priest in the town of Dolores, initiated the independence movement.
Hidalgo rang his church bells to assemble his parish, delivering an impassioned, fiery rally speech (the Grito de Dolores, akin to William Wallace's speeches depicted by Mel Gibson in Braveheart).
He mobilized thousands of indigenous peasants, mestizos, and local villagers into an armed revolutionary force.
Defeat and Martyrdom:
Hidalgo was an untrained military strategist, leading a poorly equipped and undisciplined mass movement.
In , royalist forces captured Hidalgo. He was excommunicated by the Catholic Church and executed by Spanish military authorities.
His death transformed him into a permanent martyr for Mexican independence.
The Fitful Independence Struggle and Iturbide’s Defection (1810–1821)
Nature of the War:
Unlike the structured progression of the American Revolutionary War, Mexican independence was fought in fitful cycles over years (), characterized by violent regional uprisings, severe lulls, and royalist counter-insurgency.
Guerrilla leaders like José María Morelos and Vicente Guerrero maintained regional rebellions across southern Mexico.
Failed French Liberalization:
Napoleon attempted to pacify New Spain by introducing constitutional voting rights for colonial representatives. However, the populace used elections to vote overwhelmingly for secessionist candidates, forcing the regime to roll back political reforms.
Spread of Revolutionary Ideology:
Following Napoleon's defeat in and the restoration of the legitimate Spanish monarchy, rebellions persisted.
The concept of independence had spread irrevocably throughout the population (functioning like a virus implanted in the mind, as in the film Inception, or like "toothpaste out of the tube").
The Turning Point of :
By , royalist forces had largely suppressed the armed insurgency, making independence appear dead.
In , a liberal military coup in Spain seized control of the Spanish government and forced liberal constitutional restrictions on the monarch.
This political shift deeply alarmed the conservative landed elites and Criollos in Mexico, who viewed a liberal Spanish government as a threat to their land ownership, Church privileges, and colonial social order.
Agustín de Iturbide’s Defection:
The Spanish government assigned its top general, Agustín de Iturbide, to crush Vicente Guerrero’s remaining insurgent forces.
Exhibiting a classic principal-agent problem, Iturbide recognized that conservative Mexican elites desired separation from liberal Spain.
Iturbide forged a secret pact with Guerrero and the rebels (analogous to Darth Vader forming an alliance with Han Solo to defeat the Emperor).
Iturbide pledged the entire royalist army to the cause of independence in exchange for political leadership.
Plan de Iguala and Independence ():
Plan de Iguala: A compromise plan stipulating that Mexico would become an independent constitutional monarchy, guaranteeing protection for the Catholic Church and political equality between Criollos and Peninsulares.
With the defected royalist military behind him, Spanish authority in Mexico City completely dissolved.
In , Iturbide marched unopposed into Mexico City, securing independence with virtually no final bloodshed.
Spain lacked the military resources to contest the loss, although it refused to formally recognize Mexican independence until the mid-. This collapse triggered a chain reaction that ended Spanish control throughout Latin America.
Post-Independence Instability: Ideological Fractures and Caudillismo (1821–1876)
Fifty Years of Political Chaos:
From , Mexico suffered from severe political instability, undergoing separate changes of government across years (averaging roughly new government per year).
Unlike the American colonists, who possessed centuries of local self-governance experience, Mexican society had no prior experience in democratic self-rule.
Ideological Divisions:
Liberals: Sought to model Mexico after the United States, advocating a secular liberal democracy, state rights, the removal of Catholic Church influence, and the political disenfranchisement of traditional Criollo elites.
Conservatives: Favored a centralized state structure modeled on the old Spanish empire, protecting Catholic Church privileges, military exemptions, and elite property rights.
Centralists vs. Federalists: Centralists demanded absolute control from Mexico City; Federalists fought for an autonomous US-style state model.
Caudillos: Regional military warlords commanding private armies who routinely launched coups to seize the national government in Mexico City.
The First Mexican Empire and Imperial Execution ():
In May , Agustín de Iturbide proclaimed himself Emperor of Mexico.
Faced with immediate military uprisings from regional caudillos, Iturbide was forced to abdicate in and flee into exile. Upon attempting to return in , he was captured and executed.
Territorial Secessions ():
In , Mexican states such as Oaxaca, Yucatán, Jalisco, and Zacatecas declared themselves autonomous states, refusing centralized commands from Mexico City and raising private militias.
In , the southern territory of Central America (including Guatemala) permanently seceded from Mexico (a historical reality that remains a lighthearted point of contention, such as joking with a Guatemalan spouse that Guatemala was originally part of Mexico).
Northern Borderlands, Anglo Settlement, and Tensions in Texas
Geographic Vulnerabilities:
Mexico's northern territories (modern Texas, California, New Mexico, Arizona, Nevada, Utah, and parts of Colorado) were vast and sparsely populated due to a severe lack of water infrastructure (prior to modern developments like the Hoover Dam).
Mexican leaders grew increasingly alarmed by the rapid westward expansion and Manifest Destiny doctrine of the United States.
Colonization Policies:
To construct a human buffer against US encroachment, Spain (and later independent Mexico) initiated policies to colonize Texas.
Moses Austin: An Anglo-American living in Missouri (then technically Spanish territory, making him a subject of the Spanish Crown despite being a "gringo's gringo"), petitioned for a grant to establish an Anglo colony in Texas.
Moses Austin died in ; his son, Stephen F. Austin ("Stone Cold Steve Austin"), inherited the colonization enterprise.
The newly independent Mexican government honored Austin's contract, granting generous land terms, low taxes, and temporary exemptions regarding anti-slavery laws to keep the settlers loyal to Mexico.
Escalation of Texas Friction:
Anti-Slavery Decree: Mexico outlawed slavery nationwide in . While Texas received a temporary exemption, Anglo settlers feared slavery would soon be banned forcefully.
Tax Hikes: Mexico began increasing tax rates on Texas commerce.
Mid- Restrictions: Mexico enacted laws prohibiting the further importation of slaves into Texas and banning all immigration from countries adjacent to Mexico (specifically targeting Anglo-Americans from the US).
Failed Internal Migration: Mexican government efforts to incentivize interior citizens from Mexico City or southern states to colonize Texas failed, as citizens refused to relocate to the harsh northern frontier.
Austin's Threats: Stephen F. Austin began sending threatening correspondence to Mexican state governors, warning that Mexico must sell Texas to the United States or face an armed colonial revolt.
Santa Anna, the Texas Revolution, and the Siege of the Alamo (1835–1836)
Rise of Santa Anna ():
General Antonio López de Santa Anna, a centralist military leader, seized power in Mexico in .
Santa Anna resolved to crush Texan defiance, end local autonomy, and re-establish central state rule, declaring Mexican sovereignty over Texas non-negotiable.
Outbreak of the Texas Revolution ():
In November , Texan delegates organized a formal convention, declared that Mexico had breached its constitutional contract, and launched an armed rebellion.
Texan forces militarily captured San Antonio and expelled Mexican royalist garrisons from the state.
Siege of the Alamo ():
Santa Anna personally led a military expedition north in January to forcibly restore Mexican authority.
In February , Santa Anna's army laid siege to approximately Texan rebels occupying the Alamo mission in San Antonio.
Declaration of Independence: On March 2, , Texas formally declared its independence from Mexico.
Fall of the Alamo (): On March 6, , Santa Anna's forces stormed the Alamo, killed the defenders during the assault, and executed all surviving prisoners.
Strategic Failure of Execution:
Santa Anna ordered the mass executions to send an unequivocal warning to Texas rebels and the United States government that Mexico would fight ruthlessly to prevent territorial loss ("don't fuck with Mexico").
The mass execution proved to be a catastrophic strategic mistake; rather than terrifying the opposition into submission, it provided a galvanizing battle cry ("Remember the Alamo") that fueled Texan resistance and led directly to Santa Anna's subsequent military defeat.
