Why This Matters

The Spanish conquest of Mexico wasn't a single event—it was a complex web of ambition, rivalry, alliance-building, and brutal violence that transformed an entire hemisphere. When you study these conquistadors, you're being tested on more than names and dates. You need to understand how colonial power was established, why indigenous alliances proved decisive, and what internal conflicts reveal about Spanish imperial ambitions. These figures demonstrate key concepts like the role of disease and technology in conquest, the importance of indigenous agency, and the ways colonial administration evolved from military campaigns to bureaucratic control.

Don't just memorize who did what. Know what each figure illustrates about the mechanisms of conquest—whether that's strategic alliance-building, the violence of initial contact, the competition among conquistadors themselves, or the transition from conquest to colonial governance. FRQs often ask you to analyze how Spain established control, not simply that it did. These figures are your evidence.


Strategic Leadership and Alliance-Building

The fall of the Aztec Empire wasn't inevitable—it required calculated diplomacy with indigenous groups who had their own reasons to oppose Mexica dominance. The conquistadors who succeeded understood that military force alone couldn't topple Tenochtitlan.

Hernán Cortés

  • Led the 1519-1521 expedition that culminated in the fall of the Aztec Empire—the defining moment of Spanish conquest in Mesoamerica
  • Formed critical alliances with the Tlaxcalans and other indigenous groups, demonstrating that conquest depended on exploiting existing political rivalries
  • Captured Moctezuma II and founded Mexico City on Tenochtitlan's ruins, symbolizing the replacement of indigenous power with Spanish colonial authority

Gonzalo de Sandoval

  • Served as Cortés's most trusted military commander—his loyalty helped maintain cohesion during the chaotic siege of Tenochtitlan
  • Led post-conquest campaigns against indigenous groups resisting Spanish control, extending dominion beyond the Valley of Mexico
  • Became governor of New Spain's central province, representing the transition from military conquest to administrative rule

Compare: Cortés vs. Sandoval—both were essential to the conquest's success, but Cortés embodied strategic vision and political maneuvering while Sandoval represented loyal military execution. If an FRQ asks about how the conquest succeeded, Cortés shows alliance-building; Sandoval shows sustained military pressure.


Violence and Coercion as Colonial Tools

Conquest was not a negotiation—it was enforced through systematic violence that terrorized indigenous populations into submission. These figures illustrate how brutality functioned as deliberate policy, not merely individual cruelty.

Pedro de Alvarado

  • Commanded the Toxcatl Massacre (1520)—the unprovoked slaughter of Aztec nobles during a religious festival that triggered the Noche Triste uprising
  • Served as Cortés's lieutenant before becoming governor of Guatemala, where he replicated conquest violence against Maya populations
  • Exemplifies how conquistador brutality destabilized indigenous societies while simultaneously provoking fierce resistance

Nuño Beltrán de Guzmán

  • Governed New Galicia with notorious cruelty—his oppressive rule became so extreme that even Spanish authorities eventually removed him
  • Led western Mexican expeditions characterized by enslavement and exploitation of indigenous peoples, prioritizing extraction over sustainable colonization
  • Represents the darker excesses of conquest that prompted reformers like Bartolomé de las Casas to advocate for indigenous protections

Compare: Alvarado vs. Guzmán—both employed extreme violence, but Alvarado's brutality occurred during active conquest while Guzmán's continued during supposed peacetime governance. This distinction matters for understanding how violence transitioned from military tactic to administrative policy.


Internal Rivalries and Competing Ambitions

The conquistadors weren't a unified force—they competed fiercely for glory, wealth, and royal favor. These conflicts reveal that Spanish colonialism was as much about intra-European power struggles as indigenous subjugation.

Diego Velázquez de Cuéllar

  • Governor of Cuba who commissioned Cortés's expedition—then attempted to revoke it when he feared losing control of potential riches
  • Sent Pánfilo de Narváez to arrest Cortés, demonstrating how colonial rivalries could undermine Spanish military efforts at critical moments
  • Represents the competitive structure of Spanish imperialism, where individual ambition often clashed with coordinated conquest

Pánfilo de Narváez

  • Led the failed 1520 expedition to capture Cortés—his defeat actually strengthened Cortés by providing additional soldiers and supplies
  • His capture by Cortés's forces illustrates how internal Spanish conflicts could inadvertently consolidate power for successful conquistadors
  • Later died during the disastrous Florida expedition, showing how conquistador ambitions frequently ended in failure beyond Mexico

Cristóbal de Olid

  • Initially served under Cortés before attempting to establish independent control in Honduras—a betrayal that ended in his execution
  • His rebellion against Cortés demonstrates that conquistador loyalty was conditional, based on perceived opportunities for personal gain
  • Contributed to Central American exploration before his treachery, showing how expansion and internal conflict occurred simultaneously

Compare: Velázquez vs. Olid—both challenged Cortés's authority, but Velázquez operated through official channels from Cuba while Olid attempted direct rebellion in the field. These different strategies for challenging conquistador power both failed, reinforcing Cortés's dominance.


Expansion Beyond the Aztec Core

The conquest of Tenochtitlan was just the beginning—Spanish ambitions extended throughout Mesoamerica, encountering diverse indigenous civilizations with varying capacities for resistance.

Francisco de Montejo

  • Led the prolonged conquest of the Yucatán Peninsula (1527-1546)—a campaign that took nearly two decades due to fierce Maya resistance
  • Faced decentralized Maya political structures that made conquest far more difficult than the centralized Aztec Empire
  • Established Spanish settlements that became foundations for colonial Yucatán, though Maya resistance continued for centuries

Juan de Grijalva

  • Conducted the 1518 coastal expedition that first mapped Mexican shores and confirmed rumors of wealthy civilizations inland
  • Gathered intelligence on Aztec trade networks and resources, providing crucial information that shaped Cortés's subsequent invasion
  • Represents the reconnaissance phase of conquest—exploration that preceded military campaigns and informed strategic planning

Compare: Montejo vs. Grijalva—Grijalva explored and gathered information without attempting conquest, while Montejo committed to full military subjugation. This contrast illustrates the different phases of Spanish expansion: reconnaissance, then conquest, then colonization.


Chronicling the Conquest

Our understanding of these events depends heavily on accounts written by participants—sources that require critical analysis of perspective and motivation.

Bernal Díaz del Castillo

  • Authored "The True History of the Conquest of New Spain"—a detailed eyewitness account written decades after the events to correct what he saw as inaccuracies
  • Participated as a common soldier under Cortés, offering perspectives different from official accounts that glorified leadership
  • His chronicle reveals conquistador motivations, internal conflicts, and interactions with indigenous peoples—essential primary source material for understanding the conquest

Compare: Díaz del Castillo vs. Cortés's letters—both provide firsthand accounts, but Cortés wrote to justify his actions to the Spanish crown while Díaz wrote to ensure common soldiers received credit. Analyzing these differing perspectives is exactly what document-based questions require.
