The conquest of the Mexica appears in two irreconcilable narratives: one where Spanish military superiority made indigenous defeat inevitable (structure-as-destiny), and one where Marina's translation, Tlaxcaltec alliance decisions, and Moctezuma's pragmatism made victory contingent on specific human choices (agency-as-determinative). These narratives feel opposed. They describe the same phenomenon from different analytical vantage points.
Marina did not freely choose to translate — she was enslaved, property, possessed no formal right to refuse. Yet her translation was absolutely essential; without it, Spanish conquest failed or was dramatically delayed. Moctezuma did not freely choose the institutional structures he inherited — he inherited calpolli organization, tlatoani role, xiuhpohualli calendar that framed historical time. Yet his decisions about how to navigate those structures determined whether Spanish invasion became negotiated subordination or catastrophic collapse. Tlaxcaltec leadership did not freely choose whether Spanish existed or whether Spanish military posed an unprecedented threat. Yet their choice to ally with Spanish rather than with Mexica was the pivotal decision that broke what would have been stronger indigenous coalescence.
The paradox dissolves when you recognize: agency and structure are not opposites. Agency is the capacity to make meaningful choices within structural constraints. Structure is the set of options available, the rules of the game, the prior decisions that create the field on which present choices occur. Neither determines outcomes alone. Together they produce history.
Spanish military technology (structure: steel, horses, firearms) created a military advantage (structure: Spanish soldiers could inflict disproportionate casualties). This advantage was real, measurable, consequential. It did not make Spanish victory inevitable. It made Spanish victory more likely if indigenous peoples did certain things (faced Spanish forces in open field, did not form strong coalitions, engaged Spanish in repeated direct combat). The structure constrained the problem space; it did not determine the solution.
Marina operated within structural constraints: she was enslaved, female, possessed knowledge Spanish valued (linguistic ability), and faced death if she was useless (structure: her life depended on usefulness). Within those constraints, she made a consequential choice: to translate in ways that constructed diplomatic space rather than escalated confrontation. She could have translated Spanish threats in inflammatory ways, triggering panic. She chose differently. That choice shaped how indigenous leadership understood Spanish arrival.
Moctezuma operated within structural constraints: he inherited institutions that had succeeded for a century (structure: calpolli organization, tributary networks, xiuhpohualli calendar), he faced intelligence that did not cohere (structure: Spanish could be gods, could be invulnerable, could be mortal men; sources contradicted), he faced a problem with no precedent (structure: no previous Spanish invasion provided template for response). Within those constraints, he chose a negotiating strategy over immediate total mobilization. That choice made indigenous collapse contingent on Spanish ability to navigate indigenous alliance structures (which Cortés eventually did through the Tlaxcaltec).
Tlaxcaltec leadership operated within structural constraints: they faced Mexica tributary dominance (structure: they paid tribute, provided military service, had limited autonomy), they faced a Spanish offer of alliance and greater autonomy (structure: Spanish promised Tlaxcaltec would not be tributaries but allies), they faced the real possibility that Mexica could crush Spanish if Tlaxcaltec did not support them (structure: without Tlaxcaltec, Spanish defeat became likely). Within those constraints, they chose alliance with Spanish. That choice was rational given their reference point (Mexica dominance) and the alternative being offered (Spanish partnership with greater autonomy). Their choice determined the outcome.
The insight: structure determines which choices are possible. Agency determines which possible choice gets selected. Spanish military superiority made indigenous coalition failure more likely; it did not make it inevitable. Marina's translation made diplomatic negotiation possible; it did not make it mandatory. Moctezuma's pragmatism made negotiating strategy rational; it did not predetermine its success. Each actor operated within structural constraints, made consequential choices within those constraints, and those choices reverberated across the system.
The pure-structure argument says: Spanish had superior military technology. Indigenous people faced a militarily superior force. Therefore Spanish victory was inevitable. This argument explains why Spanish victory was likely; it does not explain why Spanish victory happened when it did, through what processes, with which specific sequence of alliances. Inevitable-victory arguments cannot explain contingency.
The pure-agency argument says: Marina translated, Moctezuma negotiated, Tlaxcaltec chose alliance, therefore Spanish victory was contingent on those choices. This argument explains which choices mattered; it does not explain why those choices operated within the constraints they did, why Spanish military technology created an asymmetry that made some choices more costly than others. Agency-centered arguments cannot explain why certain outcomes became more likely than others.
The full historical explanation requires both. Spanish military advantage created a probability landscape in which certain outcomes became more likely. Within that landscape, individual actors made choices. The interaction between probability landscape and individual choice created the actual history that happened.
This is where Townsend's work is precisely right: conquest was not inevitable, but it was not equally probable across all possible paths either. Spanish military superiority made indigenous coalition failure more probable. Moctezuma's decision to negotiate rather than mobilize total resistance made Spanish ability to exploit coalition fractures more probable. Marina's translation made indigenous acceptance of Spanish hierarchy more probable. Tlaxcaltec choice to ally with Spanish made Spanish military superiority actually decisive. Each choice was made within structural constraints, and each choice shifted probabilities.
The outcome was contingent — it could have gone differently if different choices had been made. The outcome was also not equally likely — structural factors made some choices more probable and more likely to produce particular outcomes. Agency and structure together shaped history. Neither alone explains it.
Psychology — Constraint as Liberating Framework: Defensive Pragmatism: How Constraints Enable Clear Decision-Making Under Uncertainty
Psychology reveals something counterintuitive: absolute freedom paralyzes decision-making, while clear constraints enable decisive action. Moctezuma facing infinite possible responses to Spanish arrival (total mobilization? negotiation? appeasement? aggressive attack? careful probing?) faced decision paralysis. The institutional structures he inherited — calpolli organization, tributary relationships, established protocols for responding to foreign powers — provided framework that made decision-making possible. Within those constraints, he could make pragmatic choices.
Marina facing the possibility of translation work could theoretically translate in infinite ways (inflammatory, diplomatic, fragmentary, elaborate). The constraint that she was enslaved and her life depended on usefulness actually made her decision clearer: she needed to translate in ways that were useful to her Spanish masters. Within that constraint, she chose diplomatic translation that served her strategic understanding of what was actually happening.
The psychological insight: constraints enable agency by reducing the decision space to manageable size. Infinite freedom is paralyzing. Clear constraints create framework within which meaningful choice becomes possible. This is counterintuitive because psychology and popular culture celebrate "freedom" and "unlimited possibility." But decision-making research consistently shows: people make better decisions, more decisive choices, within clear constraints than in situations of infinite possibility. Marina's constraint (she must be useful to survive) actually enabled her to make strategic choices. Moctezuma's constraints (institutional structures he inherited) enabled him to navigate unprecedented situation with pragmatic decision-making.
The handshake: Psychology explains why structure enables agency rather than erasing it. Constraints create the framework within which meaningful choice becomes possible. The most constrained actors are often the ones forced to make the most consequential choices because they cannot afford indecision. This inverts the common narrative that constraint = lack of agency. In reality, constraint = clarified decision space = possible agency.
Behavioral Economics — Reference Points and Option Architecture: Reference Dependence: How Structural Context Determines Which Options Seem Rational
Behavioral economics reveals that choices are never made against an objective standard. They are made relative to a reference point. Moctezuma's reference point was "Mexica position as dominant regional power with established tributary relationships." Against that reference point, Spanish arrival was dramatic disruption. Should he negotiate or fight? The question is not answerable without the reference point. Against the reference point of Mexica dominance, negotiation looked like loss (giving up autonomy). But negotiation only looked like loss relative to that reference point. Against a different reference point (Mexica could be destroyed if Spanish form external alliance), negotiation looked like preservation.
Tlaxcaltec reference point was "subordinate tributary to Mexica dominant power." Against that reference point, Spanish offer of alliance was enormously attractive (escape from subordination, gain autonomy, gain military advantage). The choice to ally with Spanish was rational given their reference point. It would have been irrational against a different reference point (if they were already equal to Mexica).
Marina's reference point was "enslaved person with no formal rights." Against that reference point, she could survive by being useful. She could gain marginal status improvements (from some Spanish masters, she gained personal favor, protection, better material conditions) by translating in ways that served Spanish interests. Her choice to translate diplomatically was rational given her reference point.
The handshake: Behavioral economics explains why the same structural situation produces different choices from different actors with different reference points. Moctezuma negotiates because his reference point makes him experience negotiation as loss (from position of dominance). Tlaxcaltec choose alliance because their reference point makes them experience alliance as gain (from position of subordination). Marina translates diplomatically because her reference point makes her experience useful service as survival strategy. The structure (Spanish military advantage) is the same; the choices differ based on reference points. This means: understanding choice requires understanding reference points — the prior institutional and personal history that makes different outcomes seem rational to different actors. Agency is not choosing freely; it is choosing rationally relative to one's reference point within structural constraints.
The sharpest implication: If conquest was contingent on specific choices (Marina's translation, Moctezuma's negotiation, Tlaxcaltec alliance), then Mexica could have stopped Spanish conquest through different choices. They could have refused to negotiate, forced Spanish into pitched battles at disadvantage, maintained coalition, prevented Tlaxcaltec alliance. Cortés could not have conquered by military force alone; conquest required indigenous choices that allowed him to exploit indigenous political divisions. This means: indigenous defeat was not inevitable. It was chosen, in the sense that choices made by indigenous actors at specific moments allowed Spanish victory to become possible. This is historically uncomfortable because it means: indigenous people cannot claim they were simply overpowered by superior military force. Some indigenous leaders chose subordination because subordination seemed more rational than the alternatives they perceived. Moctezuma chose negotiation over total mobilization. Tlaxcaltec chose alliance over coalition. Those were intelligible choices given their reference points. But they were choices. This means indigenous people bear some responsibility for conquest's shape, even though Spanish initiated invasion and Spanish benefited most. This is hard to say and harder to hear. But it is what the evidence shows.
