Mexico starts far from any serious front, right next to 
the United States and with plenty of oil of its own. But internally it's still carrying the legacy of the Revolution: the 
Politicized Army spirit sums up almost three decades of revolutionary generals turned rulers, and regional caudillos who still haven't fully submitted to central power.
Historical Context
By the time the game starts in 1936, Mexico has gone through nearly two decades of unrest: the Mexican Revolution (1911-1920) completely redefined the country, and barely over that period the Cristero War (1926-1929) pitted the revolutionary state against Catholic peasant communities. Lázaro Cárdenas leads the country, mid-recovery but with the risk of political instability still very much present.
National Spirits at Start
Mexico starts with six national spirits that portray a country still digesting the legacy of its revolution: corruption, religious tension, foreign oil dependence, and an army more accustomed to politics than military professionalization.
Callistas
−20% political power gain, −10% construction speed — former president Calles's supporters enrich themselves and abuse their power, perpetuating a patronage system that corrupts every public office.
Weak Church
+10% factory output — the 1917 Constitution limits the influence of the Catholic Church, and the Mexican people finally seem ready for a secular state after the Cristero War.
Oil Concessions
No direct modifiers: foreign companies extract Mexican oil under concession contracts that pay far below its real value, leaving the country's reserves under indirect foreign control.
Politicized Army
+100% military leader cost, −20% planning speed — almost three decades of rulers drawn directly from the revolutionary army.
Caudillo Tensions Moderate
−5% stability — generals like Saturnino Cedillo in San Luis Potosí jealously guard their regional influence against central power.
Monroe Doctrine
No direct modifier: the United States protects the western hemisphere from outside powers, as long as Mexican politics stay aligned with its own.
The Legacy of the Caudillos
The Politicized Army and Caudillo Tensions Moderate spirits are two sides of the same coin: almost three decades of revolutionary generals turned presidents have left an army as accustomed to politics as to combat, and a network of regional strongmen who still haven't fully submitted to central power. Professionalizing the army or letting the caudillos keep carving out their own fiefdoms is one of the most important internal decisions of the playthrough.
The Focus Tree Branches
Mexico's tree is organized around several main blocks:
National Bank — the infrastructure branch: removes the threat of caudillo civil war and opens the door to a shift toward communism.
Plan of Agua Prieta — named after the real 1920 plan that brought the Sonoran generals to power: opens the door to a political realignment toward democracy, fascism, or communism.
Military Budget Review — military technology development.
Oil Field Expansion — manages foreign relations with the great powers and the possibility of joining their faction.
Control the Army — adjusts the political weight of the Church and the army itself within the state.
March Southwards — opens war goals against other American countries.
This guide doesn't go into the detail of the specific ideological routes that open up after Plan of Agua Prieta — the democratic route, the fascist route, the communist route — they're playthrough paths that will be covered in separate content later.
National Bank or Plan of Agua Prieta
The most important early decision pits National Bank — centralizes the economy and removes the caudillo civil war risk at its root, consolidating federal government power — against Plan of Agua Prieta, which opens the door to a deeper political realignment of the country.
For a first playthrough, National Bank is the safer route: it resolves the most urgent internal problem — the risk of caudillo fracture — before considering anything more ambitious. Plan of Agua Prieta gives more room to redefine the country's ideological direction, but requires actively managing that transition.
Far From the Bullets
Your geography isolates you from both the European and Pacific fronts, giving you enormous room to develop without the urgency the European powers suffer from. Your relationship with the United States, your giant neighbor, is the variable that really shapes your diplomatic and trade options.
- Industrial development and internal consolidation in the early years, with no pressure from any nearby front.
- Decide your relationship with Washington: close cooperation or greater outside independence.
- Your own oil resources as the basis for an industry less dependent on the outside world.
- If you want an active role in the war, build an expeditionary force with time to spare — the invasion isn't coming to you.
- For the land doctrine tree, with only 3 starting military factories,
Superior Firepower pays off more than chasing armor you won't be able to sustain.
The Giant Neighbor
The most common mistake is not taking advantage of the geographic calm and treating the playthrough with the same urgency as Europe, when Mexico has plenty of room to develop. The second is ignoring the relationship with the United States, which in practice shapes much of your room to maneuver. The self-sufficiency guide goes deeper into how to make the most of your oil.
Mexico in the Real War
If you're going to follow the historical script inside the Allies, what really matters isn't the exact dates but what you need to have ready at each stage. Here's what to do at each stage:
- Oil expropriation-style nationalization — nationalize and build up your oil industry early, while you have decades of peace ahead; don't wait for the pressure of war to force it through in a rush.
- Mexican tanker-style sinkings — if you want to avoid this casus belli, invest ahead of time in coastal defense and convoy escort; if instead you're looking for an excuse to align with the Allies, take it as your cue to do so formally.
- Declaration of war on the Axis — with no real invasion threat to your territory, this is a low-risk opportunity to align diplomatically with the Allies and collect postwar benefits without real combat exposure.
- Aztec Eagles-style squadron — if you want a token expeditionary contribution, prepare it in advance (aviation focuses, training) instead of scrambling one together late; a small, well-prepared force buys far more diplomatic goodwill than it costs.
Mexico's Achievements
Four achievements, with a strong revolutionary alternate-history flavor:

Sunset Invasion
Occupy a coastal province in Europe as Mexico while in a faction that contains only South American members or puppets.
The New Home of the Revolution
Put Trotsky in power and puppet the Soviet Union as Mexico.
The Revenge of Montezuma
As Mexico, restore the old borders with the USA.
