Mexican Revolution Study Guide

📖 Core Concepts Mexican Revolution (1910‑1920) – A decade‑long, regionally varied armed conflict that toppled the Porfirian regime, destroyed the Federal Army, and produced the 1917 Constitution. Constitutionalist faction – Led by Venustiano Carranza; ultimately prevailed, drafted the 1917 Constitution, and established a revolutionary army loyal to the civilian government. Key “Plan” documents – Plan de San Luis Potosí (1910, Madero), Plan of Ayala (1911, Zapata), Plan of Guadalupe (1913, Carranza), Plan of Agua Prieta (1920, Obregón/Calles). Ejido – Communal land tenure created by the 1917 Constitution (Art. 27) to return land to peasants; later institutionalized under the post‑revolutionary regime. PRI lineage – National Revolutionary Party (1929) → Party of the Mexican Revolution (1938) → Institutional Revolutionary Party (1946), the political vessel for revolutionary legitimacy. 📌 Must Remember Dates: Revolution = 20 Nov 1910 – 1 Dec 1920; Constitution = 1917. Death toll: 1 million civilians killed; total deaths 1.5 million. Major leaders & alignments: Madero – Liberal, anti‑reelectionist, president 1911‑13. Huerta – Coup leader, president 1913‑14. Carranza – Constitutionalist, president 1917‑20. Villa – Northern commander, defeated Huerta, later rebel. Zapata – Southern peasant leader, agrarian reform. Obregón – Sonoran general, president 1920‑24. Calles – President 1924‑28, founder of PNR. Key constitutional articles: Art. 27 (land & natural resources), Art. 123 (labor rights), Art. 3 (secular education). Ten Tragic Days (Feb 1913) – Armed clash that resulted in Madero’s overthrow and Huerta’s seizure of power. Zimmermann Telegram (1917) – German proposal to Mexico to reclaim lost U.S. territory; its exposure pushed the U.S. into WWI. 🔄 Key Processes Revolutionary mobilization (1910‑1911) Madero’s Plan de San Luis Potosí → calls for “effective voting, no re‑election.” Spontaneous uprisings in Morelos, Chihuahua, Sonora → leaders Orozco, Villa, Zapata, Carranza join. Coup & Counter‑revolution (1913‑1914) Huerta allies with Félix Díaz → Pact of the Embassy → Madero’s resignation/assassination. Constitutionalist Army (Carranza) forms → defeats Huerta by July 1914. Factional wars (1914‑1915) Convention of Aguascalientes attempts reconciliation → split Carranza vs. Villa/Zapata. Battle of Celaya (1915) – Carranza’s forces defeat Villa. Constitution drafting (1916‑1917) Carranza calls constituent congress → excludes Huerta‑supporters, Villa, Zapata. Adopt Articles 27, 123, 3 → ratified 1917. Power consolidation (1917‑1920) Carranza governs under new constitution, suppresses opposition (assassinates Zapata 1919). Plan of Agua Prieta (1920) – Obregón, Calles, de la Huerta rebel, force Carranza’s flight. Institutionalization (1920‑1940) Successive Sonoran presidents (Obregón, Calles, Cárdenas) professionalize army, create PRI, implement limited land reform & labor laws. 🔍 Key Comparisons Madero vs. Carranza – Madero: Democratic reforms, kept Federal Army → alienated revolutionaries. Carranza: Constitutionalist, drafted 1917 Constitution, used revolutionary army, suppressed radicals. Villa vs. Zapata – Villa: Northern cavalry, focused on military victory, later political rebel. Zapata: Southern peasant leader, single‑issue agrarian reform (Plan of Ayala). Huerta vs. Constitutionalist Army – Huerta: Relied on expanded conscripted Federal Army (50k → 250k). Constitutionalists: Mobilized volunteer regional forces, emphasized political legitimacy. 1917 Constitution vs. 1857 Constitution – 1917 adds strong state control of land (Art. 27), labor rights (Art. 123), secular education (Art. 3). ⚠️ Common Misunderstandings “The Revolution ended in 1917.” – The armed phase continued until 1920 (Carranza’s fall) and political consolidation lasted into the 1940s. “All revolutionaries wanted land reform.” – Only Zapata’s movement prioritized it; Carranza’s agenda was constitutional and political, not radical agrarian. “The Federal Army stayed intact throughout.” – It was dismantled after Huerta’s defeat; a new revolutionary army replaced it. “The PRI is a purely democratic party.” – It originated as a top‑down instrument to channel revolutionary legitimacy and control succession (no‑reelection rule). 🧠 Mental Models / Intuition “Plan → Army → Constitution” – Each major “Plan” (San Luis, Guadalupe, Agua Prieta) signals a shift: new leadership, mobilization of forces, and eventual institutionalization. “North vs. South vs. Center” – Northern leaders (Carranza, Obregón, Calles, Villa) fought over political control; Southern leader (Zapata) stayed focused on agrarian justice. “Foreign interest = leverage” – U.S. non‑recognition of Huerta, arms supply to Constitutionals, and the Zimmermann Telegram all show how external powers shaped internal outcomes. 🚩 Exceptions & Edge Cases Huerta’s land‑reform gestures – Restored ejido lands to Yaqui and Mayo peoples, but his reforms stalled and lost elite support. Zapata’s alliance with Villa (1914) – Brief, pragmatic coalition that dissolved quickly; Zapata never fully trusted Villa’s broader agenda. Constitutional article implementation – Carranza did not enforce the radical land‑reform clauses of Art. 27; true redistribution came later under Cárdenas. 📍 When to Use Which Analyzing cause of a leader’s downfall: Madero → look at reliance on Federal Army (Katz’s “basic cause”). Huerta → consider foreign non‑recognition + military defeats. Carranza → examine failure to secure succession and opposition from Sonoran generals. Identifying revolutionary faction: Plan of Guadalupe → Constitutionalist (Carranza). Plan of Ayala → Zapatista (agrarian). Plan of Agua Prieta → Sonoran revolt against Carranza. Evaluating labor rights: Use Article 123 (1917 Constitution) for legal framework; examine Carranza’s limited enforcement vs. Cárdenas’ expansion. 👀 Patterns to Recognize “Plan → battle → treaty” – Major turning points follow a declared plan, a decisive battle, then a political settlement (e.g., Plan of Guadalupe → defeat of Huerta → Treaty of Veracruz). “Foreign support ⇄ legitimacy” – U.S. recognition often precedes a faction’s consolidation (Constitutionalists 1915, Obregón 1923). “Assassination → power vacuum → new faction” – Madero’s 1913 death → Huerta; Zapata’s 1919 death → Carranza’s unchallenged rule. 🗂️ Exam Traps Confusing dates of leadership: Remember Díaz resigned May 1911, Madero served 1911‑13, Huerta 1913‑14, Carranza 1917‑20. Attributing the 1917 Constitution to Carranza’s policies: Carranza oversaw its drafting but did not fully implement radical land reforms; later leaders did. Assuming all revolutionary leaders were allied: Villa and Zapata briefly allied (1914) but soon split; Orozco opposed Madero despite earlier cooperation. Mixing up the Ten Tragic Days with the Convention of Aguascalientes: Ten Tragic Days = Feb 1913 coup; Aguascalientes = Oct 1914 factional conference. --- Study this guide by reviewing each section, then test yourself: can you name the key plan, leader, and outcome for each major phase?
