How a 1926 Coup Triggered a Civil War and Decades of American Military Involvement
When a conservative strongman seized power in Nicaragua, he sparked a brutal civil war that drew in the United States. As Liberal rebels marched on the capital, American intervention became inevitable, ultimately leading to a fragile peace and the rise of a legendary guerrilla resistance that lasted until 1933.
The conflict began in January 1925 when Emiliano Chamorro, a Conservative, launched a coup by seizing the Loma Fortress in Managua. By removing the democratically elected government and purging Liberals from Congress, he triggered a rebellion that erupted into full-scale civil war by May 1926. As the fighting intensified, the United States grew increasingly alarmed by reports that Mexico was supplying the Liberal rebels with arms, fearing the rise of a left-wing, Bolshevist-aligned regime in the region.
The war saw intense combat, most notably the Battle of Chinandega in February 1927, where fire destroyed much of the city. As Liberal forces advanced on Managua, the United States intervened diplomatically to prevent a wider conflict. Henry L. Stimson, sent by President Calvin Coolidge, negotiated the Peace of Tipitapa with Liberal commander José María Moncada in May 1927. The agreement mandated disarmament, the retention of Adolfo Díaz as president, and the creation of a new National Guard, with soldiers receiving ten U.S. dollars for every rifle or machine gun surrendered.
While the treaty ended the civil war, it did not bring total peace. General Augusto César Sandino, a Liberal commander who had achieved notable victories at Mount Yucapuca and Jinotega, denounced the settlement as treasonous. Refusing to lay down his arms, Sandino launched a guerrilla campaign against the Nicaraguan government and the U.S. Marine Corps. His rebellion, which began with a battle at Ocotal in July 1927, persisted for years, marking the start of a long-term struggle that would define Nicaraguan politics until 1933.
