Nicaragua’s political landscape in the early 20th century was marked by turmoil and significant foreign intervention. The U.S. involvement in Nicaragua, particularly between 1912 and 1933, highlights the complex interplay of domestic instability and international interests that shaped the nation’s history. This period saw multiple interventions by the United States, aimed at promoting stability in Central America but often leading to prolonged conflict and resentment.
The 1912 Intervention and Prolonged U.S. Presence
In 1912, Nicaragua was embroiled in a revolution that threatened the nation’s stability. The United States, concerned about its strategic and economic interests in the region, intervened to quell the uprising. U.S. Marines were deployed to Managua, and their presence was maintained until 1925. During this time, the U.S. sought to stabilize the country and secure its interests, which included protecting American businesses and maintaining influence over the region’s political dynamics.

The 1923 Treaties and Efforts for Regional Stability
In an effort to promote broader stability in Central America, five nations, including Nicaragua, signed treaties in Washington D.C. in 1923. These agreements were designed to limit the arms race in the region, establish arbitration mechanisms for resolving disputes, and foster a sense of peace among the Central American countries. Despite these efforts, Nicaragua’s internal political struggles continued to challenge these goals.
The 1924 Election and U.S. Withdrawal Plans
The 1924 Nicaraguan election resulted in the formation of a coalition government, with Carlos Solorzano as president and Juan B. Sacasa as vice-president. This political transition was seen as a step toward stability, and the United States planned to withdraw its Marines following the election. However, delays and ongoing instability postponed the withdrawal until August 1925.
Continued Turmoil and the 1926 Chamorro Coup
Political instability persisted, and in 1926, Emiliano Chamorro seized power in a coup, violating the earlier treaties aimed at maintaining peace. His actions triggered a revolution on the east coast near Bluefields, leading to further U.S. intervention. At the request of the Nicaraguan government, the U.S. sent warships to protect American lives and property. Admiral Latimer declared Bluefields a neutral zone, a move that was accepted by both the government and the rebels.
Failed Peace Talks and the Rise of Adolfo Díaz
In October 1926, the United States facilitated peace talks by providing a neutral meeting place, although it did not directly participate. Unfortunately, these negotiations failed when Sacasa’s delegation abruptly withdrew. Subsequently, adhering to constitutional procedures, the Nicaraguan Congress appointed Adolfo Díaz as president, and the United States officially recognized his government on November 17, 1926.
U.S. Support and Arms Embargo
As the conflict continued, President Díaz requested further U.S. support, accusing Mexico of aiding the rebels. In response, the United States imposed an arms embargo on Nicaragua and urged other Central American nations to do the same. However, Mexico did not participate in the embargo, and evidence indicated that significant quantities of arms continued to reach the Nicaraguan rebels even after August 1926.
The Legacy of U.S. Intervention in Nicaragua
This period in Nicaraguan history underscores the complexities of international intervention and the lasting impact of foreign involvement in domestic affairs. The U.S. intervention, while aimed at stabilizing the country, often exacerbated internal conflicts and left a legacy of mistrust and resentment. The events of the 1910s and 1920s illustrate how Nicaragua’s internal struggles were intertwined with the geopolitical interests of its neighbors and the United States.
