SUMMARY
Nicaragua became officially independent in 1840, after first declaring sovereignty from Spain in 1821, then from Mexico in 1823, and finally from the United Provinces of Central America. The country endured a major armed conflict beginning with the Sandinista revolution that overthrew the Somoza dictatorship, followed by a civil war between the Sandinista government and the Contra insurgency. The conflict came to an end in 1990. Since then, Nicaragua has not experienced a formal civil war or gang-related violence on the scale seen in some neighboring countries.
Since 1989, Nicaragua has experienced the intrastate, non-state, and one-sided categories of organized violence, as categorized by the UCDP.
Organized Violence in Nicaragua
Most of Nicaragua’s organized violence occurred prior to 1989, particularly during the civil war that defined the country’s political landscape in the 1980s. This period of intense intra-state violence came to an end with a negotiated peace settlement and national elections in 1990.
From 1990 until the early 2000s, Nicaragua experienced occasional localized violence, including land disputes and isolated confrontations between former combatants. However, this did not rise to the level of organized armed conflict under UCDP standards.
Unlike its neighbors Guatemala, El Salvador and Honduras, Nicaragua has not experienced widespread gang violence linked to MS-13 or M18. While youth gangs do exist, their activity has remained relatively low-profile and geographically limited.
Pre-1989 Conflicts
Nicaragua’s violent political history stretches back to the early 20th century, marked by U.S. military occupation (1912–1933) and the guerrilla resistance led by Augusto César Sandino. Following Sandino’s assassination, Anastasio Somoza García took power and established a dictatorship that ruled for over four decades (1937-1979). The Somoza regime, heavily backed by the United States, was known for corruption, repression, and its use of the National Guard to eliminate opposition. In response to the repressive Somoza regime, a leftist guerrilla movement emerged in the early 1960s that eventually evolved into three major groups, but reunited into the revolutionary coalition FSLN (Frente Sandanista de Liberación Nacional, Sandinista National Liberation Front) in the latter years of the struggle. The Sandinistas, as the FSLN members were called, overthrew the Somoza dictatorship in 1979 after an intra-state conflict which lasted for a year.
After two years of Sandinista rule, several counter-revolutionary forces collectively called the Contras (from the Spanish term contrarrevolucionario) surfaced and began to violently challenge the new socialist regime. The Sandinista-Contra conflict became one of the most iconic Cold War proxy wars in Latin America as the Contras were financed and trained by the U.S. through covert operations. The Contras consisted of various groups, but mainly of FDN (Fuerza Democrática Nicaragüense, Nicaraguan Democratic Forces). One common denominator for the Contras were their benefactors, namely the U.S. and Honduras. With their support, the Contras in an intra-state conflict against the government for eight years (1981-1989), during which rural populations, especially Indigenous and Afro-descendant communities along the Caribbean coast, were often caught in the crossfire. Civilian massacres, forced displacement, and use of child soldiers were documented on both sides. It was primarily the end of the U.S.-military support in the late 1980s which led the Contras to sign a series of peace agreements in 1987-1989. By the end of 1990, virtually all of the Contras had demobilized.
Nicaragua has also seen inter-state conflict, with the territorial conflict against Honduras in 1957. Both countries disputed the Mosquito Coast area, which had been contested since a 1906 arbitral award gave the territory to Honduras. The violent conflict was triggered in 1957 when Nicaragua claimed that some of its territory had been included in Honduras’ creation of a new administrative unit, Gracias a Dios, in the border region. The inter-state conflict ended when the OAS (Organization of American States) pushed for a withdrawal of Nicaraguan troops from the disputed area in order to await a judgement on the border from the UN International Court of Justice (ICJ). In 1960, the ICJ upheld the original arbitral award. Nonetheless, the case has continued to be litigated into the 21st century.
Nicaragua lending secondary warring support
In 2004, Nicaragua provided secondary warring support to the government of Iraq during the conflict that began that same year. Although the Nicaraguan government did not deploy troops, it supported the U.S.-led coalition by offering logistical and political backing, aligning itself with international efforts to stabilize Iraq following the fall of Saddam Hussein’s regime. Nicaragua’s contribution, while limited in military terms, signaled its alignment with U.S. foreign policy during that period and positioned the country as a participant in broader post–Cold War international security efforts. However, the UCDP does not classify Nicaragua as a secondary warring party in the conflict, but a government that provided support.
