The Country Without an Army Since 1948 (And Why Nobody Invades It): The Story of Costa Rica

In a world where military spending continues to rise and global conflicts dominate international headlines, the idea of a country voluntarily abolishing its army seems almost impossible. Yet for more than 75 years, Costa Rica has challenged the assumption that military power is essential for survival. Since 1948, the nation has had no standing military, making it one of the few countries in the world to rely on diplomacy, international law, and democratic institutions rather than armed force for its national security.

Costa Rica’s decision to abolish its military came after a disputed presidential election sparked a brief but bloody civil war in 1948 that lasted 44 days and claimed around 2,000 lives.

Before 1948, Costa Rica had two main political sides that disagreed about who should lead the country. One group supported Rafael Ángel Calderón Guardia (National Republican Party), a former president who wanted his political ally and the current president, Teodoro Picado (National Republican Party), to stay in power. The other group supported Otilio Ulate Blanco (National Union Party), who believed the government had become unfair and undemocratic, alongside the majority of the public.

When opposition candidate Otilio Ulate Blanco (NUP) appeared to win the election, the government claimed there had been cheating and cancelled the results, even though there was little evidence. In support of Ulate, José Figueres Ferrer led a rebellion against the government, and the civil war began. After Figueres’ victory, he argued that armies gave governments excessive power to suppress democracy rather than respect it, which led to the abolition of Costa Rica’s military. The money was redistributed to schools, healthcare, and public welfare instead, and the decision was written into Article 12 of the 1949 Constitution.

Why Did Costa Rica Abolish Its Military?

Costa Rica is not completely defenseless and relies on several alternative methods of protecting its sovereignty. The country maintains police forces, border guards, and specialised security agencies responsible for law enforcement, organised crime, counter-narcotics operations, and border security. While these forces possess limited military-style capabilities, they are fundamentally civilian institutions rather than armed forces.

More importantly, Costa Rica places significant emphasis on diplomacy and international cooperation. It is an active member of the United Nations, the Organization of American States (OAS), and the Inter-American Court of Human Rights, which is headquartered in San José. These organisations provide diplomatic channels for resolving disputes peacefully rather than through military confrontation. Costa Rica’s close relationship with the U.S. has also acted as an informal security guarantee, as cooperation on intelligence, anti-drug operations, and regional security has strengthened the country’s strategic position.

How Does Costa Rica Maintain Security Without an Army?

At first glance, Costa Rica appears extremely vulnerable. However, two key geopolitical realities help explain why invasion has never become a serious threat.

Geographically, Costa Rica has no significant natural resources that would make conquest economically worthwhile. Its neighbours, Nicaragua and Panama, have generally prioritised regional stability over territorial expansion, while Central America has experienced increasing diplomatic cooperation since the late twentieth century.

Instead of projecting military power, Costa Rica has huge influence through diplomacy, democratic governance, environmental leadership, and international cooperation. As a respected democracy with a long-standing reputation for peace, any military invasion of Costa Rica would likely provoke significant diplomatic consequences, making aggression politically costly for any potential attacker.

Why Has Nobody Invaded Costa Rica?

Costa Rica's decision to abolish its military has helped establish it as one of Latin America's most stable democracies, a high-income economy with high literacy rates, a long life expectancy, and global recognition for its environmental leadership. By redirecting defence spending towards social welfare, the country has invested heavily in human development rather than military power.

However, Costa Rica faces security threats such as organised crime, drug trafficking, and cybercrime. Without armed forces, the country depends heavily on police capabilities and international partnerships to address these challenges. Costa Rica's success is ultimately down to its unique geopolitical circumstances and cannot be replicated worldwide. Unlike countries such as Ukraine or South Korea, Costa Rica faces no immediate military threat from hostile neighbours.

Successes and Limitations of Having No Military

While only a few countries could realistically abolish their militaries, Costa Rica demonstrates that national security cannot be measured solely by the size of a defence budget or the strength of an armed force. Democratic institutions, public trust, and international legitimacy can be equally important foundations of long-term stability. More than seventy-five years after abolishing its army, Costa Rica remains one of Latin America's most stable democracies, proving that, in the right circumstances, investing in people rather than weapons can become one of the most powerful forms of national security.
