Costa Rica: 20th Century Developments

by Strong Americas | Aug 16, 2026

Costa Rica's twentieth century was defined by an unusually stable democratic tradition, one that set the country apart from many of its Central American neighbors. Free and competitive elections, first held in 1899, established a pattern of civilian government that persisted through most of the century, aided by a political culture that increasingly rejected military rule.

That trajectory was interrupted twice. Between 1917 and 1919, Federico Tinoco governed as a dictator after seizing power in a coup, though his rule proved short-lived. A far more consequential rupture came in 1948, when Jose Figueres Ferrer led an armed uprising following a disputed presidential election. The resulting 44-day civil war, which claimed more than 2,000 lives, remains the deadliest event in the country's twentieth-century history. The junta that emerged victorious drafted a new constitution guaranteeing universal suffrage and, notably, abolishing the national army.

In the decades that followed, Costa Rica built an extensive social welfare system, expanding public education, establishing national health care, and investing in social security programs aimed at reducing inequality. These reforms, combined with peaceful transfers of power and growing political participation, helped the country consolidate its democratic institutions by century's end, cementing its reputation as one of the region's most stable republics.
