Cuba Explained: History, Government, and Life on the Island

1. Cuba at a Glance

Cuba is the largest island in the Caribbean, sitting about 90 miles south of Key West, Florida, across the Straits of Florida. Havana is the capital and largest city. Spanish is the official language. The country's population has been falling for several years — Cuba's National Office of Statistics and Information (ONEI) reported roughly 10.1 million residents in its 2023 count, down from about 11.2 million a decade earlier, a decline driven mainly by a historic wave of emigration alongside a falling birth rate.

2. Cuba's History in Brief

Spain colonized Cuba starting in 1511 and ruled it for nearly four centuries, building a plantation economy dependent on enslaved African labor to grow sugar and tobacco. Cuba won formal independence from Spain in 1898 after the Spanish-American War, though the Platt Amendment gave the United States the right to intervene in Cuban affairs until 1934, and Cuba did not become a fully sovereign republic until 1902. The following five decades were marked by recurring political instability, culminating in Fulgencio Batista's 1952 coup, which suspended the constitution and set the stage for the armed uprising that followed.

That uprising is the single most consequential event in modern Cuban history: the 1959 revolution, when Fidel Castro's rebel movement forced Batista to flee the island. For the full timeline — the Moncada Barracks attack, the Granma landing, the Sierra Maestra guerrilla campaign, and Batista's collapse — see our dedicated Cuban Revolution explainer. The revolution's aftermath included the nationalization of foreign-owned businesses, the U.S. trade embargo, and the October 1962 Cuban Missile Crisis, covered in our Missile Crisis explainer.

3. Cuba's Government Explained

Cuba is a one-party socialist state. The Communist Party of Cuba (PCC) has been the country's only legal political party since 1965, and Cuba's constitution names the PCC as the "leading force" of society and the state. Miguel Díaz-Canel became president in 2019 and was re-elected by the National Assembly in 2023, becoming the country's first head of state born after the 1959 revolution and the first non-Castro to lead Cuba since Fidel Castro took power. See our Díaz-Canel explainer for verified biographical facts, and our full list of Cuban presidents for the country's complete post-independence political history.

Manuel Marrero Cruz serves as prime minister, a post reinstated in 2019 after Cuba's constitution was rewritten that year to formally separate the head-of-state and head-of-government roles for the first time since the 1970s.

4. Cuba's Economy in Brief

Cuba runs a centrally planned economy alongside a growing, legally recognized private sector. Since 2021, the government has authorized micro, small, and medium private enterprises (MiPyMEs) for the first time since the revolution, and Cuba now also runs a dual-currency-style system in practice: the Cuban peso (CUP) for official transactions and a widespread informal dollar/euro exchange economy tracked by independent outlets like elTOQUE. Our Cuba economy explainer covers the MiPyME reform, state planning, and sector-by-sector detail, and our Cuban peso explainer covers the currency and exchange-rate side directly.

5. Cuba and the U.S. Embargo

The United States has maintained a trade embargo against Cuba since President John F. Kennedy's Proclamation 3447 took effect on February 7, 1962. The embargo — called the "bloqueo" in Cuba — bars nearly all trade and financial transactions between the two countries, with exceptions carved out over the decades for items like food, medicine, and licensed categories of travel. The UN General Assembly has voted nearly every year since 1992 to condemn the embargo, though the vote is non-binding and the embargo remains U.S. law. For the complete legal history, exceptions, and current general licenses, read our Cuba embargo explainer.

6. Culture: Language, Religion, and Literature

Cuban Spanish carries its own vocabulary shaped by the island's history — words like asere (friend), guagua (bus), and jaba (shopping bag) rarely appear outside Cuba and the Cuban diaspora. Cuba's national hero, José Martí, is also its most celebrated writer: a poet, journalist, and independence organizer whose 1891 collection Versos Sencillos later supplied the lyrics to "Guantanamera," Cuba's best-known song abroad. Later generations produced internationally recognized novelists, including Alejo Carpentier, a pioneer of magical-realist fiction, and Reinaldo Arenas, whose banned writing and eventual exile are documented in his memoir Before Night Falls.

Santería, an Afro-Cuban religion blending West African Yoruba orisha worship with Roman Catholic saint veneration, developed among enslaved Yoruba people brought to Cuba and remains widely practiced today, alongside Catholicism and a smaller Protestant population. Orishas such as Changó, Yemayá, and Ochún are venerated through rituals, music, and specific colors and symbols that show up widely in Cuban art and street life, particularly in Havana and Santiago de Cuba.

7. Cuba Today

Cuba today faces a severe energy crisis marked by rolling nationwide blackouts, driven by an aging, oil-fired power grid and fuel shortages — covered in depth in our Cuba energy crisis explainer. The government has responded partly by fast-tracking Chinese-financed solar plants. On the diplomatic front, recent U.S. actions — including sanctions tied to Executive Order 14404 targeting Cuban military-run conglomerate GAESA — are tracked on our Cuba sanctions tracker. For visitors, our Cuba travel hub and travel advisory tool cover current safety and entry requirements.
