History
The island the Taíno called Borikén — the source of "Boricua", still used with pride — was colonised by Spain after Ponce de León's settlement in 1508. San Juan became one of Spain's most heavily fortified strongholds, its walls and the castles of El Morro and San Cristóbal built to hold the gateway to the Caribbean against the English, Dutch, and French; the historic core is now a UNESCO World Heritage Site. Sugar, coffee, and tobacco estates were worked by enslaved Africans until abolition in 1873, and Spain granted the island a brief autonomy in 1897.
In 1898 the United States took Puerto Rico from Spain in the Spanish-American War. Congress made Puerto Ricans US citizens in 1917, and in 1952 the island adopted its current status as a "Commonwealth" (Estado Libre Asociado), with its own constitution and elected governor but ultimate authority resting with Washington. Residents of the island vote in party primaries but not in the presidential election, and send only a non-voting delegate to Congress. Mid-century industrialisation under "Operation Bootstrap" pulled people from farms to factories and, in huge numbers, to the US mainland.
Since 2006 the economy has been in a long slump. A debt crisis of more than seventy billion dollars led Congress in 2016 to impose a federal oversight board and a restructuring process under the PROMESA law, deeply resented locally. In September 2017 Hurricane Maria devastated the island, causing an estimated several thousand excess deaths and destroying the electricity grid, with some areas left without power for months. Mass protests in 2019 ("el Verano del 19") forced out the governor over a leaked chat, and the grid — now run by a privatised operator — continues to fail, with island-wide blackouts as recently as 2024 and 2025. The status question — statehood, independence, or the current arrangement — remains unresolved despite repeated nonbinding plebiscites.
