Spain, officially the Kingdom of Spain, is a country in Southern and Western Europe with territories in North Africa. It spans most of the Iberian Peninsula and also includes the Canary Islands in the Atlantic, the Balearic Islands in the Mediterranean, and the autonomous cities of Ceuta and Melilla in mainland Africa. Its capital and largest city is Madrid.
The name Spain, or España, comes from Hispania, the name the Ancient Romans used for the Iberian Peninsula. The Phoenicians referred to the region as i-shphan-im, possibly meaning land of rabbits or hyraxes, land of metals, or northern island. Roman coins from the reign of Hadrian show a female figure with a rabbit at her feet, and Strabo called it the land of the rabbits.
Spain's unification is often traced to the marriage of Isabella I of Castile and Ferdinand II of Aragon, whose crowns were united in 1469. The dynastic union of Castile and Aragon in 1479 under the Catholic Monarchs is often seen as the de facto unification of Spain as a nation state, though each kingdom remained separate in law, currency, and language.
The Spanish Civil War broke out in July 1936 when part of the military launched a coup, dividing the country between the Republican government and the Nationalist rebels. The war claimed over 500,000 lives, and General Francisco Franco's side won on the 1st of April 1939, imposing a dictatorship that lasted until his death in November 1975.
Spain is a secular parliamentary democracy and a constitutional monarchy, with King Felipe VI as head of state since the 19th of June 2014. Under the Constitution of 1978, approved by 88% of voters, the country is organised into 17 autonomous communities and two autonomous cities, making it one of the most decentralised states in Europe.
Catalonia identifies itself as a nationality and gained early self-government under the 1978 constitution. In October 2017 the Parliament of Catalonia voted to unilaterally declare independence, but no country recognised it as a separate state. A 2024 University of Barcelona poll found over 50% of Catalans would vote against independence and fewer than 40% in favour.
