Spain, officially the Kingdom of Spain (Spanish: Reino de España), is a sovereign state and a member state of the European Union. It is located on the Iberian Peninsula in southwestern Europe. Its mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and north east by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean. It is one of three countries—France and Morocco are the other two—to have both Atlantic and Mediterranean coastlines. Spain's 1,214 km (754 mi) border with Portugal is the longest uninterrupted border within the European Union.
Spanish territory also includes the Balearic Islands in the Mediterranean, the Canary Islands in the Atlantic Ocean off the African coast, three exclaves in North Africa, Ceuta, Melilla, and Peñón de Vélez de la Gomera that border Morocco, and the islands and peñones (rocks) of Alborán, Chafarinas, Alhucemas, and Perejil. With an area of 505,992 km2 (195,365 sq mi), Spain is the second largest country in Western Europe and the European Union, and the fifth largest country in Europe.
Modern humans first arrived in the Iberian Peninsula around 35,000 years ago. It came under Roman rule around 200 BCE, after which the region was named Hispania. In the Middle Ages it was conquered by Germanic tribes and later by the Moors to the south. Spain emerged as a unified country in the 15th century, following the marriage of the Catholic Monarchs and the completion of the centuries-long reconquest, or Reconquista, of the peninsula from the Moors in 1492. Spain expanded into a global empire in the early modern period which has left a legacy of over 500 million Spanish speakers today, making Spanish the world's second most spoken first language.
Spain is a democracy organised in the form of a parliamentary government under a constitutional monarchy. It is a developed country with the 13th largest economy in the world. It is a member of the United Nations, NATO, OECD, and WTO.
