Aragon (ˈærəɡən , USalso-ɡɒn,_-goʊn ; Spanish and Aragón aɾaˈɣon; Aragó əɾəˈɣo) is an autonomous community in Spain, coextensive with the medieval Kingdom of Aragon. In northeastern Spain, the Aragonese autonomous community comprises three provinces (from north to south): Huesca, Zaragoza, and Teruel. Its capital is Zaragoza. The current Statute of Autonomy declares Aragon a historic nationality of Spain.
Covering an area of , the region's terrain ranges diversely from permanent glaciers to verdant valleys, rich pasture lands and orchards, through to the arid steppes of the central lowlands. Aragon is home to many rivers—most notably, the river Ebro, Spain's largest river in volume, which runs west–east across the entire region through the province of Zaragoza. It is also home to the highest mountains of the Pyrenees.
the population of Aragon was 1,326,261, with slightly over half living in the capital city, Zaragoza. In 2020, the economy of Aragon generated a GDP of €34687 million, which represents 3.1% of Spain's national GDP, and is currently 6th in per capita production behind Madrid, Basque Country, Navarre, Catalonia and La Rioja.
In addition to its three provinces, Aragon is subdivided into 33 comarcas or counties. All comarcas of Aragon have a rich geopolitical and cultural history from its pre-Roman, Celtic and Roman days, four centuries of Islamic rule as Marca Superior of Al-Andalus or kingdom (or taifa) of Saraqusta, as lands that once belonged to the Frankish Marca Hispanica, counties that later formed the Kingdom of Aragon, and eventually the Crown of Aragon.
The area of Aragon is 47720km2 of which 15636km2 belong to the province of Huesca, 17275km2 to the province of Zaragoza and 14810km2 to the province of Teruel. The total represents a 9.43% of the surface of Spain, being thus the fourth autonomous community in size behind Castile and León, Andalusia, and Castile-La Mancha.
It is located in the northeast of the Iberian Peninsula, at a latitude between 39o and 43o'N in the temperate zone.
