Portugal, officially the Portuguese Republic, is a country located on the Iberian Peninsula in Southwestern Europe, whose territory also includes the Macaronesian archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe; its mainland west and south border with the North Atlantic Ocean; and in the north and east, the Portugal-Spain border, which constitutes the longest uninterrupted border line in the European Union. Portugal is the oldest nation-state in Europe. Founded in 1143, its current borders were established in mid-13th century, making them some of the most ancient in Europe and the world. Its archipelagos form two autonomous regions with their own regional governments. On the mainland, the Alentejo region occupies the biggest area but is one of the least densely populated regions of Europe. Lisbon is the capital and largest city by population, and it is also the main spot for tourists alongside Porto, the Algarve and Madeira.
As one of the oldest countries in Europe, its territory has been continuously settled and fought over since prehistoric times. The territory was inhabited by the Celtic and Iberian peoples. It was later ruled by the Romans, followed by the invasions of Germanic peoples together with the Alans and later the Moors, who were eventually expelled during the Reconquista. First founded as a county within the Kingdom of León in 868, Portugal formally became an independent kingdom with the Treaty of Zamora in 1143.
