Portugal

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.

During the Age of Discovery, particularly in the 15th and 16th centuries, Portugal established one of the longest-lived maritime and commercial empires, becoming one of the main economic and political powers of the time. By the early 19th century, events such as the 1755 Lisbon earthquake, the country's occupation during the Napoleonic Wars, and the resulting independence of Brazil in 1822 led to a marked decay of Portugal's prior opulence. This was followed by the civil war between liberal constitutionalists and conservative absolutists over royal succession from 1828 to 1834. The 1910 revolution deposed Portugal's monarchy and established the democratic but unstable Portuguese First Republic, later superseded by the authoritarian regimes of Ditadura Nacional (National Dictatorship) and Estado Novo (New State). Democracy was restored after the Carnation Revolution (1974), ending the Portuguese Colonial War and eventually losing its remaining colonial possessions.

Portugal has had a profound cultural, architectural, and linguistic influence, with a legacy of around 300 million Portuguese speakers around the world. Today, it is a developed country with an advanced economy relying chiefly upon services, industry, and tourism. Portugal, a member of the United Nations, the European Union, the Schengen Area, and the Council of Europe, was one of the founding members of NATO, the eurozone, the OECD, and the Community of Portuguese Language Countries.
