Country in Southwestern Europe

Portugal, officially the Portuguese Republic, is a country in Southwestern Europe.

Portugal also includes the archipelagos of Madeira and the Azores in the Atlantic Ocean. The country has a population of 11.4 million, and Lisbon, its capital, is the largest city. Portugal's internal waters and territorial sea together account for two-fifths of its territory, and its exclusive economic zone is one of Europe's largest.

Portuguese Republic in Depth

History

The region has been inhabited by humans since approximately 400,000 years ago. Neanderthals roamed the southwestern Iberian Peninsula until 37,000 years ago, and anatomically modern humans arrived in what is now Portugal around 40,000 years ago. The onset of the Neolithic in the area dates to between 5500 BC and 5300 BC. In southern Portugal, Iron Age inscribed stele have been found, representing early evidence of writing in the Iberian Peninsula. Pre-Celtic tribes originally from the Ukrainian steppes inhabited mainland Portugal and the Lusitanians occupied mostly central, inland regions in 1250 BC. Celts may have spread westwards in Iberia in the latter 1st millennium BC. Phoenicians colonised Portugal during the 7th and 8th centuries BC.

Government and politics

Portugal has been a semi-presidential representative democratic republic since the ratification of the Constitution of 1976. The Constitution divides the core structures of the Portuguese political system among four sovereignty organs: the president, the government, the Assembly of the Republic, and the courts. There is universal suffrage for adults over 18 years of age, with a secret ballot for all elected offices. Portugal operates a competitive multi-party system at the national, regional, and local levels. There have been trends towards autocratisation.

The head of state of Portugal is the president who is elected to a five-year term by direct, universal adult suffrage.

Economy

Portugal is a high-income country with an advanced economy that follows the Mediterranean model. The country's economic policy is framed by strategic guidelines called Major Options, which are subsequently implemented through the State Budget. Portugal has the EU's 14th-largest economy by nominal GDP and the 12th-largest economy by PPP-adjusted GDP. Its PPP-adjusted GDP per capita stood at to 81% of the EU average in 2025. As of 2024, Portugal's service sector contributed the most for its economic output followed the industrial sector and its primary sector. In 2025, Portugal unemployment rate was 5.8%. As of 2024, its poverty rate after social transfers was 15.4% of the population while in 2023, the at-risk-of-poverty rate before social transfers stood at 40.3%.

Culture

Portugal's culture has developed due to the influence from various civilisations that have crossed Europe, especially the Mediterranean. Later, during the period of Portugal's engagement in the Age of Discovery, cultural elements from outside of Europe were introduced and became a central element of Portuguese national identity.

Portugal is known for its heritage and architecture, sacred sites, festivities, poetry, its music (especially the fado), and cuisine (including its wine). As of 2026, UNESCO inscribed 17 properties in Portugal on the World Heritage List.
