History of Portugal: Chronological Hub

Portugal's history spans from its 12th-century consolidation as a nation-state to its era as a global maritime power and its 20th-century transition from dictatorship to European democracy.

Major Historical Eras

The Medieval Kingdom (1139–1415)

Portugal was established as an independent kingdom in **1139** by Afonso Henriques following the Battle of Ourique. The Reconquista concluded in **1249** with the conquest of the Algarve, establishing Portugal's modern continental borders.

The Age of Discovery and Empire (1415–1822)

Beginning with the **1415** conquest of Ceuta, Portugal pioneered maritime exploration. Key milestones include the **1494** Treaty of Tordesillas and Vasco da Gama reaching India in **1498**. The empire's focus shifted to Brazil after the 17th-century loss of Asian spice monopolies.

Crisis and the Fall of the Monarchy (1755–1910)

The **1755** Lisbon earthquake crippled the capital. The 19th century was marked by the **1807** Napoleonic invasion, the **1822** independence of Brazil, and the **1890** British Ultimatum, which severely damaged monarchical legitimacy.

Authoritarianism and Revolution (1933–1974)

The **Estado Novo** (1933–1974) under António de Oliveira Salazar enforced isolationism and corporatism. Decades of colonial wars (1961–1974) led to the **Carnation Revolution** on April 25, 1974, a nearly bloodless military coup that restored democracy.

Modern Democratic Portugal (1976–Present)

Portugal joined the **European Economic Community (EEC)** in 1986. Following the **2011** debt crisis and international bailout, the country has transitioned into a tourism and technology-driven economy.
