Republic Day

Portugal · Date: Monday, October 5, 2026

Republic Day (Implantação da República) on October 5th commemorates the 1910 revolution that overthrew the Portuguese monarchy, establishing the First Portuguese Republic. It marks a key turning point in the nation's political history.

Origin & history

The holiday originates from the political upheaval of the early 20th century. The Portuguese monarchy had become increasingly unpopular due to financial crises, colonial disputes, and the British Ultimatum of 1890, which humiliated the nation. The Republican Party, gaining support among the military and urban middle classes, organized a coup. On October 3–4, 1910, republican forces, including soldiers and civilian militias, rose up in Lisbon. After two days of street fighting that resulted in about 40 deaths, the revolutionaries took control. King Manuel II fled into exile, and a provisional government proclaimed the Republic on October 5, 1910.

The new regime introduced secularism, civil liberties, and many modern reforms, though it would later face instability. The date was officially declared a holiday in 1911. It was suppressed during the Estado Novo dictatorship (1933–1974) but restored after the Carnation Revolution. Today it is one of Portugal's national holidays, though its observance has fluctuated over time.

In 2012, the government briefly removed it as a paid holiday for economic reasons, but public pressure and political opposition led to its restoration in 2016. The holiday remains a symbol of Portugal's republican ideals and democratic values.

Customs & traditions

Republic Day is a public holiday, so government offices, banks, and many businesses close. Celebrations are more subdued than the Carnation Revolution (April 25) but include official ceremonies. The main event is a flag-raising ceremony at the Lisbon City Hall (Paços do Concelho) with the President and other dignitaries. Military parades and wreath-laying at monuments to the republic, such as the Tomb of the Unknown Soldier, are common.

In schools, children often learn about the history of the republic. Some cultural institutions offer free admission, and there are lectures and exhibitions about the First Republic. In recent years, there have been citizen rallies and concerts in public squares, especially in Lisbon.

Traditional food is not specifically associated with the holiday, but families may gather for a meal featuring typical Portuguese dishes like bacalhau (salt cod) or grilled sardines. Many people simply enjoy a day off, spending time with family or engaging in leisure activities.

Why it is celebrated

Republic Day celebrates the establishment of a republican form of government in Portugal, replacing monarchy with a system based on popular sovereignty and secularism. It honors the democratic principles of liberty, equality, and fraternity that the Republic sought to uphold. The holiday serves as a reminder of Portugal's long struggle for political reform and its commitment to democratic governance, even after periods of dictatorship. It is a day to reflect on the nation's history and the enduring importance of civic participation and civil rights.
