The 5 October 1910 revolution was the overthrow of the centuries-old Portuguese monarchy and its replacement by the First Portuguese Republic. It was the result of a coup d'état organized by the Portuguese Republican Party.

The swift compliance by the government to the British demands was seen as a national humiliation by a broad cross-section of the population and the elite. This ramified deep dissatisfaction with the new king, Carlos I of Portugal, the royal family and the institution of the monarchy, all of which were seen as responsible for the alleged process of "national decline". The situation was aggravated by the severe financial crisis that occurred between 1890 and 1891, when
