In 1910, the Kingdom of Portugal was in crisis: people were angry over the 1890 British Ultimatum and the royal family. King Carlos I and his heir was assassinated in 1908, called the Lisbon Regicide. There was conflict between two political parties, Progressive and Regenerador. This caused political instability throughout Portugal. Republicans in Portugal thought Republicanism was a better way to manage the country, so, the Republican Party took advantage of the instability to overthrow the House of Braganza.
