The February 1927 Revolt, sometimes also referred to as the February 1927 Revolution, was a military rebellion that took place between February 3 and 9, 1927, centered in Porto, the city where the insurgents' command center was installed and fought the main challenges. The revolt, led by Adalberto Gastão de Sousa Dias, ended with the surrender and arrest of the rebels and resulted in about 80 deaths and 360 injuries in Porto and more than 70 deaths and 400 injuries in Lisbon. It was the first consequent attempt to overthrow the Military Dictatorship that was then consolidated in Portugal following the 28 May 1926 coup d'état, which occurred nine months earlier, initiating a set of insurrectionary movements that became known as the "Reviralhism".
