The Portuguese Prime Minister and several officials are murdered in the Bloody Night coup.

Bloody Night is the name by which the radical revolt that took place in Lisbon, on the night of 19 October 1921, became known. During the day, a coup led António Granjo's government to resign, but President António José de Almeida resisted appointing the rebels' government. During the night, a riot led by a "ghost truck" led by Abel Olímpio resulted in five people associated with the Sidonist regime being killed and one being gravely injured.
