 These liberals were motivated by the movements in Spain, where in August 1836, a revolt by military officers (the "Motín de La Granja de San Ildefonso") forced the reinstatement of the 1812 Cadiz Constitution.Ultimately, on 9 September 1836 a revolution in Lisbon by the politicized population and the National Guard to drive the "Cartistas" (Chartists) from power forced Queen Maria II to reinstate the 1822 Constitution.Members of the government installed following the revolution were known as "Setembristas", after their short-lived movement, the "Setembrismo", which was launched in September.
