The Vintist movement started after the revolution of 24 August 1820 that swiftly replaced the protectorate of William Beresford with a Provisional Junta and Constituent Assembly composed of diplomatic functionaries, merchants, agrarian burghers, and university-educated representatives who were usually lawyers. Vintism ended with the "Vilafrancada" on 27 May 1823, a military uprising led by Prince Miguel that led to the abolishment of the 1822 Constitution and the reestablishment of absolute monarchy.
