of Prince D. Miguel's uprisings supported by several other people of traditionalist and absolutist leanings, against the liberalism adopted by his father D. João VI in the later phase of his rule. Conspiracy of Elvas (1823) The Abrilada (1824) On 30 April 1824, Prince D. Miguel rose again against his father. The King took refuge aboard the British ship Windsor Castle, with the aid of the Portuguese diplomatic corp, while grandes of the kingdom like the Duke of Palmela were arrested in Belém, being then moved to imprisonment in Peniche, with the then intendent-general of police Baron of Rendufe being persecuted by the Miguelist rise-up, which then turned its attentions to the Count of Vila Flor (later more famous for his future title of Duke of Terceira) and the Count of Paraty. The reactionary philosopher José Agostinho de Macedo was one of the leaders of the rallying up of support among the masses for the movement, denouncing the prisoners the movement made at political rallies. On 13 May, D. Miguel was finally forced to leave for exile on board the frigate Pérola towards France, while on the following day D. João returned to Bemposta, and impeached the brutal pro-Miguelist Minister of Justice José António de Oliveira Leite de Barros, replacing him by Friar Patrício da Silva, and the Duke of Palmela was promoted to Minister of the Kingdom.

Over the next 25 years the fledgling Portuguese democracy experienced several military upheavals, especially the Liberal Wars fought between the brothers Dom Pedro, ex-Emperor of Brazil and the absolutist usurper Dom Miguel. To assert the cause of the rightful Queen, his daughter Maria da Glória, Pedro sailed from Terceira in the Azores with an expeditionary force consisting of 60 vessels, 7500 men including the Count of Vila Flor, Alexandre Herculano, Almeida Garrett, Joaquim António de Aguiar, José Travassos Valdez and a volunteer British contingent under the command of Colonels George Lloyd Hodges and Charles Shaw and effected a Landing at Mindelo
