In 1828, the Azorean island of Terceira was taken by the Portuguese Liberals in an event that triggered the Liberal Wars, a civil conflict that opposed the Liberal party headed by the ex-King Peter IV (Emperor Peter I of Brazil) to the Miguelite party headed by his brother King Michael I. The city of Angra at the Terceira, became then the provisional capital of the Regency Council headed by the prominent count of Vila Flor (future first duke of Terceira), governing in the name of the Queen Mary II, daughter of Peter IV.
