Political tension rose in the 1820s between constitutionalists or Liberals, (supporters of the constitutional monarchy installed by King John VI of Portugal) and those who supported absolute monarchy. Having embraced the cause of constitutionalism, the local Terceirenses established a "Junta Provisória" in the name of Queen Maria II of Portugal in 1828. Hostilities broke out at the Battle of Praia da Vitória in 1829. In a decree, issued on 15 March 1830, Angra was named as Portuguese capital by the Terceirenses constitutional forces, who protected and supported exiled Liberals who supported the rights of Queen Maria II of Portugal, whose rights were usurped by the "Miguelistas" (supporters of the absolute monarchy of Miguel I). In 1832, Pedro II (former King and regent of Queen Maria) arrived in the Azores to form a government-in-opposition to the absolutionist regime in Lisbon, presided by the Marques of Palmela, and supported by Azoreans Mouzinho da Silveira and Almeida Garrett that developed many important reforms.
