Liberal Wars in the context of "Angra do Heroísmo"

The Empire of Brazil (Portuguese: Império do Brasil) was a 19th-century state that broadly comprised the territories which form modern Brazil and Uruguay until the latter achieved independence in 1828. The empire's government was a representative parliamentary constitutional monarchy under the rule of Emperors Pedro I and his son Pedro II. A colony of the Kingdom of Portugal, Brazil became the seat of the Portuguese Empire in 1808, when the Portuguese Prince regent, later King Dom John VI, fled from Napoleon's invasion of Portugal and established himself and his government in the Brazilian city of Rio de Janeiro. John VI later returned to Portugal, leaving his eldest son and heir-apparent, Pedro, to rule the Kingdom of Brazil as regent. On 7 September 1822, Pedro declared the independence of Brazil and, after waging a successful war against his father's kingdom, was acclaimed on 12 October as Pedro I, the first Emperor of Brazil. The new country was huge, sparsely populated, and ethnically diverse.

Unlike most of the neighboring Hispanic American republics, Brazil had political stability, vibrant economic growth, constitutionally guaranteed freedom of speech, and respect for civil rights of its subjects, albeit with legal restrictions on women and slaves, the latter regarded as property and not citizens. The Empire's bicameral parliament was elected under comparatively democratic methods for the era, as were the provincial and local legislatures. This led to a long ideological conflict between Pedro I and a sizable parliamentary faction over the role of the monarch in the government. He also had to face other obstacles. The unsuccessful Cisplatine War against the neighboring United Provinces of the Río de la Plata in 1828 led to the secession of the province of Cisplatina (later to become Uruguay). In 1826, despite his role in Brazilian independence, he became the king of Portugal; he abdicated the Portuguese throne in favor of Maria, his eldest daughter. Two years later, she was usurped by Pedro I's younger brother Miguel. Unable to deal with both Brazilian and Portuguese affairs, Pedro I abdicated his Brazilian throne on 7 April 1831 and immediately departed for Europe to restore his daughter to the Portuguese throne.

Dona Maria II (Maria da Glória Joana Carlota Leopoldina da Cruz Francisca Xavier de Paula Isidora Micaela Gabriela Rafaela Gonzaga de Habsburgo-Lorena e Bragança; 4 April 1819 – 15 November 1853) also known as "the Educator" (Portuguese: "a Educadora") or as "the Good Mother" (Portuguese: "a Boa Mãe"), was Queen of Portugal from 1826 to 1828, and again from 1834 to 1853. Her supporters considered her to be the rightful queen also during the period between her two reigns.

Maria was born in Rio de Janeiro during the reign of her paternal grandfather, King Dom João VI. She was the first child of the Duke and Duchess of Braganza, who later became Emperor Dom Pedro I and Empress Dona Maria Leopoldina of Brazil. In 1826, her father became king of Portugal but quickly abdicated in favour of the seven-year-old Maria. Both Pedro and Maria remained in Brazil, and her aunt Dona Isabel Maria initially served as regent for them in Portugal. Later Emperor Pedro's brother Miguel replaced Isabel Maria as regent and was to marry Maria when she came of age. However, a few months after Miguel's arrival in Portugal in early 1828 he deposed the absent Maria and declared himself king, thus beginning the Liberal Wars over royal succession. Maria remained outside Portugal throughout her first reign, finally arriving in Gibraltar just in time to learn of her deposition. She proceeded to England and then returned to Brazil. In 1831 her father (having abdicated the Brazilian throne) returned to Europe with his daughter and led a military expedition in support of Maria's claim while she pursued her education in France. She finally set foot in Portugal for the first time in 1833 after Lisbon was occupied by forces supporting her. In 1834, Miguel was forced to abdicate and Maria was restored as undisputed queen. She remained a member of the Brazilian imperial family until 1835 when she was excluded from the Brazilian line of succession by law.

Dom Miguel I (26 October 1802 – 14 November 1866), known by several nicknames, was the King of Portugal between 1828 and 1834. He was the son of King John VI and Queen Carlota Joaquina.

Following his exile as a result of his actions in support of absolutism in the April Revolt (Abrilada) of 1824, Miguel returned to Portugal in 1828 as regent and fiancé of his niece who was Queen Maria II. As regent, he claimed the Portuguese throne in his own right, since according to the so-called Fundamental Laws of the Kingdom his older brother Pedro IV and therefore the latter's daughter had lost their rights from the moment that Pedro had made war on Portugal and become the sovereign of a foreign state (Brazilian Empire). This led to a difficult political situation, during which many people were killed, imprisoned, persecuted or sent into exile, and which culminated in the Portuguese Liberal Wars between authoritarian absolutists and progressive constitutionalists. In the end, Miguel was forced out from the throne and lived the last 32 years of his life in exile.

Admiral Sir Charles John Napier KCB (6 March 1786 – 6 November 1860) was a British naval officer whose sixty years in the Royal Navy included service in the War of 1812, the Napoleonic Wars, Syrian War and the Crimean War, and a period commanding the Portuguese navy in the Liberal Wars. An innovator concerned with the development of iron ships, and an advocate of humane reform in the Royal Navy, he was also active in politics as a Liberal Member of Parliament and was probably the naval officer most widely known to the public in the early Victorian Era.

The history of the kingdom of Portugal and the Algarves, from the First Treaty of San Ildefonso and the beginning of the reign of Queen Maria I in 1777, to the end of the Liberal Wars in 1834, spans a complex historical period in which several important political and military events led to the end of the absolutist regime and to the installation of a constitutional monarchy in the country.

In 1807, Napoleon ordered the invasion of Portugal and subsequently the royal family and its entire court migrated to Brazil, Maria I declaring the United Kingdom of Portugal, Brazil and the Algarves in 1815. This would be one of the causes for the declaration of Brazilian independence by Pedro I of Brazil in 1822, following a liberal revolution in Portugal.

The April Revolt (Portuguese: Abrilada) was an absolutist political revolt that took place in the United Kingdom of Portugal, Brazil and the Algarves in April 1824. It succeeded the 1823 Vilafrancada and foreshadowed the Liberal Wars which raged from 1828 until 1834.
