House of Braganza in the context of "Transfer of the Portuguese Court to Brazil"

Dom Pedro I (12 October 1798 – 24 September 1834), known in Brazil and in Portugal as "the Liberator" (Portuguese: o Libertador) or "the Soldier King" (o Rei Soldado) in Portugal, was the founder and first ruler of the Empire of Brazil from 1822 to 1831 (under the name of Pedro I) and King of Portugal in 1826 (under the name of Pedro IV).

Born in Lisbon, Pedro was the fourth child of King Dom John VI of Portugal and Queen Carlota Joaquina, and thus a member of the House of Braganza. When the country was invaded by French troops in 1807, he and his family fled to Portugal's largest and wealthiest colony, Brazil. The outbreak of the Liberal Revolution of 1820 in Lisbon compelled Pedro I's father to return to Portugal in April 1821, leaving him to rule Brazil as regent. He had to deal with challenges from revolutionaries and insubordination by Portuguese troops, all of which he subdued. The Portuguese government's threat to revoke the political autonomy that Brazil had enjoyed since 1808 was met with widespread discontent in Brazil. Pedro I chose the Brazilian side and declared Brazil's independence from Portugal on 7 September 1822. On 12 October, he was acclaimed Brazilian emperor and by March 1824 had defeated all armies loyal to Portugal. A few months later, Pedro I crushed the short-lived Confederation of the Equator, a failed secession attempt by provincial rebels in Brazil's northeast.

The Iberian Union or the Hispanic Monarchy, describes the period from 1580 to 1640 in which the Monarchy of Spain under the Habsburg dynasty, then the personal union of the crowns of Castile and Aragon, brought in personal union also the Kingdom of Portugal. It incorporated the entire Iberian Peninsula except Andorra, as well as Portuguese and Spanish overseas possessions, under the Spanish Habsburg monarchs Philip II, Philip III, and Philip IV. The union began after the Portuguese succession crisis of 1580 and the ensuing War of the Portuguese Succession, and lasted until the Portuguese Restoration War, during which the House of Braganza was established as Portugal's new ruling dynasty with the acclamation of John IV as the new king of Portugal.

As a personal union, the Kingdom of Portugal, the Crown of Castile and the states of the Crown of Aragon remained independent states, sharing only a single monarch. The kings from the Spanish branch of the House of Habsburg were the only element that connected the multiple kingdoms and territories, ruled by the six separate government councils of Castile, Aragon, Portugal, Italy, Flanders-Burgundy, and the Indies. For periods, Portugal maintained a viceroy, appointed by the king, although the turnover was often rapid; in the 60 years of the Union, the country had 13 viceroys and four regency councils (see List of viceroys of Portugal). Similar viceroys were appointed in Aragon, Catalonia, Valencia and other kingdoms of the Union. The governments, institutions, and legal traditions of each kingdom remained independent of one another. Alien laws (Leyes de extranjería) determined that a national of one kingdom was a foreigner in all other kingdoms.

The Restoration War (Portuguese: Guerra da Restauração) between Portugal and Spain began with the Portuguese revolution of 1640 and ended with the Treaty of Lisbon in 1668, bringing a formal end to the Iberian Union.The period from 1640 to 1668 was marked by periodic skirmishes between Portugal and Spain, as well as short episodes of more serious warfare, much of it occasioned by Spanish and Portuguese entanglements with non-Iberian powers. Spain was involved in the Thirty Years' War until 1648 and the Franco-Spanish War until 1659, while Portugal was involved in the Dutch–Portuguese War until 1663.

In the 17th century and afterwards, this period of sporadic conflict was simply known, in Portugal and elsewhere, as the Acclamation War. The war established the House of Braganza as Portugal's new ruling dynasty, replacing the House of Habsburg, which had been united with the Portuguese crown since the 1580 succession crisis.

Catherine of Braganza (Portuguese: Catarina de Bragança; 25 November 1638 – 31 December 1705) was Queen of England, Scotland and Ireland during her marriage to King Charles II, which lasted from 21 May 1662 until his death on 6 February 1685. She was the daughter of John IV of Portugal, who became the first king from the House of Braganza in 1640, after overthrowing the 60-year rule of the Spanish Habsburgs over Portugal. Catherine served as the regent of Portugal during the absence of her brother Peter II in 1701, and again in 1704–1705, after her return to her homeland as a widow.

Owing to her devotion to the Roman Catholic faith in which she had been raised, just like her mother-in-law, Catherine was unpopular in England. She was a special object of attack by the inventors of the Popish Plot. In 1678 the murder of Edmund Berry Godfrey was ascribed to her servants, and Titus Oates accused her of an intention to poison the king. These charges, the absurdity of which was soon shown by cross-examination, nevertheless placed Catherine for some time in great danger. On 28 November 1678, Oates accused Catherine of high treason, and the English House of Commons passed an order for the removal of her and of all Roman Catholics from the Palace of Whitehall. Several further depositions were made against her, and in June 1679 it was decided that she should stand trial, which threat however was lifted by the king's intervention, for which she later showed him much gratitude.

This is a list of Portuguese monarchs who ruled from the establishment of the Kingdom of Portugal, in 1139, to the deposition of the Portuguese monarchy and creation of the Portuguese Republic with the 5 October 1910 revolution.

Through the nearly 800 years in which Portugal was a monarchy, the kings held various other titles and pretensions. Two kings of Portugal, Ferdinand I and Afonso V, claimed the crown of Castile and waged wars in order to enforce their respective claims. Ferdinand I managed to be recognized as King of Galiza in 1369, although his dominance of the region was short-lived. When the House of Habsburg came into power, the kings of Spain, Naples, and Sicily also became kings of Portugal. The House of Braganza brought numerous titles to the Portuguese Crown – some honorary, such as the attribution of the title of Rex Fidelissimus (His Most Faithful Majesty), and royal titles, such as King of Brazil and then de jure Emperor of Brazil.

The monarchs of Brazil (Portuguese: monarcas do Brasil) were the imperial heads of state and hereditary rulers of Brazil from the House of Braganza that reigned from the creation of the Brazilian monarchy in 1815 as a constituent kingdom of the United Kingdom of Portugal, Brazil and the Algarves until the republican coup d'état that overthrew the Empire of Brazil in 1889.

The coast of the territory which would become known as Brazil was first explored by Portuguese navigators on 22 April 1500. This territory was subsequently colonized by the Portuguese crown. Since the transfer of the Portuguese court to Brazil in 1808, colonial rule had de facto ended. On 16 December 1815, Prince Regent John, the future king John VI, raised Brazil to the status of a kingdom, thus making his mother, Maria I, the reigning queen, the first monarch of Brazil. The next year, 20 March 1816, John succeeded his mother as king of the united Luso-Brazilian monarchy. Having proclaimed independence of the Kingdom of Brazil from Portugal in 1822, Pedro I, son of John VI, was acclaimed the first emperor of Brazil on 12 October 1822. He was later succeeded on 7 April 1831 by his son Pedro II, deposed along with the 74-years-old monarchy on 15 November 1889 in a bloodless and unpopular military coup d'état.
