King of Portugal in the context of "Philip IV of Spain"

Philip II (21 May 1527 – 13 September 1598), sometimes known in Spain as Philip the Prudent (Spanish: Felipe el Prudente), was King of Spain from 1556, King of Portugal from 1580, and King of Naples and Sicily from 1554 until his death in 1598. He was also jure uxoris King of England and Ireland from his marriage to Queen Mary I in 1554 until her death in 1558. Further, he was Duke of Milan from 1540. From 1555, he was Lord of the Seventeen Provinces of the Netherlands.

The son of Emperor Charles V and Isabella of Portugal, Philip inherited his father's Spanish Empire in 1556, and succeeded to the Portuguese throne in 1580 following a dynastic crisis, forming the Iberian Union. The Spanish conquests of the Inca Empire and of the Philippines, named in his honour by Ruy López de Villalobos, were completed during his reign. He finished building the royal palace El Escorial in 1584. Under Philip II, Spain reached the height of its influence and power, advancing into the Spanish Golden Age, and ruled territories in every continent then known to Europeans. Deeply devout, Philip saw himself as the defender of Catholic Europe against the Ottoman Empire and the Protestant Reformation, and invested Spain's position as the leading European power in multiple simultaneous warring efforts.

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.

Sebastian (Portuguese: Sebastião I [sɨβɐʃˈti.ɐ̃w]; 20 January 1554 – 4 August 1578) was King of Portugal from 11 June 1557 to 4 August 1578 and the penultimate Portuguese monarch of the House of Aviz.

He was the son of João Manuel, Prince of Portugal, and Joanna of Austria. He was the grandson of King John III of Portugal and Catherine of Austria, Queen of Portugal. He disappeared (presumably killed in action) in the battle of Alcácer Quibir, against the Saadi Sultanate of Morocco. Sebastian I is often referred to as the Desired (Portuguese: o Desejado) or the Hidden (o Encoberto), as the Portuguese people longed for his return to end the decline of Portugal that began after his death. He is considered to be the Portuguese example of the King asleep in mountain legend as Portuguese tradition states his return, in a foggy dawn, in Portugal's greatest hour of need.

The Portuguese House of Burgundy (Portuguese: Casa de Borgonha) was a Portuguese noble house that ruled the County and later Kingdom of Portugal from its founding until the 1383–85 Portuguese Interregnum.

The house was founded by Henry of Burgundy, who became Count of Portugal in 1096. His son, Afonso Henriques, was proclaimed King of Portugal following his victory at the Battle of Ourique in 1139, establishing the Afonsine dynasty (Dinastia Afonsina). Burgundian monarchs would rule Portugal through much of its early formation, including the formalization of the Portuguese language under King Dinis I, the first Portuguese parliament, under King Afonso II, and the conquest of the Kingdom of the Algarve, under King Afonso III. Numerous princes of the house took up thrones across Europe, such as Ferdinand I, Count of Flanders and Peter I, Count of Urgell. Similarly, many princesses became royal consorts, including Berengaria, Queen of Denmark, Leonor, Queen of Aragon, and Teresa, Duchess of Burgundy, among others.

John I (Portuguese: João [ʒuˈɐ̃w̃]; 11 April 1357 – 14 August 1433), also called John of Aviz, was King of Portugal from 1385 until his death in 1433. He is recognized chiefly for his role in Portugal's victory in a succession war with Castile, preserving his country's independence and establishing the Aviz (or Joanine) dynasty on the Portuguese throne. His long reign of 48 years, the most extensive of all Portuguese monarchs, saw the beginning of Portugal's overseas expansion. John's well-remembered reign in his country earned him the epithet of Fond Memory (de Boa Memória).

The Treaty of Rio de Janeiro is the treaty between the Kingdom of Portugal and the Empire of Brazil, signed August 29, 1825, which recognized Brazil as an independent nation, formally ending the Brazilian War of Independence.

The treaty was ratified by the Emperor of Brazil on August 24, 1825, and by the King of Portugal on November 15, 1825, and on that same date the two instruments of ratification were exchanged between Brazilian and Portuguese diplomats in Lisbon.

Dom Pedro II (Peter II; 26 April 1648 – 9 December 1706), nicknamed the Pacific (Português: o Pacífico) was King of Portugal from 1683 until his death, previously serving as regent for his brother Afonso VI from 1668 until his own accession. He was the fifth and last child of John IV and Luisa de Guzmán.

Dom John V (Portuguese: João Francisco António José Bento Bernardo; 22 October 1689 – 31 July 1750), known as the Magnanimous (o Magnânimo) and the Portuguese Sun King (o Rei-Sol Português), was King of Portugal from 9 December 1706 until his death in 1750. His reign saw the rise of Portugal and its monarchy to new levels of prosperity, wealth, and prestige among European courts.

John V's reign saw an enormous influx of gold into the coffers of the royal treasury, supplied largely by the royal fifth (a tax on precious metals) that was received from the Portuguese colonies of Brazil and Maranhão. John spent lavishly on ambitious architectural works, most notably Mafra Palace, and on commissions and additions for his sizable art and literary collections. Owing to his craving for international diplomatic recognition, John also spent large sums on the embassies he sent to the courts of Europe, the most famous being those he sent to Paris in 1715 and Rome in 1716.
