John IV of Portugal in the context of "Catherine of Braganza"

"O Come, All Ye Faithful", also known as "Adeste Fideles", is a Christmas carol that has been attributed to various authors, including John Francis Wade (1711–1786), John Reading (1645–1692), King John IV of Portugal (1604–1656), and anonymous Cistercian monks. The earliest printed version is in a book published by Wade. A manuscript by Wade, dating to 1751, is held by Stonyhurst College in Lancashire.

The original four verses of the hymn were extended to a total of eight, and these have been translated into many languages. In 1841, the English Catholic priest Frederick Oakeley translated the hymn into English as "O Come All Ye Faithful", which became widespread in English-speaking countries.

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.

Philip IV (Spanish: Felipe Domingo Victor de la Cruz de Austria y Austria, Portuguese: Filipe III; 8 April 1605 – 17 September 1665), also called the Planet King (Spanish: Rey Planeta), was King of Spain from 1621 to his death and (as Philip III) King of Portugal from 1621 to 1640. Philip is remembered for his patronage of the arts, including such artists as Diego Velázquez, and his rule over Spain during the Thirty Years' War.

By the time of his death, the Spanish Empire had reached approximately 12.2 million square kilometres (4.7 million square miles) in area but in other aspects was in decline, a process to which Philip contributed with his inability to achieve successful domestic and military reform. He was succeeded on his death by his young son Charles II as King of Spain and in 1640 (with the collapse of the Iberian Union) by John IV as King of Portugal.

The Most Serene House of Braganza (Portuguese: Sereníssima Casa de Bragança), also known as the Brigantine dynasty (dinastia Brigantina), is a dynasty of emperors, kings, princes, and dukes of Portuguese origin which reigned in Europe and the Americas.

The house was founded by Afonso I, 1st Duke of Braganza, illegitimate son of King John I of Portugal of the House of Aviz, and would eventually grow into one of the wealthiest and most powerful noble houses of Iberia during the Renaissance period. The Braganzas came to rule the Kingdom of Portugal and the Algarves after successfully deposing the Philippine Dynasty in the Restoration War, resulting in the Duke of Braganza becoming King John IV of Portugal, in 1640. The Braganzas ruled Portugal and the Portuguese Empire from 1640 and with the creation of the United Kingdom of Portugal, Brazil and the Algarves, in 1815, and the subsequent independence of the Empire of Brazil, in 1822, the Braganzas came to rule as the monarchs of Brazil.

Piper cubeba, cubeb or tailed pepper is a plant in genus Piper, cultivated for its fruit and essential oil. It is mostly grown in Java and Sumatra, hence sometimes called Java pepper. The fruits are gathered before they are ripe, and carefully dried. Commercial cubeb consists of the dried berries, similar in appearance to black pepper, but with stalks attached – the "tails" in "tailed pepper". The dried pericarp is wrinkled, and its color ranges from grayish brown to black. The seed is hard, white and oily. The odor of cubeb is described as agreeable and aromatic and the taste as pungent, acrid, slightly bitter and persistent. It has been described as tasting like allspice, or like a cross between allspice and black pepper.

Cubeb came to Europe via India through the trade with the Arabs. The name cubeb comes from Arabic kabāba (كبابة) by way of Old French quibibes. Cubeb is mentioned in alchemical writings by its Arabic name. In his Theatrum Botanicum, John Parkinson tells that the king of Portugal (Possibly either Philip IV of Spain or John IV of Portugal, as that year was marked by the start of the Portuguese Restoration War) prohibited the sale of cubeb to promote black pepper (Piper nigrum) around 1640. It experienced a brief resurgence in 19th-century Europe for medicinal uses, but has practically vanished from the European market since. It continues to be used as a flavoring agent for gins and cigarettes in the West, and as a seasoning for food in Indonesia.

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.

The Bombay Presidency, officially called the Presidency of Bombay until 1937, later the Bombay Province, also called Bombay and Sind (1843–1936), was an administrative subdivision (province) of British India, with its capital in the city that came up over the seven islands of Bombay. The first mainland territory was acquired in the Konkan region with the Treaty of Bassein. Poona was the summer capital.

The Bombay Province has its beginnings in the city of Bombay that was leased in fee tail to the East India Company, via the Royal Charter of 27 March 1668 by King Charles II of England, who had in turn acquired Bombay on 11 May 1661, through the dowry by way of his marriage treaty with princess Catherine De Braganza, daughter of John IV of Portugal. The English East India Company transferred its Western India headquarters from Surat in the Gulf of Cambay after it was sacked, to the relatively safe Bombay Harbour in 1687. The province was brought under direct rule along with other parts of British India through Pitt's India Act, after the nationalisation of the East India Company. Major territorial acquisitions were made by the company after Anglo-Maratha Wars when the whole of the Peshwa's dominions and much of the Gaekwad's sphere of influence were annexed to the Bombay Presidency in stages up until 1818. Aden including Socotra were placed under Bombay in 1839, Sind was annexed by the company in 1843 after defeating the Talpur dynasty in the Battle of Hyderabad.

The Marriage Treaty, or Anglo-Portuguese Treaty, was a treaty of alliance that was agreed between the Kingdom of England and the Kingdom of Portugal and concluded on 23 June 1661.

It led to the marriage of Charles II of England and Catherine of Braganza, the daughter of John IV of Portugal. It was a marriage of state, as was common in the era.
