Dom (title) in the context of Prefix

Dominus is the Latin word for Lord or owner. Dominus was used primarily as an imperial title during the era of the Roman Empire (25 BC – 1453 AD) and was also the Latin title of the feudal, superior and mesne, lords. Dominus was also used as an ecclesiastical and academic title during thattime. The ecclesiastical title was translated from the French seigneur into English as sir, making it a common prefix for parsons before the Reformation. This is evident by the character's name Sir Hugh Evans in Shakespeare's Merry Wives of Windsor. The title Dominus is still used in modern times for those with a Bachelor of Arts degree.

The shortened form for Dominus – Dom – has remained in use in modern times as a prefix of honor for ecclesiastics of the Catholic Church, and members of religious orders, especially for those of the monastic Order of Saint Benedict, the Benedictines, who have professed perpetual religious vows. The Spanish equivalents of Doñacode: spa promoted to code: es and the French equivalent of Dame are given to nuns of the Benedictine order.

Prince Henry of Portugal, Duke of Viseu (Portuguese: Infante Dom Henrique; 4 March 1394 – 13 November 1460), better known as Prince Henry the Navigator (Portuguese: Infante Dom Henrique, o Navegador), was a Portuguese prince and a central figure in the early days of the Portuguese Empire and in the 15th-century European maritime exploration. Through his administrative direction, he is regarded as the main initiator of what would be known as the Age of Discovery. Henry was the fourth child of King John I of Portugal, who founded the House of Aviz.

After procuring the new caravel ship, Henry was responsible for the early development of Portuguese exploration and maritime trade with other continents through the systematic exploration of Western Africa, the islands of the Atlantic Ocean, and the search for new routes. He encouraged his father to conquer Ceuta (1415), the Muslim port on the North African coast across the Straits of Gibraltar from the Iberian Peninsula. He learned of the opportunity offered by the Saharan trade routes that terminated there, and became fascinated with Africa in general; he was most intrigued by the Christian legend of Prester John and the expansion of Portuguese trade. He is regarded as the patron of Portuguese exploration. He is also considered to be one of the most responsible for developing the slave trade in Western Europe. The prince died on 13 November 1460 in Vila do Bispo, Algarve.

Dona Maria Leopoldina of Austria (22 January 1797 – 11 December 1826) was the first Empress of Brazil as the wife of Emperor Dom Pedro I from 12 October 1822 until her death. She was also Queen of Portugal during her husband's brief reign as King Dom Pedro IV from 10 March to 2 May 1826.

She was born in Vienna, Austria, the daughter of Holy Roman Emperor Francis II, and his second wife, Maria Theresa of Naples and Sicily. Among her many siblings were Emperor Ferdinand I of Austria and Marie Louise, Duchess of Parma, the wife of Napoleon Bonaparte.

Abdication is the act of formally relinquishing monarchical authority. Abdications have played various roles in the succession procedures of monarchies. While some cultures have viewed abdication as an extreme abandonment of duty, in other societies (such as pre-Meiji Restoration Japan), abdication was a regular event and helped maintain stability during political succession.

Historically, abdications have occurred both by force (where the regnant was dethroned, thus forced to abdicate on pain of death or other severe consequences) and voluntarily. Some rulers are deemed to have abdicated in absentia, vacating the physical throne and thus their position of power, although these judgements were generally pronounced by successors with vested interests in seeing the throne abdicated, and often without or despite the direct input of the abdicating monarch.

Confederados (Portuguese pronunciation: [kõfedeˈɾadus]) is the Brazilian name for Confederate expatriates, all white Southerners who fled the Southern United States during Reconstruction, and their Brazilian descendants. They were enticed to Brazil by offers of cheap land from Emperor Dom Pedro II, who had hoped to gain expertise in cotton farming. The regime in Brazil had a number of features that attracted the Confederados, namely the continued legality of slavery, but also political decentralization and a relatively high commitment to free trade.

It is estimated that up to 20,000 American Confederates immigrated to the Empire of Brazil from the Southern United States after the American Civil War. Initially, most settled in the current state of São Paulo, where they founded the city of Americana, which was once part of the neighboring city of Santa Bárbara d'Oeste. The descendants of other Confederados would later be found throughout Brazil.

Dom John VI (Portuguese: João Maria José Francisco Xavier de Paula Luís António Domingos Rafael; 13 May 1767 – 10 March 1826), known as "the Clement" (o Clemente), was King of the United Kingdom of Portugal, Brazil and the Algarves from 1816 to 1825, and after the recognition of Brazil's independence, titular Emperor of Brazil and King of Portugal until his death in 1826.

John VI was born in Lisbon during the reign of his maternal grandfather, King Dom Joseph I of Portugal. He was the second son of the Princess of Brazil and Infante Peter of Portugal, who later became Queen Dona Maria I and King Dom Peter III. In 1785, John married Carlota Joaquina of Spain, with whom he had nine children. He became heir to the throne when his older brother, Prince José, died of smallpox in 1788. Before his accession to the throne, John bore the titles Duke of Braganza, Duke of Beja, and Prince of Brazil. From 1799, he served as prince regent due to his mother's mental illness. In 1816, he succeeded his mother as monarch of the Portuguese Empire, with no real change in his authority, since he already possessed absolute powers as regent.

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.

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.

Dona Isabel (29 July 1846 – 14 November 1921), called "the Redemptress", was the Princess Imperial (heiress presumptive to the throne) of the Empire of Brazil and the Empire's regent on three occasions. Born in Rio de Janeiro as the eldest daughter of Emperor Pedro II of Brazil and Empress Teresa Cristina, she was a member of the Brazilian branch of the House of Braganza (Portuguese: Bragança). After the deaths of her two brothers in infancy, she was recognized as her father's heiress presumptive. She married a French prince, Gaston, Count of Eu, in an arranged marriage and they had three sons.

During her father's absences abroad, Isabel acted as regent. In her third and final regency, she actively promoted and ultimately signed a law, named Lei Áurea or the Golden Law, emancipating all slaves in Brazil. Even though the action was broadly popular, there was strong opposition to her succession to the throne. Her gender, strong Catholic faith, and marriage to a foreigner were seen as impediments against her, and the emancipation of the slaves generated dislike among powerful planters. In 1889, her family was deposed in a military coup, and she spent the last 30 years of her life in exile in France.

Princess Leopoldina of Brazil (Leopoldina Teresa Francisca Carolina Miguela Gabriela Rafaela Gonzaga; 13 July 1847 – 7 February 1871) was the daughter of Emperor Pedro II and Empress Teresa Cristina. She shared the first name of her paternal grandmother, Empress Maria Leopoldina of Brazil.

A Princess of Brazil from birth, Dona Leopoldina renounced her titles upon her marriage to Prince Ludwig August of Saxe-Coburg and Gotha, taking the title of Princess of Saxe-Coburg and Gotha and Duchess of Saxony.

Dona Francisca (2 August 1824 – 27 March 1898) was a princess of the Empire of Brazil (as daughter of Emperor Dom Pedro I, who also reigned as King Dom Pedro IV of Portugal, and his first wife Maria Leopoldina of Habsburg), who became Princess of Joinville upon marrying François d’Orléans, son of the French king Louis Philippe I. The couple had three children. Through their oldest daughter, Francisca and François are the ancestors of Jean, Count of Paris, the present Orléanist pretender to the French throne.

Dona Maria I (Maria Francisca Isabel Josefa Antónia Gertrudes Rita Joana; 17 December 1734 – 20 March 1816) also known as Maria the Pious in Portugal and Maria the Mad in Brazil, was Queen of Portugal from 24 February 1777 until her death in 1816. Maria was the first undisputed queen regnant of Portugal and the first monarch of Brazil.

Maria was the eldest daughter of King Dom José I (Joseph I) of Portugal and Queen Mariana Victoria. As the heir to the throne, she held the titles of Princess of Brazil and Duchess of Braganza. She married her uncle Infante Pedro (Peter) in 1760. They had six children, of whom three survived infancy: José, João (John), and Mariana Vitória. The death of King José in 1777 placed Maria, then 42 years old, on the throne. Her husband Pedro was nominally king alongside her as Dom Pedro III.

Dom Ferdinand II (German: Ferdinand August Franz Anton Koháry von Sachsen-Coburg-Gotha; 29 October 1816 – 15 December 1885), also known as Ferdinand of Saxe-Coburg and Gotha and as "the King-artist" (Portuguese: o Rei-Artista), was King of Portugal from 16 September 1837 to 15 November 1853 as the husband and co-ruler of Queen Maria II.

In keeping with Portuguese law, Ferdinand only became king after the birth of his first son, Prince Pedro, in 1837. Ferdinand's reign came to an end with the death of his wife in 1853, but he served as regent for his son and successor, King Pedro V, until 1855.
