Norodom (Khmer: នរោត្តម ), known previously as Ang Voddey (Khmer: អង្គវតី ) (February 1834 – 24 April 1904), ruled as king of Cambodia from 1860 to 1904.
 He was the eldest son of King Ang Duong, who ruled on the behalf of Siam, and half-brother of Prince Si Votha as well as the half-brother of King Sisowath.
 Norodom was considered to be the first modern Khmer king.
 He was credited with saving Cambodia from disappearing altogether.
 In 1863, to prevent the two powerful neighbours, Vietnam and Siam, from swallowing Cambodia altogether he was invited by France to make Cambodia its protectorate.
 However, he sent many letters to Siam claiming French Admiral de la Grandière had forced him into signing a false treaty.
 Many Cambodians believed that this brilliant act and his shrewdness did actually save Cambodia from disappearing.
 His reign of 43 years is the longest in the modern era.
Strut-Harald ("Cone Harald" from his cone-shaped helmet of gold) was a semi-legendary jarl or petty king who ruled over the Danish territory of Scania (in what is now southern Sweden) during the late 10th century CE (approximately 975-986).
 Norse sagas identify him as the son of Gorm the Old, His Sister being Astrid Wiffen who was married to the Earl Philippus Sigefrid Wiffen of Scania, Strut-Harald was also a half-brother of Harald Bluetooth.
Henry FitzRoy, 1st Duke of Richmond and Somerset (15 June 1519 – 23 July 1536), was the son of King Henry VIII of England and his mistress, Elizabeth Blount, and the only illegitimate offspring whom Henry VIII acknowledged.
 He was the younger half-brother of Queen Mary I, as well as the older half-brother of Queen Elizabeth I and King Edward VI.

Teigue O'Rourke (Irish: "Tadhg Ó Ruairc" ) (1576 - 1605) was the last king of West Breifne from 1603 until his death in 1605.
 He was the son of Brian O'Rourke and Mary Burke of Clanricarde.
 Raised by his mother in County Galway, he lived most of his life in exile from his kingdom, looking for allies to support his claim as king of West Breifne in opposition to his half-brother Brian Oge O'Rourke.
 Having initially supported the Irish alliance during the Nine Years' War, he switched allegiance to England following the Battle of Kinsale in 1602.
 With the support of English forces he invaded West Breifne in 1603, ousting his half-brother and ruling as king until his unexpected death in late 1605 at the age of 28.
Suleiman Mirza (Persian: سلیمان میرزا‎ , "Soleymān Mirzā " ‎ ; b. 28 March 1554, Nakhchivan – d. 30 October 1576) was a Safavid prince.
 The son of king Tahmasp I (r. 1524–1576) by his Circassian wife Sultan-Agha Khanum, he functioned several years as an official, serving as the governor ("hakem") of Shiraz (1555–1557/58, under a "laleh") and Mashhad (1567–1573, under a "laleh" as well).
 His full sister was Pari Khan Khanum, and his Circassian uncle Shamkhal Sultan – both extremely pivotal figures in Safavid affairs during the latter half of the 16th century.
 During the last few years of Tahmasp I's life, when a protracted competition for the throne, as well as much jockeying for position by the rival factions was evident, a number of Qizilbash chiefs in 1574 openly supported Suleiman Mirza in order for him to succeed Tahmasp to the throne.
 When his half-brother Ismail Mirza Safavi (who succeeded as Ismail II) was enthroned on 22 August 1576, the latter ordered for the systematic murder or blinding of any prince of royal blood who could become the center of a conspiracy against him.
 As a result of this, Suleiman Mirza was killed on 30 October 1576 by the order of his own half-brother.
 He was buried at the Shrine of Imamzadeh Hossein in Qazvin, the then royal capital.
Muiz ud-Din Bahram (r. 1240–42) was the sixth sultan of the Mamluk Dynasty (or Slave Dynasty).
 He was the son of Shams ud din Iltutmish (1210–36) by Nadira Begum and was the half-brother of Razia Sultan (1236–40).
 While his sister was in Bathinda, he declared himself king with the support of forty chiefs.
 His sister tried to regain the throne with the aid of her husband Altunia, a chief of Bathinda, though they were eventually arrested and executed.
 Even so, during Muiz ud din Bahram's two years as king, the chiefs that had originally supported him became disordered and constantly bickered among each other.
 It was during this period of unrest that he was murdered by his own army in 1242 (died 15 May 1242).
 After his death, he was succeeded by his nephew Ala ud din Masud, a son of his half-brother Rukn ud din Firuz.
Catherine of Bosnia (Bosnian: "Katarina Tomašević Kotromanić" /Катарина Томашевић Котроманић; born in 1453) was a member of the House of Kotromanić and the last Bosnian princess.
 She was the only daughter of King Thomas and Queen Catherine, who also had a son named Sigismund.
 When Thomas died, in July 1461, the Bosnian crown devolved upon her older half-brother, Stephen Tomašević.
 Catherine and Sigismund are popularly said to have moved at that time with their mother to the castle of Kozograd above Fojnica.
 It is likely, however, that they remained at the royal court in Jajce, being their half-brother's closest heirs.
 In 1463, the Ottomans led by Mehmed the Conqueror invaded Bosnia.
 The royal family apparently decided to split and flee towards Croatia proper and the coast in different directions to confuse and mislead the invaders.
 Sigismund and Catherine, separated from their mother, were nevertheless captured in the town of Zvečaj, close to Jajce.
 Their half-brother the King was deceived into surrendering in Ključ, and was executed shortly afterwards.
 Queen Catherine succeeded in escaping and eventually settled in Rome.
Jean de Dunois (23 November 1402 – 24 November 1468), also called John of Orléans and Jean de Duno ("Jean d'Orléans"), was the illegitimate son of Louis I, Duke of Orléans, by Mariette d'Enghien.
 His nickname, the "Bastard of Orléans" ("bâtard d'Orléans"), was a term of respect, since it acknowledged him as a first cousin to the king and acting head of a cadet branch of the royal family during his half-brother's captivity.
 In 1439 he received the county of Dunois from his half-brother, Charles, Duke of Orléans, and later king Charles VII made him count of Longueville.
