Ptolemy XIV of Egypt: Ptolemy XIV (Greek: Πτολεμαῖος , "Ptolemaĩos", who lived 60 BC/59 BC–44 BC and reigned 47 BC–44 BC), was a son of Ptolemy XII of Egypt and one of the last members of the Ptolemaic dynasty of Egypt.  Following the death of his older brother Ptolemy XIII of Egypt on January 13, 47 BC, he was proclaimed Pharaoh and co-ruler by their older sister and remaining Pharaoh, Cleopatra VII of Egypt.  He and Cleopatra were married, but Cleopatra continued to act as lover of Roman dictator Julius Caesar.  Ptolemy is considered to have reigned in name only, with Cleopatra keeping actual authority to herself.  On March 15, 44 BC Caesar was murdered in Rome by a group of conspirators whose most notable members were Marcus Junius Brutus and Gaius Cassius Longinus.  Ptolemy soon followed him in death.  An inscription mentioning him as alive was dated at July 26, 44 BC.  It has been assumed but remains uncertain that Cleopatra poisoned her co-ruler, with aconite, to replace him with his nephew Ptolemy XV Caesarion, her son by Caesar who was proclaimed co-ruler on September 2, 44 BC and whom his mother intended to support as successor of his father.

Ariarathes VIII of Cappadocia: Ariarathes VIII Epiphanes (Ancient Greek: Ἀριαράθης Ἐπιφανής , Ariaráthēs Epiphanḗs; reigned c. 101–c. 96 BC and in 95 BC), King of Cappadocia, was the second son of Ariarathes VI of Cappadocia and wife Laodice of Cappadocia.  Ariarathes VIII had an older sister called Nysa and an older brother called Ariarathes VII of Cappadocia.

Sen Soulintha: Sen Soulintha, Saen Surintha or Sen Sourintha (1511–1582) was born Chane Tian and became King of Lan Xang reigning 1571-1575 and again 1580-1582.  Sen Soulintha was not of noble birth, rising from royal page to King Setthatirath’s Chief Minister.  During the succession disputes in the Kingdom of Lan Na between King Setthatirath and King Mekuti, Sen Soulintha served Setthatirath as a general and successfully took several cities of Lan Na including Chiang Saen for which he was given the honorific name "Lusai" meaning “victory.”  Sen Soulintha supported Setthatirath in leading the guerrilla campaigns during the Burmese invasions of King Bayinnaung.  When Setthatirath died near Attapeu under suspicious circumstances in 1572, Sen Soulintha led the armies of Lan Xang back to Vientiane.  A succession dispute erupted, which nearly led to civil war and provided a pretext for another Burmese invasion ordered by Bayinnaung and led by the Chief Minister Binnya Dala.  Sen Soulintha defeated the Burmese and Lan Na forces led by Binnya Dala, an event which led to the latter’s exile, only to face a more massive invasion led by Bayinnaug the following year.  Sen Soulintha again attempted to resort to guerilla tactics, but lacked popular support from his seizure of the throne.  He and his son Ong Lo (Nakhon Noi) were captured by Bayinnaung and exiled to Pegu.  The Burmese placed Setthathirath’s brother, and former "Ouphahat" or Viceroy, Prince Tha Heua on the throne.  According to the Luang Prabang chronicles it was this brother, who had led a rebellion in Luang Prabang and tried to seize the throne from Setthathirath on the death of their father Photisarath.  Prince Tha Heua took the regnal name Voravongsa and reigned under Burmese suzerainty from 1575-1579.  Voravongsa was never popular, and drowned with his family while attempting to flee Vientiane in the face of popular uprising.  In 1579, Bayinnaung dispatched a sizable army to restore order.  According to Lao histories Sen Soulintha was then installed as king a second time in 1580.  By that time Sen Soulintha was an old man and reigned only for two years before his son ascended the throne as Nakhon Noi and another succession dispute ensued.

Vologash: Wolgash or Vologash was a king of Hatra, an ancient city in nowadays Iraq.  He is known from more than 20 inscriptions found at Hatra and reigned from about AD 140 to 180.  He was the son of Naṣru who reigned from about AD 128 to 140.  He was one of the first rulers of Hatra calling himself "mlk" ("king"), but he bears also the title "mry' " ("lord").  Both titles are also attested for his brother Sanatruq I.  It is unclear whether they both reigned together and took the title "king" at some point in their reign, or whether Sanatruq succeeded Wolgash.  His successor was either his brother or his nephew Abdsamiya.

Napoléon Louis Bonaparte: Napoléon-Louis Bonaparte (11 October 1804 – 17 March 1831), also known as Louis II of Holland, was the middle son of Louis I of Holland and Hortense de Beauharnais.  His father was the younger brother of Napoléon I and reigned as King of Holland from 1806 to 1810, while his mother was the daughter of Josephine de Beauharnais, Napoléon's first wife.  He was the older brother of Louis Napoleon Bonaparte, future Emperor Napoleon III.

Yeongjo of Joseon: Yeongjo of Joseon (31 October 1694 – 22 April 1776, reigned 16 October 1724 – 22 April 1776) was the 21st king of the Korean Joseon Dynasty.  He was the second son of King Sukjong.  His mother was Consort Suk of the Choe clan.  Before ascending to power, his name was Prince Yeoning.  In 1720, a few months after the accession of his older brother, King Gyeongjong as the 20th King, Yeoning became the Royal Prince Successor Brother (wangseje, 왕세제).  This induced a large controversy between political factions.  Nevertheless, four years later, at the death of Gyeongjong, Yeongjo ascended the throne.

Edward II of England: Edward II (25 April 1284 – 21 September 1327), also called Edward of Caernarfon, was King of England from 1307 until he was deposed in January 1327.  The fourth son of Edward I, Edward became the heir to the throne following the death of his older brother Alphonso.  Beginning in 1300, Edward accompanied his father on campaigns to pacify Scotland, and in 1306 he was knighted in a grand ceremony at Westminster Abbey.  Edward succeeded to the throne in 1307, following his father's death.  In 1308, he married Isabella of France, the daughter of the powerful King Philip IV, as part of a long-running effort to resolve the tensions between the English and French crowns.

Roger Hillary: Sir Roger Hillary (died 1356) was an English justice.  He was one of five sons of William Hillary and his wife Agnes, a landowning family which held properties in Lincolnshire, Warwickshire, Staffordshire, and Leicestershire, and appear to have been related to Sir William Bereford, the Chief Justice of the Common Pleas; a useful connection for a nascent lawyer.  In 1310 Hillary was recorded as a court attorney, and in 1324 he was made a Serjeant-at-law.  In the later years of Edward II's reign Hillary kept a low profile.  In spring 1320 he married Katherine, and added to his property portfolio the Manor of Fisherwick near Lichfield in 1327 and a life-grant of a mill at Bentley at around the same time.

He was the older brother of Lord Xinling (Wei Wuji).  In 275 BC, after a Han general fled to the Wei capital Daliang, King Anxi began a war against Qin in an alliance with Qi.  Qin forces under chancellor Wei Ran and general Bai Qi captured 4 cities, besieged Daliang and killed 40,000 people.  In 273 BC, with the assistance of Lord Mengchang of Qi, he began another war in an alliance with Zhao.  The war ended with the deaths of 130,000 people.  In 257 BC, he assisted Zhao when its capital Handan was besieged by Qin forces, at the request of Lord Pingyuan of Zhao, who was married to Xinling's older sister.
