Charles III (13 June 839 – 13 January 888), also known as Charles the Fat, was the Carolingian Emperor from 881 to 888.
 The youngest son of Louis the German and Hemma, Charles was a great-grandson of Charlemagne.
 He was the second-last emperor of the Carolingian dynasty and the last to rule, briefly, over a re-united Frankish empire.
Otbert (Latin Otbertus, Italian Oberto; died after 1014) was Margrave of Milan.
 A member of the Obertenghi family, he succeeeded his father, Otbert I, as margrave after his father's death in 975, together with his brother Adalbert.
 He was also count of Milan, Genoa, and Bobbio.
 In 1002, he joined Arduin's revolt against Henry II, Holy Roman Emperor.
Sa'id ibn Makhlad (died 889) was a senior official of the Abbasid Caliphate.
 Born a Nestorian Christian, he converted to Islam and served as a secretary in the Abbasid capital, Baghdad.
 He rose to prominence during the regency of al-Muwaffaq over his brother, the Caliph al-Mu'tamid (r. 870–892): between 878 and 885, he served as "de facto" vizier of the Caliphate, although he did not bear the title.
 His valuable assistance to al-Muwaffaq was recognized in 882 by the award of the unique honorific title Dhu'l-Wizaratayn ("possessor of the two vizierates"), with which he appears even on coins.
 However, the activities of his brother, Abdun, who had remained a Christian and tried to obtain concessions for the Christian subjects of the Caliphate, brought about his sudden fall from power in 885.
 He died in 889.
Bernard Plantapilosa (22 March 841 – 886), or Plantevelue, son of Bernard of Septimania and Dhuoda, was the Count of Auvergne (as Bernard II) from 872 to his death.
 The Emperor Charles the Fat granted him the title of Margrave of Aquitaine in 885.
Bernard IV, Margrave of Baden-Durlach (born: 1517; died: 20 January 1553) was Margrave of Baden-Pforzheim from 26 September 1552 until his death.
Beggo (died 28 October 816) was the son of Gerard I of Paris.
 He was appointed Count of Toulouse, Duke of Septimania, Duke of Aquitaine, and Margrave of the Hispanic March in 806 and followed his father as Count of Paris in 815.
Acfred (also Acfredus, Egfridus, Ecfrid or Effroi) was the Count of Toulouse from 842 to 843.
 When Charles the Bald deposed Bernard of Septimania in 842, he installed Acfred in Toulouse in July.
 The next year, however, Bernard, allied with Pepin II of Aquitaine, expelled Acfred.
 He never regained his county.
 Acfred's deposition was not recognised by the king until 844 or 845, when, having defeated and executed Bernard, he appointed Fredelon count of Toulouse.
 Perhaps Acfred had died by then, but perhaps not.
William (died 10 September 1056) was the Margrave of the Nordmark from 1051 until his death.
 He was the eldest son and successor of the Margrave Bernard by a daughter of Vladimir the Great.
 He died fighting the Slavs in the Battle of Pritzlawa.
 Upon his death, he was succeeded by his half-brother Otto as Margrave of the Nordmark.
Li Congke () (11 February 885 – 11 January 937), also known posthumously as Emperor Mo of Later Tang (後唐末帝, "last emperor of Later Tang"), Emperor Fei of Later Tang (後唐廢帝, "deposed emperor of Later Tang"), Wang Congke (王從珂) (particularly during succeeding Later Jin, which did not recognize him as a legitimate Later Tang emperor), or Prince of Lu (潞王, a title Li Congke carried prior to his reign), nickname Ershisan (二十三, "23") or, in short, Asan (阿三), was the last emperor of the Later Tang - the second of the Five Dynasties following the fall of the Tang Dynasty.
 He was an adoptive son of Li Siyuan (Emperor Mingzong) and took the throne after overthrowing Emperor Mingzong's biological son Emperor Min of Later Tang (Li Conghou).
 He was later himself overthrown by his brother-in-law Shi Jingtang, who was supported by Khitan troops (and whose Later Jin succeeded his).
 When the combined Later Jin and Khitan forces defeated Later Tang forces, Li Congke and his family members, as well as the guards most loyal to him, ascended a tower and set it on fire, dying in the fire.
