Gunther (Gundahar, Gundahari, Latin "Gundaharius", "Gundicharius", or "Guntharius", Old English "Gūðhere", Old Norse "Gunnarr", anglicised as "Gunnar", d. 437) was a historical King of Burgundy in the early 5th century.
 Legendary tales about him appear in Latin, medieval Middle High German, Old Norse, and Old English texts, especially concerning his relations with Siegfried (Sigurd in Old Norse) and his death by treachery in the hall of Attila the Hun.
Bleda ( ) was a Hunnic ruler, the brother of Attila the Hun.
The history of the Irish language begins with the period from the arrival of speakers of Celtic languages in Ireland to Ireland's earliest known form of Irish, Archaic Irish, which is found in Ogham inscriptions dating from the 3rd or 4th century.
 After the conversion to Christianity in the 5th century, Old Irish begins to appear as glosses and other marginalia in Latin manuscripts, beginning in the 6th century.
 It evolved in the 10th century to Middle Irish.
 Early Modern Irish, otherwise known as Classical Irish, was a literary language that represented a transition between Middle and Modern Irish.
 It was used by writers in both Ireland and Scotland until the 17th century, in the course of which slowly but surely writers began writing in the vernacular dialects, Ulster Irish, Connacht Irish, Munster Irish and Scottish Gaelic.
 As the number of hereditary poets and scribes dwindled under British rule in the early 19th century, Irish became a mostly spoken tongue with little written literature appearing in the language until the Gaelic Revival of the late 19th century.
 The number of speakers was also declining in this period with monoglot and bilingual speakers of Irish increasing adopting only English: while Irish never died out, by the time of the Revival it was largely confined to the less Anglicised regions of the island, which were often also the more rural and remote areas.
 In the 20th and 21st centuries, Irish has continued to survive in Gaeltacht regions and among a minority in other regions.
 It has once again come to be considered an important part of the island's culture and heritage, with efforts being made to preserve and promote it.
Pythagoras of Samos or Pythagoras of Rhegion, (Ancient Greek: Πυθαγόρας , fl.
 5th century BC) was a statuary from Samos whom Pliny the Elder expressly distinguishes from the more renowned Pythagoras from Rhegion.
 Pliny does however say that the sculptor bore a remarkable personal likeness to the mathematician.
 There is no precise indication of his date.
 Philip Smith accepted the opinion of Karl Julius Sillig (1801—1855) that Pliny's date of Olympiad 87 (c. 428 BC) ought to be referred to this artist rather than to a different Pythagoras, from Rhegium; other writers consider it possible he lived closer to the beginning of the 5th century BC.
 Modern writers consider it certain these two were the same artist, and that this Pythagoras was one of the Samian exiles who moved to Zankle at the beginning of the 5th century BC and came under the power of the tyrant Anaxilas in Rhegium.
 While a Samian by birth, he was a pupil of Clearchus of Rhegium.
Attila ( or ; fl.
 circa 406–453), frequently referred to as Attila the Hun, was the ruler of the Huns from 434 until his death in March 453.
 He was also the leader of a tribal empire consisting of Huns, Ostrogoths, and Alans among others, on the territory of Central and Eastern Europe.
Roger de Clare, 2nd Earl of Hertford, 5th Lord of Clare, 5th lord of Tonbridge, 5th Lord of Cardigan (1116–1173) was a powerful Norman noble during the 12th century England.
 He succeeded to the Earldom of Hertford and Honor of Clare, Tonbridge and Cardigan when his brother Gilbert died without issue.
Hunor and Magor were, according to a famous Hungarian legend, the ancestors of the Huns and the Magyars.
 The legend was first promoted in "Gesta Hunnorum et Hungarorum".
 The legend's aim in providing a common ancestry for the Huns and the Magyars was to suggest historical continuum of the Kingdom of Hungary with the Hun Empire.
 Magyars led by prince Árpád had conquered the area in the 890s.
 The territory had previously been held by Attila the Hun in the 5th century.
 The legend thus tried to prove that the Magyars were simply reclaiming their ancient homeland as descendants of Attila.
 According to Simon of Kéza, Hunor and Magor were the sons of Ménrót, a mythical giant, who he partly identified with Nimrod of the Bible (the great-grandson of Noah).
Zerco or Zercon (410/420 Mauretania - Second half of the 5th century Constantinople ?)
