Uldin

Uldin, also spelled Huldin (died before 412), was one of the primary Hunnic rulers mentioned by name.

The name is recorded as Ουλδης (Ouldes) by Sozomen, Uldin by Orosius, and Huldin by Marcellinus Comes. As the Latin variants show, it ended on -n, not Greek suffix -s. The root of the etymon is the verb öl-, which survived in Mongolian olje, ol-jei (auspice, happiness, good luck). The middle suffix jei is originally *di + ge, thus *öl-jige > öl-dige. In place of Mongolian ge, Hunnic has the suffix n. The reconstructed form is *öl-di-n (auspicious, happy, lucky, fortunate).

In 400, Uldin ruled in Muntenia, present-day Romania East of Olt River. The extension of his realm to the North and East is unknown, but to the West probably reached the banks of Danube where Huns were camped since 378-380. When Gainas, former magister militum praesentalis, with his Gothic followers fled across the borders to "his native land", Uldin "did not think it safe to allow a barbarian with an army of his own to take up dwellings across the Danube", and attacked him. Uldin was victorius, killed Gainas and sent his head to the Emperor in Constantinople.

Late in the fall of 404 and in 405, according to Sozomen:

"About this time the dissensions by which the church was agitated were accompanied, as is frequently the case, by disturbances and comotions in the state. The Huns crossed Ister and devastated Thrace. The robbers in Isauria, gathered in great strength, ravaged the towns and villages between Caria and Phoenicia."

In 406, Uldin and Sarus the Goth were called by Roman magister militum Stilicho to help defeat the invasion of Italy by the Goths led by king Radagaisus. Orosius numbered 200,000 Goths. At the Battle of Faesulae (406), Hunnic auxiliaries encircled a significant part of Goths, and Radagaisus tried to escape, but was captured and executed in April 406 AD. It is considered that Goths of Radagaisus fled from the Hunnic lands, who themselves were pushed Westward by other nomadic tribes from the East.
