Theodoric I (;Moritz Schönfeld, Wörterbuch der altgermanischen Personen- und Völkernamen (1911), p. 234 ;  390According to French historian Claude Barret his estimated birth is circa 390.
or 393 – 20 or 24 June 451According to French historian Claude Barret, he died on June 24, 451 at the Battle of the Catalaunian Plains [Also called the Battle of Châlons or the Battle of Maurica]) was the King of the Visigoths from 418 to 451.
Theodoric is famous for his part in defeating Attila (the Hun) at the Battle of the Catalaunian Plains in 451, where he was killed.Jordanes, De Origine Actibusque Getarum, 40.209.
Early career
In 418 he succeeded King Wallia.
The Romans had ordered King Wallia to move his people from Iberia to Gaul.
As king, Theodoric completed the settlements of the Visigoths in Gallia Aquitania II, Novempopulana and Gallia Narbonensis, and then used the declining power of the Roman Empire to extend his territory to the south.
After the death of Emperor Honorius and the usurpation of Joannes in 423 internal power struggles broke out in the Roman Empire.
Theodoric used this situation and tried to capture the important road junction Arelate, but the Magister militum Aëtius, who was assisted by the Huns, was able to save the city.Prosper, Epitoma chronicon 1290, in: MGH Auctores antiquissimi (AA) 9, p. 471; Chronica Gallica of 452, 102, in: MGH AA 9, p. 658; Sidonius Apollinaris, letters 7.
12. 3
The Visigoths concluded a treaty and were given Gallic noblemen as hostages.
The later Emperor Avitus visited Theodoric, lived at his court and taught his sons.Sidonius Apollinaris, carmen 7.

Expansion to the Mediterranean
Because the Romans had to fight against the Franks, who plundered Cologne and Trier in 435, and because of other events Theodoric saw the chance to conquer Narbo Martius (in 436) to obtain access to the Mediterranean Sea and the roads to the Pyrenees.
But Litorius, with the aid of the Huns, prevented the capture of the city and drove the Visigoths back to their capital Tolosa.Prosper, Epitoma chronicon 1324 and 1326, in: MGH AA 9, p. 475; Hydatius, chronicle 107 und 110, in: MGH AA 11, p. 22-23; Merobaudes, panegyric, fragment II A 23, in: Vollmer, MGH AA 14, p. 9; Sidonius Apollinaris, carmen 7.
246sqq.; 7.
475sqq.
Theodoric's offer of peace was refused, but the king won the decisive battle at Tolosa, and Litorius soon died in Gothic imprisonment from the injuries which he had received in this battle.Prosper, Epitoma chronicon 1335, in: MGH AA 9, p. 476; Hydatius, chronicle 116, in: MGH AA 11, p. 23; Salvian, de gubernatione dei 7.
9. 39sqq.
Avitus went – according to the orders of Aëtius – to Tolosa and offered a peace treaty which Theodoric accepted.Prosper, Epitoma chronicon 1338, in: MGH AA 9, p. 477; Hydatius, chronicle 117, in: MGH AA 11, p. 23; Sidonius Apollinaris, carmen 7.
295sqq.
Perhaps the Romans recognized at that time the sovereignty of the Visigoth state.
Conflict with Vandals
A daughter of Theodoric had been married to Huneric, a son of the Vandal ruler Genseric (in 429?), but Huneric later had ambitions to wed Eudocia, a daughter of the Emperor Valentinian III.
He therefore accused the daughter of Theodoric of planning to kill him, and in 444 had her mutilated - her ears and nose cut off"The Fall of the West" by Adrian Goldsworthy, W&N (2009),  (page 330) - and sent back to her father,Jordanes, Getica 36, 184 which earned the enmity of the Vandals.
In 444, an enemy of Aëtius, the former magister militum Sebastianus, came to Tolosa.Hydatius, chronicle 129, in: MGH AA 11, p. 24 (dated into the year 444); Prosper, Epitoma chronicon 1342, in: MGH AA 9, p. 478 (wrongly dated into the year 440) This could have strained relations with Aëtius, but Theodoric soon sent his unwelcome guest away, after which the latter captured Barcelona and then was executed on Geiseric's orders in 450.
Theodoric was also an enemy of the Suevic king Rechila in Iberia, because Visigoth troops assisted the imperial commander Vitus in his campaign against the Suevi in 446.Hydatius, chronicle 134, in: MGH AA 11, p. 24 But the ability of this people to conduct a strong defence and the better relations between Geiseric and the Roman Empire led Theodoric to change his foreign policy.
He therefore, in February 449, married one of his daughters to the new Suevic king Rechiar, who visited his father-in-law at Tolosa in July 449.Hydatius, chronicle 140 and 142, in: MGH AA 11, p. 25; Jordanes, Getica 44.
229 and 231 On his return – according to the author Isidore of Seville - Rechiar, with the assistance of Visigoth troops,Isidore, Historia Gothorum, Vandalorum et Suevorum 87, in: MGH AA 11, p. 301 devastated the area surrounding the city of Caesaraugusta and managed by guile to take Ilerda.
Some recent scholars doubt that Theodoric issued legislation, as it was assumed in earlier times.G. Kampers, RGA, vol. 30, p. 420 Alliance against the Huns

Theodoric joined this coalition because he recognized the danger of the Huns to his own realm.
With his whole army and his sons, Thorismund and Theodoric, he joined Aëtius.
The Visigoth and Roman troops then saved the civitas Aurelianorum and forced Attila to withdraw (June 451).Sidonius Apollinaris, carmen 7, 346sqq.; letters 7.

115-116 Battle of Châlons
Then Aëtius and Theodoric followed the Huns and fought against them at the Battle of Châlons near Troyes in about June 451.
Most Visigoths fought at the right wing under the command of Theodoric but a smaller force fought at the left under the command of Thorismund.Jordanes, Getica 38.
197 and 201
Theodoric's forces contributed decisively to the victory of the Romans, but he himself was killed during the battle.
Jordanes records two different accounts of his death: one was that Theodoric was thrown from his horse and trampled to death; the second was that Theodoric was slain by the spear of the Ostrogoth Andag, who was the father of Jordanes's patron Gunthigis.
The body of Theodoric wasn't found until the next day.
According to Gothic tradition he was mourned and buried by his warriors on the battlefield.Jordanes, Getica 40.
209 and 41.
214; Hydatius, chronicle 150, in: MGH AA 11, p. 26 Immediately Thorismund was elected as successor of his father.
Other sons of Theodoric were Theodoric II, Frederic, Euric I, Retimer and Himnerith.Jordanes, Getica 36.
190 Legacy
For his sacrifice and subsequent victory over Attila at the Battle of the Catalaunian Plains, Theodoric became a revered figure in Western historiography, and served as an inspiration for J. R. R. Tolkien in his creation of king Théoden of Rohan in The Lord of the Rings and The Battle of the Pelennor Fields.
