Title: Theodoric the Great
Content:  Theodoric was born in AD 454 in Pannonia on the banks of the Neusiedler See near Carnuntum, the son of king Theodemir, a Germanic Amali nobleman, and his concubine Ereleuva. This was just a year after the Ostrogoths had thrown off nearly a century of domination by the Huns. His Gothic name, which is reconstructed by linguists as *Þiudareiks, translates into "people-king" or "ruler of the people". In 461, when Theodoric was but seven or eight years of age, he was taken as a hostage in Constantinople to secure the Ostrogoths' compliance with a treaty Theodemir had concluded with the augustus Leo I (ruled 457–474). The treaty secured a payment to Constantinople of

Thietmar names Theodoric as a member of the tribe of the Buzici (de tribu, quae Buzici dicitur) and as a relative on his father's side of Rikdag, Margrave of Meissen (r. 979–985). Several possible fathers have been identified for him, but there is no conclusive evidence for any of them: Depending on who is assumed to be Theodoric's father, it is reasonable to assume a date of birth for Theodoric in the 910s, 920s or 930s. The year of his death has been proposed as 975/6, because it is known that his son Dedo in this year took his own mother hostage in the context of a feud (presumably against his father). Theodoric's wife is named as one Jutta or Judith of Merseburg in early modern historiography.
Title: Theodoric I of Wettin
Content:  Theodoric was born in the early 10th century, to unknown parents. He married Jutta of Magdeburg. They had two sons, Dedo and Frederick. He is mentioned as Dedo's father by bishop Thietmar of Merseburg. Dedo is the first known count of Wettin, and Dedo's son, Theodoric II, Margrave of Lower Lusatia, is the first member of the Wettin dynasty, taken as established by his father. He inherited or acquired Wettin Castle during his career, potentially from his father. Theodoric, as his son Dedo held the rank of Count was presumably Count of Wettin. Little is known about his political career, other he was a supporter of the Duke of Saxony. He died in 975, in a feud against his son.

Title: Theodoric the Great
Content:  Theodoric (or Theoderic) the Great (454 – 30 August 526), also called Theodoric the Amal (Flāvius Theoderīcus; Θευδέριχος), was king of the Ostrogoths (471–526), and ruler of the independent Ostrogothic Kingdom of Italy between 493–526, regent of the Visigoths (511–526), and a patrician of the East Roman Empire. As ruler of the combined Gothic realms, Theodoric controlled an empire stretching from the Atlantic Ocean to the Adriatic Sea. Though Theodoric himself only used the title 'king' (rex), some scholars characterize him as a Western Roman Emperor in all but name, since he ruled large parts of the former Western Roman Empire, had received the former

As a young child of an Ostrogothic nobleman, Theodoric was taken as a hostage to Constantinople, where he spent his formative years and received an East Roman education (paideia). Theodoric returned to Pannonia around 470, and throughout the 470s he campaigned against the Sarmatians and competed for influence among the Goths of the Roman Balkans. The emperor Zeno made him a commander of the Eastern Roman forces in AD 483, and in AD 484 he was named consul. Nevertheless, Theodoric remained in constant hostilities with the

Content:  Theodoric was born in 1260, the third son of Margrave Albert II of Meissen and his wife Margaret of Sicily. After Theodoric's mother fled from the Wartburg in 1270, because her husband had fallen in love with Kunigunde of Eisenberg, Theodoric and his elder brother Frederick were raised by their uncle Margrave Theodoric of Landsberg. After Theodoric and Frederick had come of age, they and their elder brother Henry fought a war against their father, who wanted his son Apitz, from his second marriage with Kunigunde, to inherit the Landgraviate of Thuringia. Theodoric's first territorial possession was the Pleissnerland. After

As the new ruler of Italy, he upheld a Roman legal administration and scholarly culture and promoted a major building program across Italy. In 505 he expanded into the Balkans, and by 511 he had brought the Visigothic Kingdom of Spain under his direct control and established hegemony over the Burgundian and Vandal kingdoms. Theodoric died in 526 and was buried in a grand mausoleum in Ravenna. He lived on as the figure Dietrich von Bern in Germanic heroic legend.

Theodoric thereby was a grandson of the Wettin progenitor Theodoric I. At Christmas 1009, after his father was killed in a fierce struggle with Margrave Werner of the Northern March, Theodoric was vested with the County of Wettin in the Saxon Hassegau (ruling as Theodoric II) by King Henry II of Germany at Pöhlde.

Title: Theodoric
Content:  Rhys surmises that the "historical Teuton" (viz. Theoderic the Great) bore a name of the Gaulish Apollo as adopted into early Germanic religion. The first known bearer of the name was Theodoric I, son of Alaric I, king of the Visigoths (d. 451). The Gothic form of the name would have been Þiudareiks, which was Latinized as Theodericus. The notability of the name is due to Theoderic the Great, son of Theodemir, king of the Ostrogoths (454&ndash;526), who became a legendary figure of the Germanic Heroic Age as Dietrich von Bern. After the end of Late Antiquity, during the 6th to 8th century there were also several kings of the Franks called Theodoric (or Theuderic). Finally, there was an early Anglo-Saxon king of Bernicia called Theodric (also spelled Deoric, Old English Þēodrīc).
