Constantine IV vs Theodoric the Great

Constantine IV successfully defended Constantinople against a massive Arab siege that lasted from 674 to 678. The Byzantine victory, aided by the use of Greek fire, forced the Umayyad Caliphate to sue for peace and pay tribute.

Constantine IV continued the reorganization of the Byzantine military into thematic provinces. This system, which combined civil and military authority, proved effective in defending the empire against external threats.

Constantine IV convened the Third Council of Constantinople, which condemned Monothelitism as a heresy. The council restored religious unity between Constantinople and Rome, ending a long-standing theological dispute.

Theodoric the Great led the Ostrogoths in conquering Italy from Odoacer. He defeated Odoacer in several battles and eventually besieged Ravenna. Theodoric tricked Odoacer into a truce and then murdered him, establishing the Ostrogothic Kingdom of Italy.

Theodoric established the Ostrogothic Kingdom in Italy with its capital at Ravenna. He maintained Roman administrative structures and laws while ruling as a Gothic king. His reign brought stability and prosperity to Italy, blending Roman and Gothic cultures.

Theodoric promoted coexistence between Romans and Goths, allowing Romans to keep their laws and institutions. He appointed Romans to high offices and supported the Roman Senate. This policy maintained stability and preserved Roman culture in Italy.

Theodoric ordered the execution of the philosopher Boethius on charges of treason. Boethius had been a high-ranking official and was suspected of conspiring with the Byzantine Empire. This event tarnished Theodoric's reputation as a just ruler and highlighted tensions between Romans and Goths.
