 Constantine considered Constantinople as his capital and permanent residence . He lived there for a good portion of his later life . He rebuilt Trajan 's bridge across the Danube , in hopes of reconquering Dacia , a province that had been abandoned under Aurelian . In the late winter of 332 , Constantine campaigned with the Sarmatians against the Goths . The weather and lack of food cost the Goths dearly : reportedly , nearly one hundred thousand died before they submitted to Rome . In 334 , after Sarmatian commoners had overthrown their leaders , Constantine led a campaign against the tribe . He won a victory in the war and extended his control over the region , as remains of camps and fortifications in the region indicate . Constantine resettled some Sarmatian exiles as farmers in Illyrian and Roman districts , and conscripted the rest into the army . Constantine took the title <unk> maximus in 336 .
