Constantine considered Constantinople his capital and permanent residence. He lived there for a good portion of his later life. In 328, construction was completed on [[Constantine's Bridge (Danube)|Constantine's Bridge]] at ''[[Sucidava]]'', (today [[Corabia|Celei]] in [[Romania]])<ref>Madgearu, Alexandru

In the late winter of 332, Constantine campaigned with the [[Sarmatians]] against the [[Goths]]. The weather and lack of food reportedly cost the Goths dearly 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.<ref>Barnes, ''Constantine and Eusebius'', 250.</ref> Constantine resettled some Sarmatian exiles as farmers in Illyrian and Roman districts and conscripted the rest into the army. Constantine reconquered the South of Dacia and the new frontier in Dacia was along the wall and ditch called [[Brazda lui Novac]] line supported by new ''[[castra]]''.<ref>Madgearu, Alexandru(2008).

In the last years of his life, Constantine made plans for a campaign against [[Sasanian Empire|Persia]]. In a letter written to the king of Persia, [[Shapur II|Shapur]], Constantine had asserted his patronage over Persia's Christian subjects and urged Shapur to treat them well.<ref>Eusebius, ''VC'' 4.9ff, cited in Barnes, ''Constantine and Eusebius'', 259.</ref> The letter is undatable. In response to border raids, Constantine sent Constantius to guard the eastern frontier in 335. In 336, Prince Narseh invaded Armenia (a Christian kingdom since 301) and installed a Persian client on the throne. Constantine then resolved to campaign against Persia. He treated the war as a Christian crusade, calling for bishops to accompany the army and commissioning a tent in the shape of a church to follow him everywhere. Constantine planned to be baptised in the [[Jordan River]] before crossing into Persia. Persian diplomats came to Constantinople over the winter of 336–337, seeking peace, but Constantine turned them away. The campaign was called off, however, when Constantine became sick in the spring of 337.<ref>Barnes, ''Constantine and Eusebius'', 258–59. See also: Fowden, "Last Days", 146–48, and Wiemer, 515.</ref>
