Dalmatia was a Roman province. Its name is derived from the name of an Illyrian tribe called the Dalmatae, which lived in the central area of the eastern coast of the Adriatic Sea. It encompassed the northern part of present-day Albania, much of Croatia, Bosnia and Herzegovina, Montenegro, Kosovo and Serbia, thus covering an area significantly larger than the current Croatian region of Dalmatia. Originally this region was called Illyria (in Greek) or Illyricum (in Latin).
The province of Illyricum was dissolved and replaced by two separate provinces: Dalmatia and Pannonia.
CONCLUSION
I was born in Dalmatia. I was the first Christian Roman Emperor.


thanks for the history lesson Emperor Constantine.
In Hoc Signo Vinces
(Chorus)
o Constantine, temporum novorum imperator,
Sub tuo regno Roma iterum prospere!
Per proelia stella tua fulsit;
Romae Imperatore in aetemo sculpta.
In Hoc Signo Vinces
(Vers. 2.)
Apud Milvium crux fulgebat in caelo;
Signum victoriae, signum providum.
Sub signo Christi legiones cedunt;
Ad tempora pacis divina societas.
(Chorus)
o Constantine, temporum novorum imperator,
Sub tuo regno mundus requiem invenit.
Per proelia stella tua fulsit;
Romae Imperatore in aetemo sculpta.
In Hoc Signo Vinces
(Pontus)
renascitur byzantii sub lumine tuo;
Constantinopoli gemma et lux.
Imperium divisum scientia vestra unitum;
Christianitas gliscit, sub tua aegida, spei plenae.
