Couple of centuries after Christ, Constantine was very popular name. Especially among soldiers in Roman and Bysantine empires along with Greeks during their Macedonian age. Within latin Cōnstantīnus and greek Κωνσταντῖνος (Kōnstantînos) name literally means the one who's constant and steadfast especially within military properties related to strength and stamina. In those times the land of my current location was called "Moesia Superior" with the city of Naissus in the role of its main trade center and biggest military outpost for Roman army. Today's name of the city is "Niš", the largest city of southern Serbia and also the city where I was born and where I live ever since. Serbian usage of the name is "Konstantin" and even though it is not related to military anymore, the name is fairly popular nowadays among young Serbians. It was third on my list when my son was born simply because I really like names with strong inner "adjectivity"
