The First Council of Nicaea was a council of Christian religious bishops convened in the Bithynian city of Nicaea (currently called Iznik, Bursa province, Turkey) by the Roman Emperor Constantine I in AD 325.
It resulted in the first uniform religious Christian doctrine, called the Nicene Creed.
In 313, the struggles of the religious Early Church of Rome were lessened by the legalisation of Christianity by the Emperor Constantine I.
In 380, under Emperor Theodosius I, Christianity became the state religion of the Roman Empire by the decree of the Emperor.
The First Council of Constantinople was a council of Christian religious bishops convened in Constantinople in AD 381 by the Roman Emperor Theodosius I confirmed the religious Nicene Creed. The Christianity were born then, 300- 400 AD.

Constantine wanted fame and he got it.
