The Russian empire was a multiethnic with the German migrants
Explanation:
Christianity in the middle ages dominated the lives of both peasants and the nobility. Religious institutors including the Church and the monasteries became wealthy and influential given the fact that the state allocated a significant budget for religious activities
I was asked this question during my history class.
In 313 AC, the edict of Milan was published by the Roman Empire during the rule of Ceasar Konstantin the First. The Ceasar allowed christianity as a religion in his empire however the changes took a long time until in 395 AC when christianity became official religion and the only one acceptable in the Roman Empire.
Hope this helps.
