Europe didn’t have a common religion after the Reformation (at least not in the sense people who lived there at the time would recognise).
In fact it was wars with a strong religious element between Protestant and catholic factions that tore Europe apart for centuries afterwards
Europe didn't have a common religion before the reformation as well. There were literal crusades inside Europe including against other christians: https://en.wikipedia.org/wiki/Northern_Crusades
