Why was Christianity successful in officially converting Rome after Rome's long continuos history of polytheism?

Forgive me if I misunderstand any concepts, I'm still new to this part of history. As the title states, I'm curious why Christianity finally converted Rome when Rome had been officially Roman polytheistic throughout its history, even during times of strong exposure to many different religions.

So, the question is why the Roman Empire converted to christianity, correct?

Just double checking.
