2 Long lasting effects from Constantine in Europe?

- The Edict of Milan (313 AD): This edict, issued by Constantine and Licinius, granted freedom of worship to all religions in the Roman Empire, including Christianity. This was a major turning point in the history of Christianity, as it marked the end of official persecution of Christians in the empire.

- The Donation of Constantine: This document, which is now considered to be a forgery, purported to grant the Western Roman Empire to the Pope. This donation had a profound impact on the development of the papacy, as it gave the Pope temporal power over a large part of Europe.
