History of Europe
In 395 Theodosius I, who had made Christianity the official religion of the Roman Empire, would be the last emperor to preside over a united Roman Empire. The empire was split into two halves: the Western Roman Empire centred in Ravenna, and the Eastern Roman Empire (later to be referred to as the Byzantine Empire) centred in Constantinople. The Roman Empire was repeatedly attacked by Hunnic, Germanic, Slavic and other “barbarian” tribes (see: Migration Period), and in 476 finally the Western part fell to the Heruli chieftain Odoacer.
House of Habsburg
After the death of his father in 1493, Maximilian was proclaimed the new King of the Romans, receiving the name Maximilian I. Maximilian was initially unable to travel to Rome to receive the Imperial title from the Pope, due to opposition from Venice and from the French who were occupying Milan, as well a refusal from the Pope due to enemy forces being present on his territory. In 1508, Maximilian proclaimed himself as the "chosen Emperor," and this was also recognized by the Pope due to changes in political alliances. This had a historical consequence in that, in the future, the Roman King would also automatically become Emperor, without needing the Pope's consent. In 1530, Emperor Charles V became the last person to be crowned as the Emperor by the Pope.
