The roadway to the Roman empire with a new and even more powerful ruler, Attila the Hun after he took power in AD 445 was easy as they defeated everyone in their path.
Attila the Hun was the most powerful ruler of the Huns and under his rule, the Huns defeated Northern Italy, and took over Central Europe around HUNgary while the Pope convinced them to not demolish Rome
Attila died in his sleep on the night of his last wedding due to a nasal hemorrhage, but some folks disagree, saying he was poisoned.
