#6 Attila the Hun
He was a warrior and a leader of the Huns from 434 to 453. During his two decades of ruling the Hunnic Empire Attila was known for invading and conquering numerous territories, leaving death in each village he went through. Attila crossed the Danube twice and robbed the Balkans but never made it to Constantinople. He gave a whole lot of trouble to Romans, plundering the northern provinces of Italy, which earned him a nickname ‘Scourge of God’. Although he planned to attack and conquer Rome, Attila was killed in 453 on his wedding night.
