Attila

Attila (406-453) was the King of the Huns who was known as the “Scourge of God” as the Romans felt he was a punishment sent for sinful Christians by God. He twice attacked the Eastern Roman Empire to increase the quantity of tribute paid to him, 441–443 and 447–449, and then attacked the Western Roman Empire 450–452.
In 451 Attila and his fellow Huns were on the march in Gaul. The French withdraw more and more inside France until it seemed Paris would fall. However a Christian woman, Genevieve, promised the Parisians that if they prayed to God and don’t flee, Attila would not come. The “Scourge of God” was defeated at Châlons and was forced to retreat to the Parisians great relief.
Attila himself and his fellow Huns had a fairly superficial Arian Christian faith which at least helped them to maintain high certain standards of Christian morality and gave them a great respect for life and property, especially churches, Christian relics and treasures.
