The Italo-Mongol War (1453-1455)

Following The Fall of Constantinople (1452-1453), The Mongols were free to press into The European Heartland of Italy. The Italian State of Milan, long resented among the other Italian states for it's heavy-handed diplomacy and aggressive promotion of Protestantism, Was made a target of The Papal States, who quickly hired the new Mongol Raiders as Mercenaries.

The Mongols converted to Catholicism, and the Pope's cry for a crusade against the Heretic Milanese was taken up by The Orthodox state of Armenia. Several Days of Brutal street-to-street fighting involving stone weaponry in Milan saw the utilization of Boiling-oil pots (lava), which led to many ethical concerns over the nature of combat and its effectiveness.

The War ended with a Milanese acceptance of Papal Overlordship in 1454, effectively ending Inter-Italian conflicts. However, the Mongols were never paid by the Papacy for their sacrifices, and so out of Anger converted to Orthodoxy under the Patriarch of Theodoro. The Mongols continued to Raid the Italian Peninsula for more than a year.
