They have been named the Northern Crusades- Knightly orders and others thirsty for violence and plunder attacked pagans and Eastern Orthodox Christians, trying to spread Catholic swords throughout medieval Russia.
You have probably heard of the Teutonic Order- - powerful war horses and heavily armoured knights who usually defeated all who stood against them. One of the subgroups of the Teutonic Order was the Livonian Order. Originally they were an independent group called the Livonian Brothers of the Sword, but after a disastrous defeat at Saule, they were decimated and absorbed into the Teutonic Order. The Livonian Order retained all of its original colours and crests.
In the early Thirteenth century the Livonian Order crusaded throughout North Eastern Europe, eventually pushing into what is now Russia, capturing towns and villages.
