The first target of the Christianization crusades of the Teutonic Knights were the Prussians. A nation valiant and fierce in paganism. The first Piasts (Polish kings first dynasty) wrangled over that tribes and finally, in the times when Poland was divided into small principalities, therefore weak, one of Piasts’ princesses asked for support the armed monks in white surcoatswith a black cross. Teutonic knights conquered, Christianized and tamed the brave Prussian tribes… but for sure?
