The Magyars had conquered the Pannonian Basin (present-day Hungary) by the end of the ninth century, and launched a number of plundering raids both westward and southward. The westward raids were stopped only with the Magyar defeat at the Battle of Lechfeld of 955, which led to a new political order in Western Europe centered on the Holy Roman Empire. Around 1000 AD, the Babenberg ruled in the area that is now modern Vienna. In 1014 came the first written mention of what today is Floridsdorf Jedlesee, then called Outcinesse (Sea of Uz).
