I want to know the answer to the following question:
What group was defeated at the Battle of Lechfeld?
All the background I'm provided with is that "The breakup of the Abbasid dynasty meant that the Islamic world fragmented into smaller political states, some of which began expanding into Italy and Sicily, as well as over the Pyrenees into the southern parts of the Frankish kingdoms.". Is that enough to answer the question?
Answer: no
