While various groups, including the Franks, were resisting Muslim advances, Germany itself was not under Muslim control by 750 CE. The region primarily remained under local Germanic tribes and was not significantly impacted by Muslim rule during this period.

During this time, England was experiencing its own internal conflicts and was not invaded by Muslim forces. The primary influences in England were from the Anglo-Saxon kingdoms, and it remained largely outside the reach of Muslim rule until much later.

The Balkans were not under Muslim control by 750 CE either, as the region was still largely influenced by the Byzantine Empire and Slavic tribes. While Muslim incursions would later occur, they did not establish control in the Balkans at this early point in history.

Italy was not fully ruled by Muslims by 750 CE. Although there were some incursions and Muslim raiding parties, the significant control of Italian territories by Islamic powers did not occur until later periods, particularly with the rise of the Ottoman Empire centuries after this date.
