Islam conquered most of the Middle East and North Africa and then came across the Straights of Gibraltar and conquered Spain, subjugating the people under Islamic rule, giving the European (mostly Christian and Jewish) people the choice of conversion to Islam or perpetual underling status burdened with a tax on non-Muslims (vital funds Muslims used to finance further conquests).
Islamic armies moved north into what is now France (known as Gaul at the time). That was the high-water mark of Islam’s first major invasion of Europe, because it was there they were stopped.
After several large battles, the Islamic hordes were defeated by an army led by Charles Martel, who came to be known as Charles the Hammer. The final and decisive battle occurred on October 11th, 732, one hundred years after the death of Mohammad....

I wonder why government schools never teach this? Democrats are the enemy
"In the sweep of the long history of the Islamic assault on the Christian world, it is sobering to consider how close the latter has come to annihilation on more than one occasion. In the initial offensive during the first decade after Muhammad's demise, Christendom lost its birthplace in the Levant, with the front of the East Roman Empire only being stabilized at the approaches to Asia Minor. Meanwhile, the Arab armies swept west from conquered Egypt, subduing the whole north coast of Africa and crossing into Visigothic Spain in 711. They were finally stopped by the Franks under Karl the Hammer at Poitiers in 732, the centenary of the pseudo-Prophet's death. The conversion of the Turkish tribes to Islam in the 9th century lent jihad renewed impetus; the erosion and final collapse of East Roman power opened the eastern door to Europe in the 14th century, and the Ottomans were turned back only at the gates of Vienna in 1683. The site of the first high water mark at Poitiers and the later one at Vienna are only some 700 miles apart - so narrow has been Christendom's brush with extinction!"
I recall handing out copies of that to coworkers and often wonder how they think now...back then they thought I was completely nuts to think muslims would be interested in a 2nd caliphate. And said so.
