Did you mean the "first" Muslim crusades, almost 400 years before the first Christian crusades?
-------------------
In 711 AD, the commander of the Muslim crusaders, called "Moors," was Ṭāriq ibn Ziyad.
Ṭāriq landed, with his 80,000-man Umayyad army, at a place where there was a large mount, for which the Arabic word is "jabal."
The place took his name "Jabal Ṭāriq," or as it was later pronounced "Gibraltar."
Moorish cavalry, wielding curved scimitar swords, "went through all places like a desolating storm."
The Mozarabic Chronicle, 754 AD, recorded that thousands of churches were burned and: "God alone knows the number of the slain."
I should have put the /s tag to be more clear.
The “aggression” was 99% one way.
In 732 Charles Martel (The Hammer) stopped the Muslim advance into Europe at the Battle of Tours. The link below lists several articles about the battle. Also dozens of clickable pictures leading to other important and historical battles for the battle buffs here.
If you want some idea of how many Old World peoples discovered America, find Gloria Farley’s book “They All Discovered America.” We were discovered over and over for millenia, but Columbus’ expedition was the first one that was maintained. Portuguese fishermen had been visiting The Grand Banks of Newfoundland before 1492. The Vikings probably brought smallpox to the US/Canadian northeast, which is why when the Pilgrams landed at Cape Cod, they were not met by a large force of hostile braves. I was at Epcot Center in Disney/Orlando decades ago and and saw a “Mayan” ceramic that I would swear had been painted by a Japanese. They might have traded with the American west coast. As DNA results accumulate, we will learn more and more interesting things about mobile humanity.
