Islam started around 600 and the first crusade began in the eleven hundreds.
I am of Mediterranean background, my ancestors fought the muslims for hundreds of years and people from other countries were their victims into the 19th and 20th centuries. Of course the Christian community of the Middle East and North Africa has been gradually ground down to minority status over a thousand years and are still living in subjugation to the muslims.
Weren't the crusades an eventually response to the Muslim encroachment of Europe? I am no historian, but the number I heard was appoximately 100 years after the first Muslim inroads into Europe. Maybe others can enlighten us.
~626 Islam took root by the blade.
