I just finished reading "Sword and Scimitar: Fourteen Centuries of War between Islam and the West" by Raymond Ibrahim, and it's a devastating account, and an eye popping book, of Islam's spread through Christian lands. 85% of what used to be Christian was conquered by jihad, all of north Africa, all Middle East, all Anatolia, and all the way to Vienna and Spain. Millions died, raped, enslaved, and forcefully converted. White women were particular targets. The overarching theme is that followers of Islam felt it was their holy duty of jihad to wage the war on infidels, no matter what the method and devastation. https://www.amazon.com/dp/0306825554/ref=cm_sw_r_sms_apa_i_F...
