In God's Battalions, award-winning author Rodney Stark takes on the long-held view that the Crusades were the first round of European colonialism, conducted for land, loot, and converts by barbarian Christians who victimized the cultivated Muslims. To the contrary, Stark argues that the Crusades were the first military response to unwarranted Muslim terrorist aggression.
