“During this time Christians fought holy wars against Muslims in Spain.”  p.669 My World History (Early Ages)

Never in this textbook is the term “holy war ” used to describe wars by Muslims against Christians. But in fact in the Quran the word Jihad is the contextual meaning of the term “holy war” against all non-Muslims.  In other textbooks, when the word Jihad is used, it is referred to as an internal struggle with moral issues.
