Islamics launched their Jihad in 630 A.D.
The western Crusades started in 1095 A.D. in a belated response to four hundred years of relentless Islamist aggression.
The Crusades were a defensive action against the forcible expansion of Islam into territories that had been part of Christendom for centuries.
The violent expansion of the new faith was started in the year 630 A.D. when Muhammad invaded and conquered Mecca.
Later on,Islamist armies invaded Syria, Iraq, Jerusalem, Iran, Egypt, Africa, India, Spain, Italy, France, etc.
The Islamic Jihads continued long after the western Crusades. They have killed about 270 million people: 120 million Africans, 60 million Christians, 80 million Hindus and 10 million Buddhists.
