Islam was founded by Muhammad who received a Christian upbringing. His first wife was also Christian.
When the Umayyads introduced Islam to the Levant, they were greeted in Damascus as true Christians, albeit of a new rite suitable for the Bedouins. It was only with time that Islam turned against the Christians, at first by imposing a special tax since they did not pay the Muslim zakat, then by demanding a heavier tax, until one day Daesh came along and expelled them in droves.
