During the Muslim conquests and the reign of the Caliphates, the people that were conquered were treated in terrible manner in general. The Caliphs wanted their religion spread among all the people they ruled over, which led to forcing the people to accept the Islam against their will, the ones that opposed were usually murdered and enslaved, there was an Arabic assimilation going on, and multiple systematic genocides.
