No, a khalif is a religious and worldly leader of a community.
According to Wiki: "A caliphate (Arabic: خِلافة khilāfa) is a form of Islamic government led by a caliph (Arabic: خَليفة khalīfah pronunciation (help·info))—a person who claims to be a political and religious successor to the prophet Muhammad and a leader of the entire Muslim community."
I know people often mock wikipedia, but they're correct in this. ;)
I never said that the killings of ISIS are purely religious in nature. I'm saying that religion and politics go hand in hand in the Middle East.
The Caliph was just a religious leader for centuries due to the political stuff becoming the Sultan's business.
