"A caliphate is an Islamic state. It's led by a caliph, who is a political and religious leader who is a successor (caliph) to the Islamic prophet Muhammad. His power and authority is absolute."

This article claims that Islam is not a race or political. And that it was European racists and Islamophobes who introduced this concept to the Muslim world.

If that were true, how could several historical Islamic Empires have conquered and controlled so much territory throughout history? A Caliphate is a religious based government that gives total control to a person from said religion. The Islamic language and Koran have words for non-Muslim people and instructions on how to deal with non-Muslim people. These include not paying taxes, being able to lie to a non-Muslim without guilt or penalty, killing non-Muslims who refuse to convert, killing Muslims who don't live by the rules of the faith or who attempt to leave the faith
