The United Arab Emirates is a federal constitutional monarchy made up from a federation of seven hereditary tribal monarchy-styled political system called Sheikhdoms. It is governed by a Federal Supreme Council made up of the ruling Sheikhs of Abu Dhabi, Ajman, Fujairah, Sharjah, Dubai, Ras al-Khaimah and Umm al-Quwain. All responsibilities not granted to the national government are reserved to the individual emirate. A percentage of revenues from each emirate is allocated to the UAE's central budget. The United Arab Emirates uses the title Sheikh instead of Emir to refer to the rulers of individual emirates. The title is used due to the sheikhdom styled governing system in adherence to the culture of tribes of Arabia, where Sheikh means leader, elder, or the tribal chief of the clan who partakes in shared decision making with his followers.
