The Cooperation Council for the Arab States of the Gulf, originally (and still colloquially) known as the Gulf Cooperation Council is a regional, intergovernmental political and economic union that consists of:
- Saudi Arabia
- United Arab Emirates
The council main headquarter is in the city of Riyadh in Saudi Arabia. The Charter of the GCC was signed on 25 May 1981, formally establishing the institution. All current member states are monarchies, including three constitutional monarchies (Qatar, Kuwait, and Bahrain), two absolute monarchies (Saudi Arabia and Oman), and one federal monarchy (the United Arab Emirates, which is composed of seven member states, each of which is an absolute monarchy with its own emir). There have been discussions regarding the future membership of Jordan, Morocco, and Yemen.
