Riyadh

History
In 1947 a border dispute between Abu Dhabi and Dubai grew into a full scale war between the two. The British were unable delineate a border that both would agree on, leading to Dubai invading Abu Dhabi. The war dragged on for another 6 months before the British intervened. The United Kingdom proposed the formation of a new Sheikhdom between the two emirates, to act as a buffer zone.
