Kuwait was not permitted any role in the outcome of the Uqair agreement when the Saudis and British decided Kuwait's modern boundaries. Kuwait lost more than two thirds of its territory as a result of the agreement, as well as its second largest town, the port of Manifa[3]. The loss of territory made anti-British sentiment grow in Kuwait.
