Gulf of Tadjoura
From 1862 until 1894, the land to the north of the Gulf of Tadjoura was called "Obock" and was ruled by Somali and Afar Sultans, local authorities with whom France signed various treaties between 1883 and 1887 to first gain a foothold in the region. The exchange of Franco-British diplomatic notes of 2 and 9 February 1888 fixed the territorial limit between the colonies of the two countries; leaving explicitly under French authority the southern coasts of the Gulf of Tadjoura, including a peninsula composed of insubmersible plateaux, Ras Djibouti as a highly strategic location, a future bridgehead for French designs in the rest of Africa and Asia. It is then that this point begins to be used as departure for caravans towards Harar.
