Thus 1897 saw the definition of the British Somali sphere in relation to Ethiopia. But it was not until 1934, when an Anglo-Ethiopian boundary commission attempted to demarcate the boundary, that British-protected Somali became aware of what had happened, and expressed their sense of outrage in disturbances which cost one of the commissioners his life. This long period of ignorance, far from indicating acquiescence, was facilitated by the many years which elapsed before Ethiopia established any semblance of effective administrative control in the Haud and Ogaden.
