Director (colonial)

The title director has been used in colonial administrations not only as a bureaucratic rank and for the members of a board of directors, but also specifically, as in this article, for the head of the colonial administration of a territory under indirect rule by a chartered company, functionally equivalent to a governor.
Elsewhere, the same function went by the - in principle higher - title director-general, as in Demerara-Essequibo.

British colonies

From 5 June 1885 the Niger Districts Protectorate was administered by Sir George Goldie, until it became on, 10 July 1886, the Niger River Delta Protectorate.
The short-lived English trading post at Hirado had a single director: Richard Cocks
