Hilton Young Commission: The Hilton Young Commission was a Commission of Inquiry appointed in 1926 to look into the possible closer union of the British territories in East and Central Africa.  These territories were individually economically underdeveloped, and it was suggested that some form of association would result both in cost savings and their more rapid development.  The Commission recommended an administrative union of the East African mainland territories, possibly to be joined later by the Central African ones.  It also proposed that the legislatures of each territory should continue and saw any form of self-government as being a long-term aspiration.  It did however reject the possibility of the European minorities in Kenya or Northern Rhodesia establishing political control in those territories, and rejected the claim of Kenyan Asians for the same voting rights as Europeans.  Although the Commission's recommendations on an administrative union were not followed immediately, closer ties in East Africa were established in the 1940s.  However, in Central Africa, its report had the effect of encouraging European setters to seek closer association with Southern Rhodesia, in what became in 1953 the Federation of Rhodesia and Nyasaland.
