Whatever Happened to Tanganyika?

A quick read, with 1-4 pages on each placename - now defunct.
Old favourites like Ceylon, Zaire, Burma and the New Hebrides. Places more marginal in recognition - Tanganyika, Batavia and Spanish Sahara. And places I haven't hard of - Chagos Islands, Fernando Po,Cathures, Neutral Moresnet and Pleasant Island!
