For Westerners, an easy starting approach to all of those places if you aren't familiar with them at all is to learn the boundaries of the old pre-WWI colonial empires, which tend to be associated with easily-remembered West European states, since thinking, for example, "Ah, right, there were those two weird spots the Portuguese used to have in the south of Africa, one on the west coast and one on the east," will tend to give your memory more of a jump start that trying to just cram a bunch of unfamiliar and meaningless words in there with no "story" associated with them.
