The term "banana republic" can be traced back to a collection of short stories by
O.Henry a called "
Cabbages and Kings." In that book, he described his observations based on the time he lived in Honduras when he was on the run for bank embezzlement. The portrait O. Henry drew was not a flattering one.
The bare-bones definition of a "banana republic" is a politically-unstable nation with an economy dependent on a chief export controlled by a single corporation, usually in foreign hands.
But there's more to it than that.
