For everyone who is wondering: "de facto" means "technically it isn't, but actually it is" i.e. when there is a successful coup in a country the old president may still be the official president but the new president, while not technically the president is the "de facto" president. He's the one making the decisions that the president should make.
(I say as someone beats me)
Man, I was sooo close to nearly getting a really high percentage of most of these.
