Official Country Names (minus "Republic of [common name]")
Like 80 of them were just "Republic of Albania", "Republic of Angola", "Republic of Armenia", etc.
Here are the interesting ones: Kingdoms, Principalities, People's Democratic Republics, and - shockingly rare - official names that are just the same things as the common names.
Be careful. Here and there, I decided to keep a "Republic of..." if I thought there was good reason.
