2565: Guinea-Bissau Dec 21, 2021

There are a number of places named for 'Guinea', a historical region of Africa. Among those, Guinea Bissau is notable because 'Bissau' is not an adjective in the same way as found with 'Equatorial Guinea'. Rather, Bissau is the capital and was named from this after formerly being 'Portuguese Guinea' because the nonspecific 'Guinea' was already taken, having itself once been 'French Guinea'.
