USSR (or CCCP in Cyrillic)

Sorry, already guessed as Soviet Union

Ottoman Empire! #9 - Bulgaria, Iraq, Saudi Arabia, Turkey, and a tad partial for the Ottoman Empire splitting North and South Yemen which later united.

For last two:

#8 - Former Eastern European Country, Split into 5 smaller countries
#10 - Former North American Country, Split into 4 smaller countries

Czechoslovakia?

North Lichtenstein

Austria-Hungary?

I know the answer to the American one, but can't say because I only know it because I looked it up and I wouldn't have ever guessed it in a million years. I think the Eastern European has already been guessed, but just for chuckles I'm going to guess Bohemia.

The country which was last ruled by Austria-Hungary was... Hungary
Czechoslovakia got the two that you'd expect.

The final two correct answers, were:

Yugoslavia, which split into Bosnia and Herzegovina, Croatia, North Macedonia, Slovenia, and Serbia (Montenegro later split from Serbia)

aaaaaaand

The Federal Republic of Central America, which was a brief union of Costa Rica, El Salvador, Guatamala, Honduras, and Nicaragua (hey, what's the deal, Panama?). One thing I missed was that the union was revived twice, once in the late 1890s without Costa Rica and Guatamala, and again from 1921 to 1922 without Nicaragua. All unions seemed to fail when those opposing the union immediately take to arms. But there is a lasting nostalgia for the brief union (all the countries involved have flags that are based on the FRCA flag, they also united militarily to take on the invasion of filibuster ).

Congrats on eeking out a 1pt victory, Mike! Thanks everyone for playing
