What Is the Shortest Lived Country in History?

Across the world there are many different countries, but for the exact total amount it depends on how you look at it. According to the United Nations there are currently 195 countries. But of course there are many more that have limited recognition by other nations, like Abkhazia and the Sahrawi Arab Democratic Republic, and there also a few that no one recognizes, like Somaliland and Transnistria.
