In 1850, a person looking for interesting places to visit could have considered sovereign states like the Kingdom of Ankole, the Austrian Empire, the Kingdom of Joseon, the Kingdom of Janjero, the Ryukyu Kingdom, the Principality of Waldeck and Pyrmontor, the Khanate of Kokand, and the Sulu Sultanate.
If you have never heard of these places and can’t find them on a map, that's understandable. That’s because by 1930, none of these states existed as they were either annexed, conquered, renamed, dissolved or colonised.
