As a Finn I must comment the question about "northern country annexed by Russia": Finland didn't actually exist as a country that time. Technically Russia annexed an eastern county of Sweden, normally referred as "Eastland". The idea of a nation or country named Finland was only created sometimes after 1850.
I'm pretty sure Napoleon III was also an Emperor of France. While the question accepts both people (They have the same name anyway), you should probably acknowledge them both in the question.
I typed Taiwan and Formosa three times each before I decided Taiwan must not have become a Dutch colony at this time. Turns out the Dutch only had a limited presence in Taiwan and abandoned the island entirely in 1668.
Still insane though. From Homo Sapiens to 1809 to reach one billion and from 1810 to 2022 to reach 8 billion. And we've sped up to a billion every 11 years since 1999.
Ceres is not an asteroid, it was classified as a dwarf planet in 2006. It is a part the asteroid belt between Mars and Jupiter, but not an asteroid itself!
Great quiz, but (as Saintscat mentioned), I was surprised to see that the US rooted its piracy on the Barbary Coast (our -> out was probably the intended meaning).
But the idea of American privateers in the Mediterranean is funny enough that maybe the typo almost deserves to remain...
As previously mentioned by Tysia, Ceres is not considered an asteroid anymore, but a dwarf planet. So it was reclassified from planet to asteroid, and then back to (dwarf) planet.
> Ceres is a dwarf planet, but there is some confusion about whether it is also an asteroid. A NASA webpage states that Vesta, the belt's second-largest object, is the largest asteroid.[46] The IAU has been equivocal on the subject,[47][48] though its Minor Planet Center, the organisation charged with cataloguing such objects, notes that dwarf planets may have dual designations,[49] and the joint IAU/USGS/NASA Gazetteer categorises Ceres as both asteroid and a dwarf planet.[50]
