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!
