Brasilia only became the capital of Brazil in 1960.
Also, Léopoldville is just the former name of Kinshasa rather than a different place. If that is the criterium, a couple of other things need to be changed...
I agree for Brasilia too. And for the change of name it's not very clear yeah because if you consider it a change of capital then you need to add a lot more capitals, like for Astana you should go through all the changes of names since the sixties
There are a few mistakes or choices here that are debatable, but overall it's a fun idea. I had no idea about Kolonia, FS Micronesia until today. It looks like Palikir became the capital in 1989, not 1999 like it states here. Also, interestingly, Palikir is a purpose built capital, and doesn't have much going on aside from government.
