If you don't want to have to listen to a lot of history, you can choose another setting if you'd like.
Anyway, here's the
podcast. The stuff about the Latin American revolutions is series 5, and should start on that page. The first few episodes are mostly setup, by the way, so I guess I'll sum up some stuff if you'd prefer the TD;LR version.
Portugal and Spain begin colonizing the Americas, and things go surprisingly well for most of it (Aside from the usual colonial racism) until Napoleon rolls in and deposes the king. Immediately, the latin american elite goes wild, setting up all manner of improvised senate, though nobody's actually started declaring independence yet. This changes (In Venezuela) when the American-born elite start opposing the Spain-born elite, and eventually several politically minded people (Including Simon Bolivar, the Liberator, and Francisco de Miranda, the Precursor), end up getting the city of Caracas to declare independence in 1811. This is immediately opposed by a lot of the other cities in Venezuela, either because they're royalists, or just don't want to be ruled in Caracas. This begins a disastrous civil war, and just as their military forces begin to run low, a huge earthquake levels the city on a holy day in March. People immediately call it divine retribution for the declaration of independence, and the whole thing collapses in June after Miranda tries to steal all of the gold. The republic collapses in late June, and the cycle repeats all over again because Bolivar just got exiled and ended up in a different city to try independence again.
Depending on when exactly in 1812 the story starts, things can be very different, basically.
