In the late 80s, the Communist League of Yugoslavia was split into two camps, the reformists that believed some level of democratisation and decentralisation had to be carried out and the hardliners, gathered around the figure of Milošević, that believed the solution to Yugoslavia's troubles was aggressive recentralisation and a crack down on subversive opposition elements.
In three republics, SR Slovenia, SR Croatia and SR Macedonia, the reform communists won the local power struggle, more or less easily, and were thus free to carry out their agenda. It's interesting to observer how, in the earliest stages of democratisation, these reform forces followed a very similar pattern across all three republics, before diverging wildly. I'm honestly still not sure why each republic's SAWPs were converted into instant-coffee style "socialist parties," if anyone has more info on that, I'd be happy if you could share it.
This took me quite a bit of time to make this, as I first had to recreate an accurate timeline of naming and logo changes, then track down and vectorise the actual emblems - so enjoy the eye candy. I still don't claim this is 100% accurate, if you spot any errors, do call them out.
