The fall of communism in Eastern Europe saw a lot of changes in most of the countries in this region. We can take Macedonia and Serbia as examples, both being former members of Yugoslavia.
After the fall of communism, Macedonia gradually started to change its economy towards market economy, which took six years, unfortunately with lot of corruption involved in the process. Serbia, on the other hand, being led by an extreme nationalist, got involved in war and initially was not so much focused on changing as much as it was for getting new territory.
Both countries turned to parliamentary democracies. Both of them experienced war, Serbia with NATO, Macedonia with terrorist groups from Kosovo in the western part of the country. Both of the countries started gradually moving into a direction to become westernized, as well as trying to get into the organization like NATO and EU, moving away from the ''East'' politically and economically.
Lot of reforms have been done so far, and the societies have been constantly changing, as well as the politics, and it seems that both countries will enter the aforementioned organizations and finally move forward.
