Yes, it was multicultural society, in some things similar to US, in other very similar to Soviet union. Maybe something between. Lot of different nations and religions, with long history of conflicts between them, but unite together under the socialistic system.
Then came collapse of state because economic reasons, politic reasons (change from socialistic to “democratic” system) and somehow someone pulled all differences between different nations and religions and turned it against each other.
Then hate came, and people from all sides just fueled hate etc.
It is very short and simplified explanation, but it is true. Yes there are some similarities.
