Scandinavia
These three Scandinavian kingdoms made the Kalmar Union in 1387 under Queen Margaret I of Denmark. However, in 1523, Sweden left the union. Because of this, civil war started in Denmark and Norway. Then, the Protestant Reformation happened, and Catholic and Protestant Christians fought each other. After things settled, the Norwegian Privy Council was abolished: it assembled for the last time in 1537. Denmark and Norway formed another union in 1536, and it lasted until 1814. It turned into the three modern countries Denmark, Norway and Iceland.
