Creation in 2912 Edit
Hungarian Unionball became very weak after a violent famine that almost killed him. In the case of Bulgarian Empireball, he got involved in issues with the Turks - they were over 40% of the population, and they were murdering a lot of Bulgarians. When Hungarian-Bulgarian Commonwealthball got created, the Hungarians and Bulgarians restored their strength and wealth. He also purged those Turks.
The Great Balkan War in 2918 Edit
In 2918, after an agreement by four balkan countries to destroy him, he asked for help to Italian Empireball (another potential rival of them) to support him. Those balkan countries declared war in Hungarian-Bulgarian Commonwealthball, but he and his supporter were very prepared. In 2924, the war ended with the Hungarian-Bulgarian victory. Those four balkan countries were fully defeated and invaded, and then he decided to give away Greece and Albania to Italian Empireball for his big help.
