Croatian Civil War

After John Paul Della Tiny imprisoned his wife Poolivia Prasnjak (Il Pras) in 2014 he quickly converted to true Catholicism and had every Novus Ordo chapel converted to a Latin Francis one, with conditional Holy Orders for every novus ordo cleric within Croatian borders. 

In 2015, he gave much of Slovenia to Austria in exchange for military lend leases and financial support from the HRE. On March 2nd 2015 he launched a military invasion into Serbia, annexing it in late December, which resulted in a war with AC and the Ottoman Empire. Surprisingly, he won and AC pulled out of Serbia.

During this, the Novus Ordo managed to sneakily break Il Pras out of prison, and through secret funding gathered a large rebel force in Raguza and southern Dalmatia. On February 10th, 2016 she formally declared independence and began a war against Croatia which had recently declared a change in ideology from National Bolshevism to Clerical Fascism, which angered many Dalmatian Croats. 

The war waged on for many months, and in 2017 it was a complete stalemate, with barely any gains from either side. The HRE would send several naval invasions from Italy, landing in the Natbol capital of Raguza, and after a short manhunt, would capture Il Pras in the city of Triabenia. On June 5th, 2017 Il Pras would be publically hung in the streets of Zagreb, and the war was over. 

Today Croatia is a strong, growing nation that went from being a National Bolshevik Novus Ordo hellhole to a prosperous Fascist Catholic nation, fully supported by the HRE.

Pope Francis had taken some parts of the Dalmatian coast for access to the Adriatic.
