This was originally for frankolio's Map of Germany victories in WWI and WWII thread, but then I realized he did want to have the sides switched up so I decided to just do whatever I felt like with it. Thus the world after the First Great War:
The POD is, Crown Prince Rudolf of Austria not only survives the assassination attempt at Mayerling, but kills his would-be-assassins in self-defense. When the assassins are examined it becomes apparent that they are agents of the French. The World press gets wind of the plot to kill Franz Joseph which then led to the plot to kill Rudolf for refusing to join in the plot to kill his father, and plasters it on every newspaper they can find. France becomes isolated diplomatically from much of Western Europe, forced to seeks friends in Russia and Japan, (and secretly Italy). The attempt on Rudolf's life causes him to reconcile with his wife and begin to reconcile with his father. When Sissi is assasinated in 1898, the Emperor and the Crown Prince finally finish their reconciliation. Rudolf becomes Franz Joseph's closest confidante and serves as his father's Chancellor. In 1899, Rudolf welcomes his son and heir, Franz Joseph into the world. He lobbies his father heavily starting in 1900, to reform the structure of the empire, if not to appease the ethnicities of the Habsburg Monarchy, then to ensure the legacy of the Habsburg Family and the rights of his grandson. The latter two arguements work and Franz Joseph orders a committee meet in Vienna, headed by Crown Prince Rudolf to draft a proposal for a Federal Empire. In 1904, Franz Joseph issues an Imperial Decree, dissolving the Dual Monarchy, and replacing it with the Federal Danubian Empire. He takes the position of Danubian Emperor, lowering Austria back to the status of Archduchy, and recognizing the rights of the Kingdom of Bohemia, Kingdom of Croatia, Kingdom of Galicia, Apostolic Kingdom of Hungary, Kingdom of Ruthenia, and Grand Principality of Transylvania.
The First Great War errupts in 1914, when Serbian Nationalists bomb several government buildings in Zagreb in retaliation for the occupation of Bosnia by the Federal Empire, and Bosnia's annexation into Croatia. They flee back into Serbia, and Danubia demands their extradition, supported by Germany, the Netherlands, Greece, Romania, and Italy (for the momement). The Serbs refuse and call on Russia, who in turn calls on France who in turn calls on Japan and Italy. Belgium unwisely decides to violate it's neutrality under pressure from France. Great Britain and America, while officially remaining neutral, heavily supply the Zagreb Coalition with material and harass French and Russia shipping.
Thus the world after the Treaty of Bad Ischl, ending the First Great War. The Zagreb Coalition has won resounding victory, and forced
terms on the Franco-Russian Alliance, including, the break up of Italy, into Habsburg dominated territories. The restoration of the Duchy of Burgundy under Charles V(Karl I of Austria OTL), the creation of the County of Champagne under Albert I, formerly Prince of Monaco, who is being compensated for the loss of Monaco to Burgundy. In Eastern Europe the victors install Habsburgs on the Polish and Ukrainian Thrones, and members of the Greek Royal Family on the Georgian and Armenian Thrones. While not part of the victorious coalition, Great Britain is honored with influence in Central Asia, and Germany and Britain partition China.
Greece and Armenia have seized on unrest in Ottoman Turkey, and with the support of Wilhelm II and Rudolf I(who assumed the throne in 1919 after the death of his father), and invaded the sick man of Europe to retake ancient claims.
