- April 4: Austria concedes independence to Galicia.
- May 2: The Congress of Budapest convenes between the states of the former Austro-Hungarian Empire, which are Austria, Hungary, Czechia, Galicia, Slovakia, Slovenia, Croatia, Bosnia, Serbia, and Montenegro. Bulgaria also attends. Several of the states that had not declared independence earlier are attending in attempt to gain their own land. In the end, all are successful.
- May 30: The Congress of Budapest announces that it has decided the borders. Borders are similar to Europe in OTL 1919, with these major exceptions: Austria has Italian territory not lost in OTL WW1 and other fringe territory, as well as Sudetenland. Hungary controls all of its former territory except for Croatia, and Slovakia, which keeps it a powerful state, albeit landlocked. In addition, a parliament is to be established in Hungary, which was demanded to represent minorities within the country.
- September 12: Austria announces its intention to join the German Empire. Wilhelm II and the democratic government react rather positively to the idea, especially with Sudetenland coming into the empire and Habsburg dominance being out of the question.
- September 17: Negotiations begin between Austria and Germany. The idea of a Kingdom of Hesse being created and the Kingdom of Hanover being recreated is demanded by Austria. Baden, Bavaria, Hesse-Darmstadt, Saxony, and Württemberg react very favorably, but is opposed by Prussia, who owns most of the territory.
- September 18: The next day of negotiations occurs. Austria, Baden, Bavaria, Hesse-Darmstadt, Saxony, and Württemberg continue to push hard for the change. They claim that since Prussia gained all of the land that was taken from Russia after the 1914 Incident, they should give up land they took over from fellow Germans as well. Saxony also wants the Province of Saxony within Prussia to transfer to their control.
- September 19: A compromise is reached. In exchange for Sudetenland becoming an "imperial territory", like Alsace-Lorraine, Austria will be allowed to join the German Empire as a Kingdom. The province of Hanover become the Kingdom of Hanover, ruled by the House of Hanover, while the Darmstadt branch of the House of Hesse will take control over the Prussian province of Hesse and independent Hessian territories (Hesse-Darmstadt) to become the Kingdom of Hesse. The southern part (with Anhalt serving as the division line) of the Prussian province of Saxony will be returned to Saxony. In addition, the two Mecklenburg duchies will be merged, and the Thuringian duchies will be merged into one electorate, Thuringia. Some of the duchies resist but no military conflict occurs.
- September 20: The United Kingdom, France, and Russia express their shock at the deal, which brings 8 million more people into the German Empire, and demand Austria remain separate. Germany and Austria refuse.
- September 21: Armies begin to be mobilized. Hungary and Italy jointly announce their support for Germany.
- September 23: Following negotiations with Germany, Britain retracts its demand and cancels mobilization, but France and Russia continue to demand that Austria remains independent. War appears to be unlikely, due to the neutrality of Britain. Shocked by the loss of support from Britain, France demands that Britain help them in a war against Germany. This would turn out to be one of the greatest blunders of French diplomacy in the 20th century, and one of the foreign policy successes of the aging Wilhelm II.
- September 24: Grossed by the aggressiveness of France, George V flatly refuses. This causes a deterioration in French relations with the United Kingdom.
- September 26: Russia cancels mobilization and calls off the situation after negotiations with Germany.
