== Prelude to Unification ==
Nearly 40 years after the emergence of Protestantism in Europe, a religious war sparked across the continent on the Day of Ruination (March 1st, 1556). This was the beginning of the War of the Leagues, between the Protestant League and the Catholic League of Verdun. This was also the beginning of the War of Hungarian Succession, where the Habsburg realm of Royal Hungary fought against the Polish-ruled Kingdom of Hungary for control of the Pannonian Basin (Hungary's entire nation). 
11 years passed; it was now 1567. The Habsburgs had pushed the Poles back to the Carpathian mountains, and a stalemate was weighing heavily on both sides. Suddenly the Habsburgs were distracted by a new frontline to the south, when they were suddenly invaded by the Balkan League and the Italic Union in November 1567, with Sardinian support to Italia. In 1568, Italia and Sardinia were briefly distracted by a new front which threatened the Italic core territories, but Italia managed to defeat those enemies quickly. When they returned to the front against Austria, Polish morale had recovered.
"We are not yet lost. After so much bloodshed, I can finally save you... brother." - Poland to the Kingdom of Hungary, February 1569.
The Polish armies charged into Hungary, driving the Austrians all the way back to the Danube river. In early April 1569, the Austrians stopped retreating, and they faced the Poles at the Battle of Pest, which lasted several weeks. The Poles eventually won, pushing the Austrians even further back. Once the Poles reached Pressburg (today Bratislava), in celebration, the Union of Lublin was signed on July 1st.
Poland, Lithuania and Hungary... united.
== Ending the War of the Leagues ==
Croatia was so frightened by the Commonwealth's formation that they immediately requested peace. A couple of months later, the Hungarian contingent of the Commonwealth government travelled to meet Italia and the Balkan League, sign the Treaty of Zagreb, and hence give up all Hungarian lands south of the Drava river. However, the Hungarian territory west of the Danube was still under Habsburg control, and the Polish-Hungarian advance in the area slowed down dramatically. Then in February 1571, several Protestant League leaders travelled to Bohemia to attend the Peace of Prague negotiations. The Commonwealth accepted the loss of their Livonian vassal to Sweden, as well as the loss of eastern Lithuanian borderlands to Russia. This saw an end to most of the fighting, and the disbandment of the Protestant League and the League of Verdun. 
Austria and Prussia were not invited to the negotiations, and suddenly they found themselves at the mercy of the Poles. Polish and Lithuanian armies quicky overran Prussia, as Polish, Hungarian, Italic and Bohemian armies closed in on Austria. As the Commonwealth eliminated Royal Hungary, Bohemia dealt the final blow to Vienna. As per the Peace of Prague, Prussia was absorbed, without autonomy, into the Polish contingent of the Commonwealth, strengthening Polish influence over the southern Baltic Sea.
