The Austrians defeat the Piedmontese at the Battle of Novara.
The Battle of Novara (or Battle of Bicocca; Bicocca being a borough of Novara) was one of the battles fought between the Austrian Empire and the Kingdom of Sardinia during the First Italian War of Independence, within the era of Italian unification. Lasting the whole day of 22 March 1849 and ending at dawn on 23 March, it resulted in a severe defeat and retreat of the Piedmontese (Sardinian) army.
The Austrian Empire (German: Kaiserthum Oesterreich, modern spelling Kaisertum Österreich) was a Central-Eastern European multinational great power from 1804 to 1867, created by proclamation out of the realms of the Habsburgs. During its existence, it was the third most populous empire in Europe after the Russian Empire and the United Kingdom. Along with Prussia, it was one of the two major powers of the German Confederation. Geographically, it was the third-largest empire in Europe after the Russian Empire and the First French Empire (621,538 square kilometres or 239,977 square miles). Proclaimed in response to the First French Empire, it partially overlapped with the Holy Roman Empire until the latter's dissolution in 1806.
The Kingdom of Hungary—as Regnum Independens—was administered by its own institutions separately from the rest of the empire. After Austria was defeated in the Austro-Prussian War of 1866, the Austro-Hungarian Compromise of 1867 was adopted, joining the Kingdom of Hungary and the Empire of Austria to form Austria-Hungary.
