The Revolutions of 1848 in the Austrian Empire were a set of revolutions that took place in the Austrian Empire from March 1848 to November 1849. Much of the revolutionary activity had a nationalist character: the Empire, ruled from Vienna, included ethnic Germans, Hungarians, Slovenes, Poles, Czechs, Slovaks, Ruthenians (Ukrainians), Romanians, Croats, Venetians and Serbs; all of whom attempted in the course of the revolution to either achieve autonomy, independence, or even hegemony over other nationalities. The nationalist picture was further complicated by the simultaneous events in the German states, which moved toward greater German national unity.
