Hungary against the Habsburgs:
March 3, 1848
For many years, Hungary and Austria had shared the same monarch (who was emperor in Austria, but king in Hungary), but not the same laws. Unlike Austria, and the rest of the Habsburg domains, Hungary had her own constitution. Hungary had her own diet, which was supposed to meet every three years in the city of Pressburg (or Poszony or Bratislava), located on Hungary’s border with Austria.
Hungary had performed great and important services for her Habsburg rulers, both in the wars against Friedrich the Great of Prussia and in the struggle against Napoleon. Hungarians had suffered much for their Habsburg kings.
