UNION OF AUSTRIA AND HUNGARY IN 1867 is a good example of such a marriage. The Italian and German campaigns for national unification altered the balance of power in continental Europe. These campaigns challenged the dominance of Austria's Habsburg Monarchy.
While Italy and Germany were each coming together, the Austrian Empire was coming apart. Within its boundaries lived Austrian Germans, the Magyars of Hungary, Slovenes, Poles, Czechs, Slovaks, Ruthenians, Romanians, Serbs, and Croats. Its people practiced the Roman Catholic, Protestant, Eastern Orthodox, and Muslim religions. Little other than geography held these groups together.
Austria's defeat at the hands of French and Piedmont forces in 1859 and its crushing loss to Prussia in the Seven Weeks' War crippled Austria's influence in Europe and encouraged resistance within the borders of its empire. Faced with the dual threat of a rapidly industrializing German state and a unified Italy, Austria courted a new political partner to prevent the further erosion of its power.
During the revolutions of 1848, Magyar leaders of Hungary and Czech leaders from Bohemia had asserted their independence from Austrian rule. The Magyar leader LAJOS KOSSUTH helped establish a parliamentary democracy with the passage of the March Laws of 1848. Austrian military forces crushed the Czech revolt, but Kossuth's HOME DEFENSE ARMY held firm. Soon afterwards Kossuth was elected president of the new Hungarian republic. But Austrian forces, with the help of 100,000 Russian troops, reasserted control over the defiant Magyars. Kossuth fled to exile in Turkey.
