1848 saw major changes across Europe as rebellions and revolts broke out in response to conservative rule and calls for greater political and economic reforms. The Chartist Movement agitated for broader voting rights in Britain while factory acts and the repeal of the Corn Laws reduced tariffs. In Italy, rebellions challenged Ferdinand II's rule in the Two Sicilies and there were calls to unite the country. Metternich lost power in Austria and Hungarians rebelled as Germans attempted national unification through the Frankfurt Parliament, despite the refusal of the Prussian king to accept the imperial crown.
