The degree of growth in German nationalismThe Frankfurt Parliament
German nationalism had grown in the early 19th century due to Prussian ambition, the rise of liberal ideas and popular rebellion. However, the reassertion of Austrian power limited this growth.
The Frankfurt Parliament was called to discuss reforms and attempt to draft a constitution for a unified Germany. This was seen as the best way to stop the political unrest.
The constitution was completed in March 1849:
the German states were to be united as a German Empire headed by a German Emperor
government would be provided by an elected parliament
the government would represent the populations of all states
the new German Empire would replace the existing Bund
the Crown was offered to Prussia's Frederick William IV.
But the Frankfurt Parliament and the attempt to unify Germany through political reform failed. Frederick William was not a strong enough leader to unite Germany. He refused to "accept a crown from the gutter" because it had not been offered by the other German Princes
