The Frankfurt parliament failed as

After widespread revolts, not only across the 39 states but also across many other European nations such as France, a Parliament was called to discuss reforms and attempt to draft a constitution for a unified Germany. This was seen as being the best way of stopping the political unrest.

The constitution was completed in March 1849. This would unite the German states as a German Empire headed by a German Emperor.Government would be provided by an elected parliament that represented the populations of all 39 states.This new German Empire would replace the existing Bund.The Crown was offered to Prussia's Frederick William IV.

The Frankfurt Parliament and the attempt to unify Germany through political reform failed.

Frederick William refused to accept the crown because it had not been offered by the other German Princes, stating that he would not "accept a crown from the gutter".By late 1849, the movement for political reform had lost its impetus and the German Princes and the Austrian Emperor were able to regain control of politics in their territories.
