Erfurt Union
After the Frankfurt Parliament disbanded, Frederick William IV, under the influence of General Joseph Maria von Radowitz, supported the establishment of the Erfurt Union—a federation of German states, excluding Austria—by the free agreement of the German princes. This limited union under Prussia would have almost entirely eliminated Austrian influence on the other German states. Combined diplomatic pressure from Austria and Russia (a guarantor of the 1815 agreements that established European spheres of influence) forced Prussia to relinquish the idea of the Erfurt Union at a meeting in the small town of Olmütz in Moravia. In November 1850, the Prussians—specifically Radowitz and Frederick William—agreed to the restoration of the German Confederation under Austrian leadership. This became known as the Punctation of Olmütz, but among Prussians it was known as the "Humiliation of Olmütz."
