Erfurt Union
On November 29, 1850, the Treaty of Olmütz was concluded between Austria and Prussia with Russian participation. The treaty, seen by many as a humbling capitulation on Prussia's part to the Viennese Hofburg, saw Prussia submitting to the Confederation, reversing tack to demobilise, agreeing to partake in the intervention of the German Diet in Hesse and Holstein and renouncing any resumption of her union policy, and hence abandoning the Erfurt Union.
