On 5 March 1798, French troops completely overran Switzerland and the Old Swiss Confederation collapsed. On 12 April 1798, 121 cantonal deputies proclaimed the Helvetic Republic, "One and Indivisible". On 14 April 1798, a cantonal assembly was called in the canton of Zürich, but most of the politicians from the previous assembly were re-elected. The new régime abolished cantonal sovereignty and feudal rights. The occupying forces established a centralised state based on the ideas of the French Revolution.
