From 1740, dualism between the Austrian Habsburg Monarchy and the Kingdom of Prussia dominated German history. In 1772, 1793, and 1795, Prussia and Austria, along with the Russian Empire, agreed to the Partitions of Poland. During the period of the French Revolutionary Wars, the Napoleonic era and the subsequent final meeting of the Imperial Diet, most of the Free Imperial Cities were annexed by dynastic territories; the ecclesiastical territories were secularised and annexed. In 1806 the "Imperium" was dissolved; France, Russia, Prussia and the Habsburgs (Austria) competed for hegemony in the German states during the Napoleonic Wars.
