1. French Revolutionary and Napoleonic Wars

Were a series of conflicts between France and several European monarchies between 1792 and 1815. They encompass first the French Revolutionary Wars against the newly declared French Republic and from 1803 onwards the Napoleonic Wars against First Consul and later Emperor Napoleon Bonaparte. They include the Coalition Wars as a subset: seven wars waged by various military alliances of great European powers, known as Coalitions, against Revolutionary France - later the First French Empire - and its allies.

1.1. War of the Fourth Coalition

Was a war between the French Empire and a coalition of European monarchies, mainly Prussia and Russia.

1.1.1. Prussian Campaign (War of the Fourth Coalition)

Was a French military campaign in Prussia during the War of the Fourth Coalition.

  • October 1806: At the double Battle of Jena-Auerstedt on 14 October, Napoleon defeated a Prussian army led by Frederick Louis.
  • October 1806: French Marshal Jean-Baptiste Bernadotte defeated Eugene Frederick Henry, Duke of Württemberg, at the Battle of Halle and chased his forces across the Elbe River.

1.1.2. Peace of Tilsit

Were a series of treaties that ended the War of the Fourth Coalition.

  • July 1807: The treaty signed between Prussia and France at Tilsit, following the War of the Fourth Coalition, was highly disadvantageous to Prussia. As a result of this agreement, the Kingdom lost most of its Polish territories to the newly created Duchy of Warsaw.

The remnant territories occupied by France in Germany were evacuated.
