Repeated French efforts to annex the Left Bank of the Rhine began with the devastating wars of King Louis XIV. French forces carried out massive scorched earth campaigns in the German south-west. This policy was fully implemented during the Napoleonic Wars with the creation of the Confederation of the Rhine in 1806–1813. In the two centuries from the Thirty Years' War to the final defeat of Napoleon I, the German inhabitants of lands by the Rhine suffered from repeated French invasions.
