Hesse-Homburg was formed in 1622 by Landgrave Louis V of Hesse-Darmstadt. It was to be ruled by his son, George II. Hesse-Homburg did not become independent from Hesse-Darmstadt until 1668. Hesse-Homburg was divided into Hesse-Homburg-Bingenheim and Hesse-Homburg, but was reunited in 1681. From 1806 to 1815, Hesse-Homburg was a part of the Grand Duchy of Hesse. In 1815, the Congress of Vienna recognized the independence of Hesse-Homburg, which was increased by the addition of Meisenheim. Hesse-Homburg consisted of two parts: the district of Homburg on the right side of the Rhine River and the district of Meisenheim, on the left side. On July 7, 1817, Hesse-Homburg joined the German Confederation as a sovereign state. It was the only principality that was not one of the founding members of the Confederation, other than the Duchy of Limburg and Duchy of Schleswig. The landgraviate was combined with the Electorate of Hesse-Kassel, Duchy of Nassau and the Free City of Frankfurt to form the Prussian province of Hesse-Nassau in 1866 after the Austro-Prussian War.
