According to the succession in his line he should have been called Louis III, but he won Thuringia for his family and, in case of territorial expansion, it was customary to start counting from one.
Thanks to his marriage with Hedwig of Gudensberg he obtained the rule over an extensive heritage, after the death of his father-in-law, Count Giso IV, which led to the union of Thuringia and Hesse. In 1137 Louis became Landgrave of Hesse-Gudensberg as well.
His close relationship to the King Lothair III favoured his rise into the rank of a prince. After the death of Lothair, in 1137, Louis decided to support the Hohenstaufen in their struggle for power in the Reich against the Welf party. The Landgrave died on January 12, 1140 and was buried inside the abbey of Reinhardsbrunn.
