Poppo was the scion of a comital family from the Imperial Landgraviate of Thuringia. It corresponds only loosely to the medieval Landgraviate of Hessen. In 1433, the town passed back to the Landgraviate of Hesse. He also held the Landgraviate of Nellenburg and the County of Hohenberg. Staden was born in Homberg in the Landgraviate of Hesse. In 1684 he commanded a Dragoon regiment in the service of the Landgraviate of Hesse-Kassel. The Landgraviate of Hesse () was a principality of the Holy Roman Empire. In 1785 they moved to Kassel when William succeeded to the landgraviate. Schweppe was born in Witzenhausen in the Landgraviate of Hessen-Kassel. Thuringia became a landgraviate in 1130 AD. The remaining Thuringian landgraviate fell to the Wettin margrave Henry III of Meissen. The Landgraviate of Hesse-Homburg and the Free City of Frankfurt were also to the east. As a consequence, the landgraviate was divided. Hesse was ruled as a Landgraviate, Electorate and later as a Grand duchy until 1918. After Otto inherited the whole Landgraviate, he resided alternately in Kassel and Marburg.
