Landgraviate of Hesse-Darmstadt
The Landgraviate of Hesse-Darmstadt (German: Landgrafschaft Hessen-Darmstadt) was a State of the Holy Roman Empire, ruled by a younger branch of the House of Hesse. It was formed in 1567 following the division of the Landgraviate of Hesse among the four sons of LandgravePhilip I.
The residence of the landgraves was in Darmstadt, hence the name. As a result of the Napoleonic Wars, the landgraviate was elevated to the Grand Duchy of Hesse following the Empire's dissolution in 1806.
