Büdingen
Büdingen was an Isenburg lordship in the Wetterau east of Frankfurt. Emperor Louis IV granted it market rights in 1330; Heinrich II of Isenburg was its lord in 1337.
From 1442 its rulers styled themselves counts of Isenburg-Büdingen. Büdingen turned Protestant in 1521, and in 1712 Count Ernst Casimir I invited Huguenots and Waldensians to settle outside its Lower Gate. The county was mediatized to Isenburg in 1806 and assigned to Hesse-Darmstadt in 1816.
