Nidda
Nidda was a small county in the northern Wetterau, built from fiefs of Fulda Abbey. In 1337 John I of Ziegenhain ruled it together with Ziegenhain, having united the counties through his marriage to Lukardis.
Debt forced John to sell a quarter of Nidda to Mainz in 1344. The county became immediate to the Empire in 1420, but on the childless death of John II in 1450 it passed with Ziegenhain to Hesse. Nidda later belonged to Hesse-Marburg and Hesse-Darmstadt.
