Engelbert I of Nidda

Engelbert I (died 1329), of the Ziegenhain comital house, ruled the County of Nidda from 1294, styling himself count of Ziegenhain. In 1294 he sold Neustadt castle and town to Archbishop Gerhard of Mainz. His feud with the Hospitallers ended only in 1315.

He married Heilwig of Isenburg-Büdingen in 1286, and their only child was Lukardis. In 1300 King Albert I allowed his fiefs to pass to her should he have no sons, and Engelbert died without male heir in 1329.
