Ulrich IV, Lord of Hanau

Ulrich IV (c. 1330/1340–1380), son of Ulrich III, was Lord of Hanau from 1369/1370. He joined the Star League against Hesse and killed the Hessian ally Frowin of Hutten; Frowin's relatives captured him, and his uncle, the Bishop of Speyer, won his release for a 7500-guilder ransom.

In 1372 he sold Babenhausen to the Bohemian crown and received it back as a fief; in 1375 he finalized the Hanau primogeniture decree. He died in 1380 and was buried in Arnsburg Abbey.
