Count Reinhard IV of Hanau-Münzenberg succeeded in 1500 his father Philipp I of Hanau-Münzenberg in the government of the County of Hanau-Münzenberg. He served as co-regent from 1496 onwards. Reinhard IV was born the son of Philipp I, Count of Hanau-Münzenberg and his wife, Countess Adriana of Nassau-Dillenburg, his godfather was Prince-abbot Johann II of Henneberg-Schleusingen of the Fulda monastery. Reinhard IV made several journeys in his youth: in 1493 to the Palatine court at Heidelberg and in 1495 to the Diet of Worms. From 1496 to 1500, Reinhard IV acted as co-ruler alongside his father, disabled by old age, he was the first count to use the name Hanau-Münzenberg, to distinguish his line from his relatives in Hanau-Lichtenberg. The two lines had existed since the county was divided between Philipp the Elder and Philipp the Younger in 1458. Reinhard added the arms of the Lordship of Münzenberg to his coat of arms. In 1500, Reinhard exchanged some territories with the County of Isenburg, giving them Offenbach am Main and his share of Bracht and received the village of Bischofsheim in return, thereby ending a protracted conflict between the two neighboring rulers.

In 1503, he exchanged half the village of Trais for the share in Seckbach held by the Counts of Solms. In 1504, he purchased the other shares in Seckbach from their respective owners: the Schelme von Bergen family, the Farchen of Heidelberg family and the Glauburg family in Frankfurt; the County of Hanau-Münzenberg suffered badly during the Landshut War of Succession in 1504, from the Hessian troops passing through the county and from the Hessian occupation of Bad Homburg, which Hanau had purchased in 1487 for 19,000 guilders. This issue was mediated by Emperor Charles V at the Diet of Worms in 1521. Hesse had to reimburse Hanau with 000 guilders. In 1505, Emperor Maximilian I appointed Reinhard IV as his councillor. Reinhard IV was involved in several other disputes about his policies, his most prominent opponent may have been Götz von Berlichingen, who raided a convoy in the Kinzig valley, protected by Reinhard's troops. The Lords of Hutten joined the resulting controversy, claiming the raid had happened on their territory.

Reinhard IV married on 13 February 1496 with Katharina of Schwarzburg-Blankenburg. She received as dowry 4000 florins plus the Schwarzburg share of the mortgage of the imperial city of Gelnhausen. Reinhard IV and Katharina had four children: Anna Berthold, buried in the choir of St. Mary's Church in Hanau Philipp II Balthasar Reinhard IV died on 30 January 1512 and was buried in the choir of St. Mary's Church in Hanau.
