Ulrich III
The "foreign" policy in the second half of the 14th century saw the Lords of Hanau – especially Ulrich III – in permanent conflict with the neighbouring city of Frankfurt. At one point Ulrich III was acting as representative of the emperor in the city and had laid claim to the imperial forest to the south of the city as well as the northern city districts of Bornheimerberg and Bockenheim. The city of Frankfurt, using its financial power by granting the emperor a large credit, managed to have Ulrich III removed as imperial representative and to take over the forest. The Lordship of Hanau kept most of area north of Frankfurt but never had another opportunity to take over Frankfurt itself again.
