Frederik van Blankenheim studied law in
Paris and was named bishop of Strasbourg in 1375. His reign was not a success, and with help from
William I of Guelders and Jülich he was transferred to
Utrecht, where he proved to be an able ruler. Supported by the
Lichtenbergers faction, he managed to maintain his rights over the cities in the bishoprics, the local nobility and the surrounding counties of
Holland and
Guelders. He strengthened ecclesiastical authority in the
Oversticht and forced the city of
Groningen to recognise his authority. In 1407 he granted city rights to
Coevorden. ==Wars==
