[1][2] 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.
As ally of William VI, Count of Holland, he took part in the Arkel-war of 1406, through which he gained possession of Hagestein.
Frederik van Blankenheim died on October 9, 1423, and was buried in the Dom Church.
