Hessel Hermana

Hessel Hermana is the fourth potestaat of Friesland.

Supposedly from Sexbierum (chosen 869 – died c. 876), he does not appear in historical sources until the late 16th century.

His name is then attached to the Dane Rudolf Haraldsson who invaded Oostergo in order to recover Danegeld (tribute) by force.

Rudolf Haraldsson was killed in battle and the Frisians won, but Hessel also died.

His predecessor was Adelbrik Adelen and he was succeeded by Igo Galema as potestaat.
