A memorial column from 1574 expresses the gratitude of the province for the construction of the dikes after the great floodings of 1570. Later, when the Council announced a decree deseating Don John of Austria, he was suspected to take side for the latter. Van Achelen was incarcerated and released soon thereafter.
He redeemed himself only eight years later, when he was awarded the knightly insignia.
In 1550 he was nominated member of the Friesian Regional Council by Charles V. In 1570 he became president of the Friesian State Council. He became a member of the Privy Council, then on 18 August 1598 president of the Greater Council of Mechelen.
