 The outcome was that France relinquished its ancient claim on Flanders in 1528.From 1515 to 1523, Charles's government in the Netherlands also had to contend with the rebellion of Frisian peasants (led by Pier Gerlofs Donia and Wijard Jelckama).The rebels were initially successful but after a series of defeats, the remaining leaders were captured and decapitated in 1523.
