Barnim is known for his engagement in piracy. He erected a fort and a port for this purpose in Ahrenshoop, which was destroyed by Rostock in 1395. He allowed the Victual Brothers, a pirate organization assaulting vessels of the Hanseatic League in the Baltic Sea, to use the Peene river as a winter refuge and the Bay of Greifswald as a basis.
On one of his expeditions, he was caught by the Hanseatic League in Kopenhagen"s port.
From 1400-1403, he aided the dukes of Mecklenburg-Werle in their campaigns against Lübeck. Barnim himself was wounded once at Lübeck"s gates.
In 1405, Barnim died of the Black Death. To avoid this fate, he went on a pilgrimage to Kenz near Barth, but died on his way in Pütnitz (a part of today"s Ribnitz-Damgarten) on 23 September 1405.
He was buried in Kenz, where a large wooden statue resembling Barnim was furnished.
