The Arumer Zwarte Hoop, meaning "Black Army of Arum" (West Frisian: Swarte Heap) was an army of peasant rebels and mercenaries in Friesland fighting against the Habsburg authorities from 1515 to 1523. For four years they were successful under the former farmer Pier Gerlofs Donia. Led by his Lieutenant Wijerd Jelckama from 1519 they slowly lost ground and were captured and executed in 1523.
