Criminals from the Holy Roman Empire

Pier Gerlofs Donia (c. 1480 – 28 October 1520) was a Frisian rebel leader and pirate. He is best known by his West Frisian nickname Grutte Pier ("Big Pier"; in the pre-1980 West Frisian spelling written as Greate Pier), or by the Dutch translation Grote Pier, which referred to his legendary size and strength.

Gabriel Brühl (died 1743) was a well-known robber in the then Duchy of Limburg, whose criminal career started in the 1720s and ended with his being hanged in 1743.

Eppelein von Gailingen, latinized as Apollonius von Gailingen (born c. 1315 in Illesheim, Middle Franconia; died 15 May 1381 in Neumarkt in der Oberpfalz) was a famous German robber baron in the Middle Ages.

Count Frederick of Isenberg (Friedrich von Isenberg) (1193 – 15 November 1226) was a German noble, the younger son of Count Arnold of Altena (died 1209). His family castle was the Isenburg near Hattingen, Germany.

Hans Kohlhase (c. 1500 – 1540), according to early modern German accounts, was a merchant whose grievance against a Saxon nobleman developed into a full-blown feud against the state of Saxony, thus infringing the Eternal Peace of 1495. The campaign culminated in Kohlhase's execution in March 1540.
