Frisian Crusaders - Fierce Fighters Without Lords

From the First Crusade onwards, men from Frisia, the North Sea coast between the Zuiderzee and the Weser, took the cross. French chroniclers called them Frisons. Their homeland had no territorial prince, and later Frisian tradition made them heroes of the crusades. But what do the sources actually say about these fighters without lords?

Frisians at Antioch
The earliest trace is in Guillaume de Tyr, archbishop and chronicler writing around 1180. Describing the siege of Antioch in 1097 and 1098, he lists the peoples in the camp of Godefroy de Bouillon, duke of Lower Lotharingia: Lotharingis, Frisonibus, Suevis, Saxonibus, Franconibus et Bavaris [Lotharingians, Frisians, Swabians, Saxons, Franconians and Bavarians] [1]. The Frisians appear here as one group among the peoples of the Empire, not as a separate army.

The voyage of 1217 and 1218
The best documented expedition is the one of the Fifth Crusade. An anonymous participant, probably a cleric, described it in the De itinere Frisonum [On the journey of the Frisians], which survives only because Emo, abbot of the Premonstratensian house of Bloemhof (Wittewierum), copied it into his chronicle; the single manuscript is kept in Groningen [2]. The fleet left Frisia on 31 May 1217, joined other crusaders at Dartmouth in early June and reached Acre on 26 April 1218 [2].

On the way the Frisians took their own decisions. Asked by Bishop Soeiro of Lisbon to help besiege the Muslim stronghold of Alcácer do Sal, they refused and kept their course [2], and they raided coastal towns of al Andalus, deeds the author presented as part of their crusade [2].

Damietta in Frisian memory
Two and a half centuries later, Frisian historians turned this crusading past into a national story. Texts written between about 1464 and 1479 tell how the Frisians took the cross in masses after the preaching of Oliver, schoolmaster of Cologne, and how at Damietta in 1218 they took the chain tower from a wooden castle built on their ships [3]. The same texts link Frisian deeds from Lisbon in 1147 to Damietta in 1218 and Aachen in 1248, each paralleled by a biblical story to show that God protected the Frisians as a chosen people [3].

Without lords?
Frisian freedom meant the absence of a territorial lord: the land consisted of self governing communal districts [3]. The fifteenth century stories were written to defend that freedom when Burgundian pressure threatened it [3]. The image of Frisian crusaders as free men without lords is therefore partly a later construction. On campaign they did act as a group, as the decisions of 1217 show [2], but the contemporary accounts are few.

The evidence suggests that Frisians fought in the crusades from Antioch to the Fifth Crusade and acted as a self conscious group at sea. Much of their heroic reputation, however, was shaped in the fifteenth century, when the memory of the crusades served to defend Frisian freedom.
