1. The Polabian Crusade

The participation of a unit of Polish troops in the Levantine expedition of Conrad III and Louis VII did not exhaust the scope of Polish involvement in the wave of enthusiasm for crusading which in 1147 swept most of Europe. More or less at the same time that the crusader armies of the French and German kings were heading east, there was a rival crusading initiative being enacted in the lands of the Polabian . These events are known in historiography as the Wendish, Slavic or Polabian crusade, and, despite the many works written about them, remain one of the most mys- terious episodes of the twelfth-century crusading movement.1 The laconic

From the perspective of the present work, the Annales Magdeburgenses are of cru- cial significance because they show that apart from Saxon, Westphalian, Burgundian, Lotharingian, Frankish, Danish and Moravian crusaders in the northern expeditions, there was also an unnamed Polish duke at the head of a sizeable body of troops.2 Before we begin the deeper analysis of this document, however, the present state of knowledge on the circumstances of the initiation of the Polabian crusade needs to be briefly presented. As was mentioned in the previous chapter, the propaganda and recruitment activities preced- ing the Second Crusade affected with especial intensity. The efforts of its organizers, with St Bernard of Clairvaux and Abbot Adam of Ebrach at the head of the campaign, were met with spectacular success. By the end of 1146, participation in the new Levantine crusade had been declared by a series of representatives of the political elite of the Reich, including King Conrad III, his nephew the Duke of Swabia, Frederick Barbarossa as well as the leader of the opposition—the Duke of ,

Ubi in una societate convenerant Fridericus archiepiscopus Magadaburgensis, Rotholfus Halverstadensis episcopus, Wernherus Monasteriensis, Reinhaldus Mersburgensis, Wickerus Brandeburgensis, Anshelmus Havelbergensis, Heinricus Moraviensis episcopi et Wibolt Corbegensis abbas, Conradus marchio, Adalbertus marchio, Fridericus palatinus comes, Hermannus palatinus comes cum multis comitibus et armatis bellatoribus sexaginta milibus! Interim in alia societate se in unum collegerant Albero Bremensis archiepiscopus, Thietmarus Fardensis episcopus, Heinricus dux Saxonie, Conradus dux Burgundie, Hartwigus princeps prenobilis cum multis comitibus et nobilibus et ceteris armatis numero quadraginta milibus pugnatorum. Rex eciam Dacie cum episcopis terre illius et cum universo robore gen- tis sue, maxima multitudine classium collecta, circiter centum milibus exercitum paraverat. Iter frater ducis Poloniae cum viginti milibus armatorum exiverat. Cuius etiam frater maior cum infinito exercitu adversus Pruscos crudelissimos barbaros venit, et diutius ibi moratus est. Contra quos etiam Rutheni, licet minus catholici tamen christiani nominis karacterem habentes, inestimabili Dei nutu cum maximis armatorum copiis exiverunt.
