When the Second Crusade was called, many south Germans volunteered to crusade in the Holy Land. The north German Saxons were reluctant. They told St Bernard of their desire to campaign against pagan Slavs at an Imperial Diet meeting in Frankfurt on 13 March 1147. Approving of the Saxons' plan, Eugenius issued a papal bull known as the Divina dispensatione on 13 April. This bull stated that there was to be no difference between the spiritual rewards of the different crusaders. Those who volunteered to crusade against the pagan Slavs were primarily Danes, Saxons and Poles, although there were also some Bohemians. The Wends are made up of the Slavic tribes of Abrotrites, Rani, Liutizians, Wagarians, and Pomeranians who lived east of the River Elbe in present-day northeast Germany and Poland.
