June 7, 1066 - Gottschalk Murdered by the Obotrites
Gottschalk was a prince of the Obotrite Confederation which existed in what are now the northern German regions of Mecklenburg and Holstein. The Obotrites loosely banded together based on who they were fighting like Swedes, Danes, and Saxons. The Obotrites were a pagan people despite influence from neighboring Charlemagne, and Gottschalk desired to bring his people to Christ. He worked tirelessly to accomplish this goal, but on June 7, 1066, he was overthrown by the pagans and killed. He was eventually made a saint.
