While the twelfth century is generally associated with great social, political and economic transformations and cultural development in Western Europe, there was one area of Medieval Europe which did not fit the general scheme. This area, called Połabie was inhabited by Polabian tribes, who resisted influences from their neighbours and remained pagan well into the twelfth century. The area was an object of intense political interest for three powerful neighbours, which manifested itself in numerous attempts to Christianize the region. The Christianization of the Polabian tribes is described in, among other sources, the Chronica Slavonorum, which is preserved in AM 30 fol.
