Due to the Prussian neighborhood, the rulers of Eastern Pomerania from the Sobieslawic dynasty actively participated in the endowment of knightly orders that established their outposts in the Polish-Prussian and Pomeranian-Prussian borderlands. These included representatives of the Order of St. John, the Calatrawens, the Dobrzyn brothers or the Teutonic Knights. Relations between these orders and the dukes of East Pomerania were arranged in various ways. Periodic cooperation sometimes turned into sharp conflict. The princes then sought to remove the influence of the knightly orders in their dominions.
