After 1343 the political activities of Casimir the Great were especially aimed toward subordination of Red Ruthenia. It was also the topic of the king's meeting with the Grand Master of the Order of the Teutonic Knights Winrich von Kniprode, held in Malbork (Marienburg) in October 1365. The purpose was to ascertain at least sympathetic neutrality of the Order during the expedition to Volhynia against the Lithuanians that was planned for the following year. The state of bilateral relations fostered the cooperation (the last short misunderstanding was the conflict about Rajgrod in 1360) and the intensification of fights between the Order and Lithuania was also helpful.
