ENAn important element in current historical research is the analysis of diplomatic relations regarding the former Polish-Lithuanian Commonwealth, including the Grand Duchy of Lithuania. They show the history of the state and its internal and foreign policy from a different historical perspective. In 1700 the Great Northern War broke out, which changed the balance of political forces in Central and Eastern Europe for the next decades. Foreign court diplomats were interested in this war, including Philipp Plantamour, secretary of the British ambassador in Berlin. He sent to London his reports, in which he placed not only information about military operations during the war, but also about the most important families in Lithuania and their political rivalry. An analysis of these diplomatic reports will answer the question of how the Great Northern War and the internal situation in the Grand Duchy of Lithuania in Western Europe was seen. It will also be interesting if the reports of Philipp Plantamour reliably presented the events described in the reports, were they true and contained unknown information so far. [From the publication]
