[1] The 31-member or 30-member[nb 1] delegation from seven Samogitian regions (Ariogala, Kaltinėnai, Knituva, Kražiai, Medingėnai, Raseiniai, and Viduklė) arrived to Königsberg around the pentecost.
[2] They promised their loyalty to "their king" Vytautas and guaranteed trade freedom for the Knights in Samogitia.
[1] Vytautas the Great waged a civil against his cousin Jogaila, Grand Duke of Lithuania and King of Poland.
In order to secure Teutonic support in the civil war, Vytautas signed the Treaty of Lyck and granted Samogitia up to the Nevėžis River to the Knights on January 19, 1390.
[3] Samogitia was important for the Knights as this territory physically separated them from uniting with the Livonian Order in the north.
