Carefully timed letters of protest from the people of Samogitia reached the Roman Curia at the same time as those of numerous European courts and guilds of cities in eastern Europe. Fomented by Grand Duke Vytautas, the first Samogitian uprising seized the region from 1401 to 1404 and ceased when a peace treaty was signed that recognized the crusaders' authority over the region. In 1409, Vytautas argued for a second insurrection. With open support for rebellion in Teutonic Order territory, Grand Master Ulrich von Jungingen called for war. On August 6, 1409, von Jungingen's herald brought a formal challenge from the order to the king of Poland. This signaled the beginning of the (Great Quarrel), as the Teutonic Knights called the Polish–Lithuanian–Teutonic War.
