The Treaty of Christburg (modern Dzierzgoń in Poland) was a peace treaty signed on 2 February 1249 between the pagan Prussian clans, represented by a papal legate, and the Teutonic Knights. It is often cited as the end of the First Prussian Uprising, but it was not adhered to or enforced, especially after the Battle of Krücken in November of 1249, where Prussians massacred and tortured to death 54 knights who had surrendered.
