[2] In 1249 a peace treaty was signed at the new castle between the victorious Teutonic Order and defeated local Old Prussians, in presence of papal legate, future Pope Urban IV.

[7][5] Following the victorious Battle of Grunwald, in 1410, Polish King Władysław II Jagiełło stayed in the castle, after it was abandoned by the Teutonic Knights.

[3] In the castle, the king received delegations from the city of Elbląg, which then pledged allegiance to him and recognized his authority.

[5] Local starosts granted privileges to the guilds of shoemakers, bakers, tailors, butchers, and wheelwrights.

[12] Until 1919 Christburg belonged to the administrative district of Regierungsbezirk Marienwerder in the German Province of West Prussia.

[15] Several months later the town was handed over to Poland, and was renamed Dzierzgoń, based on an Old Prussian Zirgūni name.

At the turn of 1945 and 1946, the Polish resistance movement carried out successful attacks against communists and Soviets, acquiring weapons, uniforms and money.

[15] The town was resettled by Poles from Polish areas annexed by the Soviet Union and Ukrainians expelled from southeast Poland in 1947.
