In 1525 it became part of the Duchy of Prussia, remaining a part and fief of Poland, after the secularization of the Teutonic Knights. It was the seat of starosts (local administrators) from 1525 to 1616, when they relocated to Olecko.[4] In 1529, the local church became a Protestant parish church, in which Polish services were held.[5] As of 1600, the population of the village was solely Polish.[2] The village was included within the Kingdom of Prussia in 1701 and the German Empire in 1871. Jerzy Wasiański, the author of the most popular 18th-century Polish hymnal in Masuria, was the pastor in Straduny until 1737.[6] From 1818 to 1945, it was administered within Landkreis Lyck in the province of East Prussia. For centuries inhabited by Poles, in the 19th century, the village was subjected to Germanisation policies.
In a plebiscite after World War I to determine if the village would remain in Germany or become part of the newly restored Second Polish Republic, the majority of voters chose to remain in German East Prussia.
The village was largely untouched by fighting during World War II. The last Lutheran service at the local church was held on 29 October 1944. Because the church's rectory was used by Wehrmacht staff, it was destroyed shortly before the arrival of the SovietRed Army on 18 January 1945. The Wehrmacht destroyed three nearby bridges over the Ełk River in order to impede the Red Army; two of the bridges were rebuilt by German prisoners of war after hostilities ended.
In 1945 the village became again part of Poland according to the Potsdam Agreement under its historic[3] Polish name Straduny. The church was reconsecrated as a Roman Catholic church on 3 May 1946.
