Again destroyed and depopulated during the Swedish invasion of Poland in 1656, the village was soon again repopulated with Polish settlers. After the Partitions of Poland it fell to Prussia. The village was a strong center of Polish resistance to attempts at Germanisation, forced by the Prussian and later German administration. In 1863, local priest Juliusz Grzymała hid Polish insurgents in the parish, from 1872 the parish brought Polish newspapers to the village. In 1881 a Polish library was created, which was to be a counterweight to the official German school. Near the end of World War II, in January 1945 Soviet soldiers tortured and murdered the local Polish parish priest Paweł Chmielewski. After the war Klebark Wielki was reintegrated with Poland.
