History
In 1300 Mikołaj of Rzeczyca (Mikołaj z Rzeczyce) sold Dziedno to Cistercians from Byszewo.

During the German occupation of Poland (World War II), in 1941, the occupiers carried out expulsions of Poles, who were deported to the Potulice concentration camp, while their farms were then handed over to German colonists as part of the Lebensraum policy.
