The village was first mentioned in 1326 in the register of Peter's Pence payment among Catholic parishes of Oświęcim deaconry of the Diocese of Kraków under two names: Medzwna seu Cuncendorf.

[3] Afterwards, the village passed under Bohemian (Czech) suzerainty, and in the 15th century, it became part of the newly formed Duchy of Pszczyna.

During the political upheaval caused by Matthias Corvinus the duchy was overtaken in 1480 by Casimir II, Duke of Cieszyn from the Piast dynasty, who sold it in 1517 to the Hungarian magnates of the Thurzó family, forming the Pless state country.

In the War of the Austrian Succession most of Silesia was conquered by the Kingdom of Prussia, including the village, and in 1871 it became part of the German Empire.

During the German occupation (World War II), in January 1945, the death march from the Auschwitz concentration camp passed through Miedźna, and 42 prisoners, including 29 women and several children were buried in the village.
