Silesian Przesieka, literally Silesian Cutting (Polish: Przesieka Śląska or Oseg, German: Schlesischer Grenzwald, Hag or Preseka, Latin: Indago) was a densely forested, uninhabited and unpassable area in the middle of Silesia, spreading from Golden Mountains in the south, along the Nysa Klodzka to the Odra, and then along the Stobrawa, reaching the towns of Namyslow and Byczyna in northern Silesia. Originally, the Silesian Cutting was a boundary, separating territories of two Western Slavic tribes, the Slezanie and the Opolanie. In the 12th century, along the Cutting a border of Lower Silesia and Upper Silesia was established.
For a long time, the Silesian Cutting was used as a natural military obstacle, protecting the area of Opole from raids of the Moravian and Czech tribes. However, it did not prevent the Hussites from invading Silesia in 1420 (see also Hussite Wars).
