Oststernberg district

Today, the former territory of the district is part of the Sulęcin County of the Lubusz Voivodeship in Poland.

The district included the four towns of Königswalde, Sonnenburg, Sternberg (Neumark) and Zielenzig.

In the spring of 1945, the district was occupied by the Soviet Red Army.

The local German population was expelled shortly thereafter and the influx of Polish and Ukrainian migrants began, some of whom came from areas east of the Curzon Line that had fallen to the Soviet Union.

At the end of its existence in 1945, the district comprised four towns and 73 other municipalities:
