Moszczanka was founded as a Waldhufendorf in the second half of the 13th century, when it was part of medieval Piast-ruled Poland, and settled by German colonists.

[5][6] During the First Silesian War, the Prussian King Frederick the Great stayed briefly in Moszczanka.

After the reorganization of the province of Silesia, the rural community of Moszczanka belonged to the Landkreis Neustadt O.S.

In 1865 there were 43 farmers, 64 gardeners and 174 housekeepers as well as a farm, four water mills, a cloth factory, a whitewash, five bleaching yarns, six blacksmiths, a Catholic parish church and a school.

[11] A Polish citizen was murdered by Nazi Germany in the village during World War II.

After more than 50 young men were abducted by the Polish militia in October 1945, the remaining Germans who arrived in the British occupation zone a week later were expelled on 1 July 1946.

[13] After the defeat of Germany in World War II, the village became again part of Poland and was renamed Długomosty (changed to Moszczanka in 1946).
