Treuenbrietzen

The town has existed since the Middle Ages and the first written evidence about it is from 1217. From 1348 to 1350 the town remained loyal to the Wittelsbach Louis V the legitimate Margrave of Brandenburg since 1323 against the revolt of the False Waldemar. This event was the origin of the town's name "true" or "faithful" Brietzen. During the Reformation, Martin Luther came in 1537 to preach in the town, but his way to the church was blocked. He preached instead under a basswood, or lime tree, which is called to this day the Lutherlinde.

After the opening of the Sachsenhausen concentration camp in 1936, a sub-camp was opened in the town, where slave labourers were forced to work in the local weapons plants. Dr. Kroeber & Sohn GmbH was a local firm that made steam-, gas- and fluid-gauges, small internal combustion engines, and the Kroeber M4 light aircraft engine. They made BRAMO/BMW Flugwerk aircraft engine parts for the Luftwaffe. Treuenbrietzener Metallwarenfabrik GmbH had two factories that produced cartridges: Werk Sebaldushof north of the town and Werk Selterhof south of the town. It had three more plants in the towns of Roederhof , Metgethen, and Salzwedel.
