Wasungen was first mentioned in 874. The name Vuasunga means something like "wet grass".
In 1747, Wasungen experienced its greatest upheaval with the Wasungen War, when it was besieged by the troops of Saxe-Gotha. This was preceded by a fairly banal argument between two ladies in Meiningen Castle. After the death of Duke Bernhard I in 1706, the inheritance of his kingdom went to his three sons. At the same time, he decreed that his kingdom must remain in existence so that they had to rule it jointly. This led to some tension, especially with the youngest son Anton Ulrich, who was repeatedly deprived of his rights. When Anton Ulrich then took a commoner as his wife, there was great outrage. The reason for the war was ultimately very banal. At court, the noble ladies insisted on having preference over the commoner lady. Duke Anton Ulricht intervened in the argument and imposed punishments. This gave the rival House of Saxe-Gotha the reason to attack him and lay siege to Wasungen.
The Wasungen carnival, which has been documented since 1524, is more cheerful. Today, Wasungen is actually one of the carnival strongholds in the region.
The town centre of Wasungen is very compact and classically arranged within the former town wall. The houses are not all in the best condition, but this gives the old half-timbered town a certain charm. The only annoying thing is the very loud traffic on the B19, which seems even louder because of the tall houses.
