In books Allmenrod was first mentioned in 1131. The first official documents about the population in the town were found in 1854. At this time the village had a population 347 people. In the following years many people moved out of Allmenrod and into the bigger town and cities. In most cases this was the cause of the increasing poverty.
In the First World War there was a big mobilization of soldiers in the village. The total number of casualties resulted in 13 people. Their names were written down on the memorial of the cemetery. In comparison to the bigger towns, Allmenrod was not affected as much by the dearth. This depended on the high number of farms in this village. In the early twenties Allmenrod was connected to the electricity network. In these years the village also received a central water supply.
In the Second World War 15 villagers lost their lives. On March 29, 1945 the village was taken by the 4th Armored Division of the United States.
In the year 1946 Allmenrod took in more than 100 displaced persons. These were rehoused in many households. In 1950 the names of the fallen soldiers of World War II were transcribed on a war memorial of the cemetery.
