The area around Friedberg is known as the Wetterau, not because of the German word Wetter meaning weather, but because there is a small river named the Wetter (a tributary of the Nidda) which flows through this region not far from Friedberg.
The Wetterau Museum documents the archeology and history of the region through well-organized exhibits (in German only) on two floors. The emphasis is on agricultural history. They point out, for instance, that until around 1830 there was a large rural proletariat in this region, workers with no land of their own who were hired by the day to help with the harvest, and they had to bring their own scythe or sickle. How they survived the rest of the year is a mystery.
The existence of the large reserve army of cheap labor meant that the landowners had little or no motivation to modernize their operations, but that changed in the course of the nineteenth century as the laborers started emigrating to America in search of a better life. Eventually there was a labor shortage which forced the landowners to invest in better tools and machinery.
A plow might seem to be just a plow (or a plough, in British English), but actually there were different shapes and forms of plows, and these kept evolving throughout the nineteenth century as landowners found themselves confronted for the first time with a labor shortage.
On display in the Wetterau Museum is one of the first tractors from the early twentieth century.
On the upper floor of the museum there is a reconstruction of a general store as it looked in Friedberg around the year 1900.
As a part of its exhibits on life in this area in the 20th century, the museum has some photos of Elvis Presley, who was stationed in Friedberg as an American soldier from 1958 to 1960.
