I’ve wanted to find out some information about Dithmarschen’s republic for a while now, but it seems pretty hard to find, you can find information about the battle of Hemmingstedt, but information about how the republic was run, or what life was like for those living in it seems very sparse. Tldr: how was the republic of Dithmarschen run, and what was life like?
There's always more that can be said but you might like checking out this older post from /u/bemonk in How did the free peasant republic in Dithmarschen in the 15th and 16th centuries actually function?
and this answer from /u/mikedash in How accurate is Monty Python's 'Anarcho-Syndicalist Peasant' scene? Were small medieval villages de-facto self governing and autonomous from their noble lord and wider nation?
Basically your question is already answered in the other, here linked but archived threads. But since I feel some kind of misinformation in the way most english-speaking users see Dithmarschen I want to leave a comment here.
The most important misconception is probably rooted in the word "marsh".
First because the "marsch" in DithMARSCHen doesnt refer to the landscape, its just a coincidence. It actually meant something like Tetmarsgau, the land of Tetmar.
Second because the german word Marsch cant be translated to the english word marsh. Though Marsch describes a relatively wet and flat landscape, Marschen are still a very valuable agricultural region. While marsh seems to describe a more swamp-like area.
If you have other, more specific questions - ask me anything, I´m a Dithmarscher :)
Which means that I have some exclusive (but not professional historical) information - probably never written down in the Internet. For example a dispute between the "Süderdöfft" (the most southern part of Dithmarschen next to the Elbe) and the rest of Dithmarschen because this southern part earned their money with piracy of ships sailing to and from Hamburg. But the rest of Dithmarschen wanted to sell wheat to Hamburg and therefore needed to be trustworthy.
