I remember reading that both Anglo-Saxon fyrd and Merovingian (or possibly early Carolingian?) military organization were actually more similar to Byzantine thematic system than to later feudal system of vassalage. Does anyone know books or even just historiographical works / master theses which adress this question (including how it developed and what were its political implications)? I am currently brainstorming some early ideas for story, and this question will have significant impact on how story will develop.
There were the Romans, perfect order. Then there was chaos and tribal warfare (see the Vikings, for instance). Then there was order restored in Roman's image: feudal. During the post-Roman chaos, there were many styles of tribal warfare. You could read about the people/s that sound more similar to what you're trying to depict.
Actually, from information I have found, at least Merovingian France had professional or somewhat professional army. And Anglo-Saxon fyrd was also much more closer to actual professional models (e.g. Byzantine themes) than it was to later feudal model. That is what caught my eye in the first place.
Probably more convoluted than you want to get into, but have you considered calling the local university's history department? Or a university in the region you're interested in? Assuming you can get past the language barrier, you may find that some of the professors have written books on this topic or at least lectured on it. The other option is a museum. Those are probably the two best places to look for something this obscure and specific. I'm not sure how helpful a Google search is for something this specific because this type of work is normally unknown outside of academia in my experience. Google searches show you the most popular hits in that search and something obscure may never show up, not because it isn't there but because nobody has ever searched for it.
this is getting a bit silly now, this is the sixth time you've asked essentially the same or very smiliar questions As has been pointed out before research means going out and finding documents about the things you need to know either on the internet or in real world setting like universities and libraries... you should not depend on members of this forum doing your searches for you then arguing with them when they do try to help - enough is enough https://www.writingforums.org/threads/municipal-government.166356/#post-1867889 https://www.writingforums.org/threads/basic-army-organization-and-unit-names.165829/#post-1855466s https://www.writingforums.org/threads/social-consequences-of-reconquest.166046/#post-1860584 https://www.writingforums.org/threads/amount-of-cavalry-in-flatland-armies-in-15th-century.165721/#p https://www.writingforums.org/threads/political-organization.165698/#post-1851238ost-1851657
