1. i hate this toxic introduction bs
2. bother me with details I asked for?
3. You dont know the situation of bohemia and its not ideal? How are you so sure about the non-tribalism then?
4. "In 845 Bohmians had multiple princes/chiefs?" you mean like tribal heads?
5. undisputed souvereign of Bohemia? im pretty sure slavnikids competed with them for the control - the reason why they got slaughtered
6. "for Svatopluk of Moravia it was enough to vasalise Bořivoj to become the overlord of Bohemia." This is true because the others were still dependent on the centre of power - prague. plus the next thing you said
7. its county tier vassals are not tribal. everything is feudal.
8. "Btw the Slavníkids got their areas of influence from Přemyslids as their faithfull allies" source please. Spytihněv I. and Vitislav (Slavniks grandfather) were both invited on eye level to meet King Arnulf in Regensburg.
9. The tribes were not invented by some troll. It was a thing. except maybe Záhvozd, Tuhošť and moravia which are rather regions
I am very sorry about the sound. It is really hard to not sound like that. It's very annoying when you base your knowledge on academic resources from the best historians and somebody puts some pic from the internet and tells you you're wrong because this proves it.
You ask for details, yet you obviously don't know the basics, like that who and under what conditions have murdered the Slavníkids. That said, I don't have the time to rewrite 3 400+ pages books here.
Maybe you can read them?
Počátky Přemyslovců and Vznik Velké Moravy by Dušan Třeštík and
Čechy v době knížecí by Josef Žemlička.
These are 2 of the most respected modern experts about Bohemian medieval history, not some random guys writing wikipedia or internet experts.
Yet, let's share some details with you:
Slavníkids were dependent on Přemyslids to get to power. Later on they rose among the most prominent families and became very influential so they indeed were given audiences by powerfull German princes and kings. This happened intime when Přemyslid ruler, Boleslav II. was in bad health btw.
They were murdered against the will of Boleslav II. by Vršovci family, not at Bileslav's orders as some older historians assumed. It is pretty well known among anybody who knows any details about early medieval Bohemia, no matter what English wikipedia may write about them. Should I write more? Well, I don't think I'm here to educate anybody who just reads wrong hiatory sources.
Bohemian princes vs.tribal princes? They were all referred as Bohemians, not Zličans etc. There is no doubt about Bohemians being dispersed across the country with regional leaders. Those can be referred as some clan or even tribe, but let's talk about what do you understand as tribe then.
Tribe as a unit of political integration etc... but let's talk about it some other time
