There are no dates in this genealogy, but some can be extrapolated. The first archon arrived during the 610-626 period, and died (long time?) before the Bulgar invasion which occurred in 680. Historian Konstantin Jireček in his "History of the Serbs I", page 69, estimates the rule of Višeslav, the first Serbian ruler whose name is known, around 780. One of his two successors was in power in 822, as mentioned in the "Royal Frankish Annals". The work deals with an episode concerning the Pannonian ruler Ljudevit Posavski. Under the Frankish attack he left his capital Sisak and fled over to the Serbs, for which is "said to be as holding the large part of (Roman) Dalmatia": "Siscia civitate relicta, ad Sorabos, quae natio magnam Dalmatiae partem obtinere dicitur, fugiendo se contulit". However, the mentioning of "Dalmatia" in 822 and 833 as an old geographical term by the authors of Frankish Annals was "Pars pro toto" with a vague perception of what this geographical term actually referred to. In the contemporary "Vita Hludovici" that description of the Serbs is omitted. Ljudevit later killed the local župan who took him in and temporarily took over the rule in his župa, which is estimated to be either somewhere in western, central or eastern Bosnia. Some historians pointed to the modern village of Srb in the region of Lika in modern Croatia, as the possible location as in the medieval period it was a town, described in the early 14th century as having "Serbian seat and court, like in the old times". Frankish chronicle makes a distinctions between the settlements ruled by the Croats (referring to them as "castellis", or castles) and those held by the Serbs ("civitas", or city-states). Ljudevit then fled to the Croatian domain, but was soon murdered. During the 822 uprising, Serbs supported the rebellion, thus siding against the Frankish Empire and indirectly supporting the Byzantines, but it is unknown to which extent they participated in the skirmished between two empires in the 8th and the 9th century.
