[4][5] It is generally believed that the tribal union included the regions of Moravia, Nitravia (Nitra), Silesia, Bohemia and Lusatia.

According to Julius Bartl, the centre of the polity lay "somewhere in the area of southern Moravia, Lower Austria, and western Slovakia (Nitravia)".

Bury, "the assumption that his kingdom embraced Carantania, the country of the Alpine Slavs, rests only upon the Anonymus de conversione Bagariorum et Carantanorum".

According to Slovak historian Richard Marsina, it is unlikely that the center of Samo's tribal union was in the whole territory of present-day Slovakia.

[14] Samo went on to secure his throne by marriage into the major Wendish families, wedding at least twelve women and apparently fathering twenty-two sons and fifteen daughters.

[13] The Franks were routed near Wogastisburg; the majority of the besieging armies were slaughtered, while the rest of the troops fled, leaving weapons and other equipment lying on the ground.

In the aftermath of the Wendish victory, Samo invaded Frankish Thuringia several times and undertook looting raids there.

[17] Dervan, the "duke of the Sorbs" (dux gente Surbiorum que ex genere Sclavinorum), initially subordinate to the Franks, joined the Slavic tribal union after Samo defeated Dagobert I.

[15] Ultimately, Samo can be credited with forging a Wendish identity by speaking on behalf of the community which recognised his authority.
