The wiki mentions that the Rhodoki are based on the northern italians and swiss most likely because the whole "Rhodoki rebellion pushing away the Swadians" story is a reference towards the historical events revolving around Frederick I Barbarossa, emperor of the Holy Roman Empire, attempting several times to impose his will on the italian commonalities, principalities, republics and petty kingdoms and thus gain legitimacy in his claim to be "emperor of Rome". He was once crowned by the Pope as emperor of Rome and thus of the HRE, but the rest of the italian petty kingdoms saw him more as a foreigner than a legitimate ruler and after several expeditions towards Italy he'll be eventually pushed out of the southern Alps by the Lombard League.Interestingly enough, the Wikipedia page on Frederick I mentions that, before acquiring his others titles of rulership over the other german kingdoms and, eventually, the crown and title of Holy Roman Emperor, he was to inherit the crown of Swabia, which is where Warband's Swadians take inspiration from. In that sense, Swadians and Rhodoks are the mirrors of two historical factions/entities in medieval Europe, respectively Swabia (and by extention the HRE) and the Lombard League (which has been extended into the whole of the alpine italian and swiss states).
