Medieval chronicler
Helmold of Bosau described the Rani as the only
Wendish tribe ruled by a king and reports them as having subdued many other tribes, while not tolerating subordinance themselves. Common decisions of the Wendish tribes were made only with the approval of the Rani. The highest-ranking position was in fact that of the High Priest, who stood above the king. The oracle decided whether and where campaigns were to be mounted, and after a victory the money and precious metals of any bounty were given to the temple before the rest was partitioned. Subdued tribes were made subordinate to the temple. The Rani political capital was
Charenza (then Korenitza, today an unsettled site called
Venzer Burgwall). Rani dukes also resided at
Rugard castle, a precursor of the modern city of
Bergen. Throughout the Rani lands there were castles (
burghs), all having a ring-like wall of wood and clay, protecting villages and/or religious sites, and functioned as strategic strongholds or seats of the gentry. The Rani also established a main, mixed Slavic and Viking, trading center in
Ralswiek. In the 11th and 12th centuries, they also conducted Viking-style raids on their neighbors. ==Language==
