In the former [[Polish–Lithuanian Commonwealth|Polish-Lithuanian Commonwealth]], the titles of prince dated either to the times before the [[Union of Lublin]] or were granted to Polish nobles by foreign monarchs, as the law in Poland forbade the king from dividing nobility by granting them [[hereditary title]]s: see [[The Princely Houses of Poland]].{{citation needed|date=November 2016}}

In Ukraine, landlords and rulers of [[Kievan Rus']] were called князь (''[[Knyaz|knjazʹ]]''), translated as "prince". Similarly, foreign titles of "prince" were translated as ''knyaz'' in Ukrainian (e. g. [[Ivan Mazepa]], "knyaz of Holy Roman Empire"). Princes of [[Rurik Dynasty]] obeyed their oldest brother, who was taking the title of [[Grand Prince of Kiev]].<ref>{{cite journal |last=Kollmann |first=Nancy Shields |authorlink=Nancy Shields Kollmann |title=Collateral Succession in Kievan Rus |journal=Harvard Ukrainian Studies |year=1990 |volume=14 |pages=377–387}}</ref> In 14th their ruling role was taken by Lithuanian princes, which used the title of Grand Prince of Lithuania and Ruthenia.<ref>Between Two Worlds: A Comparative Study of the Representations of Pagan Lithuania in the Chronicles of the Teutonic Order and Rus'</ref> With the rise of cossacks, many former Ukrainian princes were incorporated into the new [[Cossack nobility]].{{citation needed|date=November 2016}}

In the Russian system, ''knyaz was'' the highest degree of official nobility. Members of older dynasties, whose realms were eventually annexed to the [[Russian Empire]], were also accorded the title of ''{{Lang|ru-Latn|knyazʹ}}''—sometimes after first being allowed to use the higher title of [[tsarevich]] (e.g. the Princes [[Gruzinsky]] and [[Sibirsky (surname)|Sibirsky]]).{{citation needed|date=November 2016}}
