Prince of Novgorod

The Prince of Novgorod (Russian: Князь новгородский, knyaz novgorodskii) was the chief executive of Novgorod the Great. The office was originally an appointed one until the late eleventh or early twelfth century, then became something of an elective one until the fourteenth century, after which the Prince of Vladimir (who was almost always the Prince of Moscow) was almost invariably the Prince of Novgorod as well.

The office began sometime in the ninth century when, according to tradition, the Viking (Varangian) Riurik and his brothers were invited to rule over the Eastern Slavs, but real reliable information on the office dates only to the late tenth century when Vladimir the Great was prince of Novgorod. The office or title technically continued up until the abdication of Nicholas II in 1917 – among one of his titles (although his list of titles was rarely given in complete form) was Prince of Novgorod the Great.

After the chief Rurikid prince moved to Kiev in the late ninth century, he usually sent either his son or a posadnik (mayor), to rule on his behalf. Thus Sviatoslav I sent his son Vladimir the Great to rule in Novgorod, and after Vladimir became Grand Prince of Kiev, he sent his son, Yaroslav the Wise to reign in Novgorod.

From the early twelfth century to 1478, the prince's power in the Republic of Novgorod was more nominal. Imperial and Soviet-era scholars often argued that the office was ineffectual after 1136, when Prince Vsevolod Mstislavich was dismissed by the Novgorodians, and that Novgorod could invite and dismiss its princes at will. In this way, the prince of Novgorod was no longer "ruler" of Novgorod but became an elective or appointed executive official of the city-state.
