The prince, while his status in Novgorod was not inheritable and his power was much reduced, remained an important figure in Novgorodian life. Of around 100 princes of Novgorod, many, if not most, were invited in or dismissed by the Novgorodians. At least some of them signed a contract called a "r'ad" (ряд), which protected the interests of the Novgorodian boyars and laid out the prince's rights and responsibilities. The r'ads that have been preserved in archives describe the relationship of Novgorod with twelve invited Princes: five of them from Tver', four from Moscow, and three from Lithuania.
