But by late 11th century, Novgorodian assembly began the process of selection their own princes.
Novgorod was under Prince Vsevolod Mstislavich until uprising of the boyars of Novgorod in 1136 put an end of the effective rule of the prince. From that time on, the prince held only nominal power a sort of viceroy for the grand prince of Kiev.
In May of that year, the Novgorodians arrested Vsevolod, imprisoned him in the bishop’s palace, and established new conditions for their princes.
During 1136 to 1240, for all practical purposes was an autonomous merchant republic within the loosely organized federation of Russian principalities the Kievan state, only formally acknowledging the suzerainty of the grand price of Kiev.
Ivan III defeated Novgorod in 1471 and reasserted the provisions of the treaty of Iazhelbitsy, Finally, in 1478 Ivan annexed Novgorod and took down the assembly bell and brought it and much treasure to Moscow.
