The (at least nominal) executives of Novgorod were always the Princes of Novgorod, invited by Novgorodians from the neighboring states, even though their power waned in the 13th and early 14th centuries. It is unclear if the archbishop of Novgorod was the real head of state or chief executive of the Novgorod Republic, but in any case he remained an important town official. In addition to overseeing the church in Novgorod, he headed embassies, oversaw certain court cases of a secular nature, and carried out other secular tasks. However, the archbishops appear to have worked with the boyars to reach a consensus and almost never acted alone. The archbishop was not appointed, but elected by Novgorodians, and approved by the Metropolitan bishop of Russia. The archbishops were probably the richest single land-owners in Novgorod, and they also made money off court fees, fees for the use of weights and measures in the marketplace, and through other means.
