Overview
Simeon Ivanovich (; 7 September 1317 – 27 April 1353), also known as Semyon Ivanovich, nicknamed the Proud, was Prince of Moscow and Grand Prince of Vladimir from 1340 to 1353.
The son of Ivan I, Simeon continued his father's policies aimed to increase the power and prestige of his state. Simeon's rule was marked by regular military and political standoffs against the Novgorod Republic and the Grand Duchy of Lithuania. His relationships with neighboring Russian principalities remained peaceful if not passive: Simeon stayed aside from conflicts between subordinate princes. He had recourse to war only when war was unavoidable. A relatively quiet period for Moscow was ended by the Black Death that claimed the lives of Simeon and his sons in 1353.
Biography
In 1340 Simeon, the eldest son of Ivan Kalita, was stationed in Nizhny Novgorod. Upon receiving news of his father's death, Simeon and his brothers Andrey and Ivan left for the Golden Horde to seek Uzbeg Khan's patent (yarlyk) for taking over the title of Grand Prince. Rivals Konstantin of Tver and Konstantin of Suzdal also paid their homage to the Khan, claiming seniority over Moscow princes. Simeon won the patent through bribing the Khan's retinue; princes of Tver and Suzdal had to agree to his seniority; Uzbeq also extended his benevolence to Simeon's issue. He was also granted the ceremonial title by the Byzantine Empire, which can be loosely translated as seneschal or stolnik.
Also in 1340, Simeon engaged in his first military standoff with Veliky Novgorod. Simeon claimed his right to collect taxes in the Novgorodian town of Torzhok. Torzhok boyars locked up Simeon's tax collectors and called for help from Novgorod. Simeon and metropolitan Theognostus hastily organized a coalition of princes against Novgorod, claiming that "They [Novgorodians] make war and peace with whomever they please, consulting no one. Novgorod regards not all Russia, and will not obey her Grand Prince", referring to Novgorod incursions into Ustyuzhna and Beloe Ozero. As the coalition forces approached Novgorodian lands, the people of Torzhok revolted against the boyars and sided with Muscovite troops. Novgorod Republic accepted the fact and ceded all taxes from Torzhok area, estimated at 1,000 roubles in silver annually, to Simeon who agreed to honor the existing civic charter.
