Maximos, Metropolitan of Kiev

Maximus or Maximos was a metropolitan bishop of the Metropolis of Kiev and all Rus' in the Ecumenical Patriarchate of Constantinople. He was consecrated in Constantinople and reigned from 1283 to 1305. Maximos was of Greek origin.
At that time, the Rus' princes were vassals of the Golden Horde. Khan Tokhta wanted to eliminate the princes' semi-independence. To that effect, he had sent his brother Tudan to the Rus' lands in 1293. Tudan's army devastated fourteen towns. Tokhta himself went to Tver and forced Dmitry of Pereslavl, who was allied to Nogai Khan, to abdicate. Rus' chronicles depicted these events as "The harsh-time of Batu returns.". Some sources suggest that Tokhta and Nogai, who was effectively the co-emperor, had worked together.
Maximos was known for his ecclesiastic trips to the Golden Horde and for mediating between the quarreling princes of the north-eastern Rus'. Under instructions from the Khan, Maximus left Kiev in 1299 and transferred the metropolitan chair to the city of Vladimir on the Klyazma which is situated east of Moscow. Following that, Patriarch Athanasius I of Constantinople established the Metropolis of Halych in 1303 with its see in Halych in the Kingdom of Galicia–Volhynia.
In 1301, Maximos attended a patriarchal council in Constantinople. He supported the Prince of Tver and Vladimir Mikhail Yaroslavich in his struggle with Prince of Moscow Yuri Danilovich for the title of Grand Prince of Vladimir.
He was canonised a saint in the Russian Orthodox Church, and his feast day is celebrated on December 6.
