Alexius, Metropolitan of Kiev

Alexius (Russian: Алексий, Aleksii; before 1296–1378)[1] was Metropolitan of Kiev and all Rus' (from 1354) and presided over the Moscow government during Dmitrii Donskoi's minority.

When Dmitry Donskoy and Vladimir the Bold were young, Alexius was their spiritual tutor and served as regent at the same time.

He took the side of Dmitrii Donskoi in his struggle against Tver and Nizhny Novgorod, where he once sent Sergius of Radonezh to suspend service in churches and monasteries, until the political strife was over.

In 1357, Alexius was summoned by Jani Beg, the Khan of the Golden Horde, to cure his mother Taydula Khatun of blindness.

[4] The 2012 film The Horde is a highly fictionalised narrative of how Alexius healed Taidula from blindness.
