"Saint Peter, Metropolitan of Kiev and all Russia (Russian: Пётр)(c. 1260- 20 December 1326) was the Russian metropolitan who moved his see from Vladimir to Moscow in 1325. Later he was proclaimed a patron saint of Moscow. In spite of the move, the office remained officially entitled "Metropolitan of Kiev and All Rus'" until the autocephalous election of Saint Jonah of Moscow in 1448." - (en.wikipedia.org 02.01.2021)
