Metropolitan Peter (Petro) Mohyla (Mogila; Ukrainian: , Russian: , Romanian: ; secular name Pyotr Simeonovich Mogila, Russian: , Ukrainian: ; 21 December 1596 – 22 December 1646) was a Metropolitan of Kyiv, Halych and All-Rus' from 1633 until his death. He was born into a Moldavian boyar family — the Movilesti — one that gave Moldavia and Wallachia several rulers, including his father, Ieremia Movila. His mother, Margareta, was a Hungarian noble lady. From his early childhood, Petro Mohyla and his mother were on the move in foreign lands seeking refuge due to instability in Wallachia (part of modern-day Romania). For a time, they lived in Kamianets-Podilskyi in Ukraine. But in 1608 they moved to Poland and for sixteen years stayed in Stanislaw Zólkiewski’s (Stanislaw Zólkiewski) castle. There he started his formal schooling, which, prior to the arrival to the castle, was often interrupted by frequent moves. Petro’s teachers were monks from the Lviv brotherhood and later, he continued his studies of classical literature in Latin, Greek, Polish, and Ukrainian languages at the academy in Zamosc (Akademia Zamojska) which was founded by Jan Zamoyski. Later Mohyla continued his studies in Paris.
