And Ukrainians evicted the Poles and moved into Western Ukraine...S.O.P. in that part of the world for centuries.
My mother's parents came to the US in 1905 from near Lvov. They were devout Russian Orthodox and did not feel safe because of Poles taking over. When they came here, they settled in CT and there are records from their Church that the Czar sent money to help them found and sustain that church.
Has the Ukraine ever had peace and prosperity for long?
