sentences:  Unlike many other students of Hrushevsky, Krypiakevych never politically or intellectually rebelled against the authority of his mentor, Mykhailo Hrushevsky.Although he did turn away from Hrushevsky's populism to a pro-state interpretation of Ukrainian history, he revered his mentor's memory and in 1935 published a short biography of him.The 1939 fall of the Polish Republic and the Soviet annexation of Galicia brought far-reaching changes to academic as well as social and political life and Krypiakevych was appointed professor of history at the reorganized and partially Sovietized Lviv University.
