Ukraine; from about 1910 to World War II.

It seems that Ukraine rarely made the news until about 2013-14 when Russia invaded Crimea and somehow the Bidens were involved in a scandal. I knew of it, because my mother's family all trace their lineage to the Ukraine as recently as the 1920s. I do not go into any of that here - we're going back to the beginning of the 20th century, when Ukraine was a nation split between the Hapsburgs and the Romanoffs. During the first half of the 20th century, Ukraine was in the middle of everything. What was Ukraine like demographically then and now, and what is the legacy of a century of nation building?

Thanks for listening!
