ウクライナの歴史
During the period of Polish ascendency, Krypiakevych co-authored and published many popularizations, the most important of which were his "Great History of Ukraine" (1935), his "History of the Ukrainian Army" (1936), and his "History of Ukrainian Culture" (1937). His textbooks of Ukrainian history were widely used both in Galicia and also among Ukrainians in North America. At this time, he also prepared a new scholarly "History of Ukraine" which was only published in 1949 in the west under the pseudonym 'Ivan Kholmsky'.
