Українська козацька держава і її творець Богдан Хмельницький

The book includes four scientific investigations by the most prominent Galician historian Ivan Krypyakevich (1886–1967) - "Studies on the state of Bohdan Khmelnytskyi", "To the history of the State Archive of the 17th century", "State treasure under Bohdan Khmelnytskyi" and "Serbs in the Ukrainian army ". Written in the interwar period, they are an example of combining scientific objectivity with deep patriotism. The scientist rightly considered the era of Khmelnychnya to be the era of the revival of Ukrainian statehood in the difficult conditions of the war for independence. This makes the book extremely relevant and necessary in our time. It will be interesting for all Ukrainians who are concerned about the fate of our country.
