On December 22, 2017 the Ukrainian Diplomatic Service marked the 100thanniversary of its establishment and development. In dedication to such a momentous event, the Department of International Relations of Yuriy Fedkovych Chernivtsi National University has published a book of IR Dept’s ardent activity since its establishment. It includes information both in Ukrainian and English on the backbone of the collective and their versatile activities, achievements and prospects for the future.
 The author delves into retracing the course of the history of Ukrainian Diplomacy formation and development. The author highlights the roots of its formation, reconsidering a long way of its development that coincided with the formation of basic elements of Ukrainian statehood that came into existence as a result of the war of national liberation – the Ukrainian Central Rada (the Central Council of Ukraine). Later, the Ukrainian or so-called State the Hetmanate was under study. The Directorat (Directory) of Ukraine, being a provisional collegiate revolutionary state committee of the Ukrainian People’s Republic, was given a thorough study. Of particular interest for the research are diplomatic activities of the West Ukrainian People`s Republic. Noteworthy, the author emphasizes on the Ukrainian Socialist Soviet Republic’s foreign policy, forced by the Bolshevist Russia.
 A further important implication is both the challenges of the Ukrainian statehood establishing and Ukraine’s functioning as a state, first and foremost, stemmed from the immaturity and conscience-unawareness of the Ukrainian society, that, ultimately, has led to the fact, that throughout the twentieth century Ukraine as a statehood, being incorporated into the Soviet Union, could hardly be recognized as a sovereign state.
 Our research suggests that since the beginning of the Ukrainian Diplomacy establishment and its further evolution, it used to be unprecedentedly fabricated and forged.
 On a wider level, the research is devoted to centennial fight of Ukraine against Russian violence and aggression since the WWI, when in 1917 the Russian Bolsheviks, headed by Lenin, started real Russian war against Ukraine. Apropos, in the about-a-year-negotiation run, Ukraine, eventually, failed to become sovereign. Remarkably, Ukraine finally gained its independence just in late twentieth century. Nowadays, Russia still regards Ukraine as a part of its own strategic orbit,waging out a carrot-and-stick battle.
