The article is devoted to the study of the development and main trends of modern Ukrainian historiography of the Polish-Ukrainian Alliance of 1920. The source base of the study are monographs, articles, and dissertations of Ukrainian historians in the period from 1991 to 2022. The methodological basis of the study is the principles of the Cambridge School of Intellectual History, which can be generally characterized as a contextualist method of interpretation, which places the main emphasis on historical conditions and the intellectual context of the discourse of a given historical era. These principles are especially relevant for the mentioned issue given its political sensitivity, which has not disappeared to this day. As a result, the political context at the time of the creation of the text can significantly influence the research questions and interpretations of the researchers. The author notes that since Ukraine regained its independence in 1991, Ukrainian scholars have rejected the Soviet paradigm of the history of the Polish-Soviet war and have largely adopted the interpretive schemes of emigration historiography. In this narrative, in contrast to the Soviet one, S. Petliura, when signing the agreement with Poland, was guided by Ukrainian national interests. However, Ukraine became a hostage to the selfish interests of Poland, which eventually betrayed its ally. However, as the author proves, the interpretive model that depicts the Polish-Ukrainian Alliance as the resultant force of Polish and Ukrainian interests and resources is beginning to dominate Ukrainian historiography. The aspect of uniting for the common struggle against Bolshevism began to come to the fore. A significant role in this process is played by the possibility of contacts between Ukrainian historians and Polish colleagues, the essential filling of many factual gaps and, not least, the geopolitical situation of Ukraine.
