ABSTRACT
The eighteenth-century Partitions of the Polish-Lithuanian Commonwealth had placed the far west of the Ukrainian lands under Austro-Hungarian rule, as the province of Galicia, but most became part of imperial Russia. It was Polish historians in the late nineteenth and early twentieth century who largely contributed to the rejection of the 'Jagiellonian myth' by Ukrainian historiography. The first Polish-Lithuanian Union, concluded in Krevo in 1385, was one of the most important events in the history of Eastern Europe, and Ukrainian historians could not avoid it in their assessments. The Jagiellonian era in Ukrainian history is also associated with attempts to implement a Church union between the Latin and Orthodox Churches, which culminated in the Union of Brest in 1596 after the end of the dynasty. However, the Union was not achieved in a single day, and members of the Jagiellonian dynasty were in one way or another engaged in the matter.
