Scholars of the Ukrainian-Ruthenian lands of the Habsburg monarchy have always faced a multiplicity of political and administrative-territorial jurisdictions. Until 1918 those lands constituted parts of three distinct administrative-territorial entities: the eastern half of Galicia-Lodomeria; a sliver of northeastern Hungary, embracing part or all of the Transcarpathian counties Bereg, Máramaros, Szatmár, Ugocsa, and Ungvár; and the northern half of Bukovina. Those divisions more or less survived the monarchy's collapse, with the regions being divided between Poland (Galicia), Czechoslovakia (most of Transcarpathia), and Romania (Bukovina, plus Máramaros). Eastern Galicia, for example, was known in Poland as Eastern Little Poland (Małopolska Wshodnia), while Ukrainian nationalists called it Western Ukraine, and even Soviet authorities also used that latter designation during the interwar period, implying that the territories should be joined to the rest of Ukraine, as part of the larger Soviet “Fatherland.”
The archival records of the Habsburg monarchy that remained in those three areas accordingly became subject of the differing recordkeeping and archival practices of the successor political regimes. Polish authorities established a State Archive in Lviv (Polish, Lwów) (Archiwum Państwowe we Lwowie), as part of the Polish archival system, and the principal records of the Austrian period in Eastern Galicia were concentrated there. Through a series of postwar archival claims, some major groups of records of Austrian rule in Galicia-Lodomeria that remained in Vienna were transferred to Polish authorities. These, for the most part, were deposited in Warsaw, where those that survived World War II remain today in the Main Archive of Early Acts (Archiwum Główne Akt Dawnych—AGAD).
