This article examines how the annexation of Austrian (East) Galicia emerged as a distinct political—and ultimately military—mission in St. Petersburg before the First World War. The Russian nationalist project to recover the “lost lands of Rus΄ became an extension of the domestic agenda formulated by Peter Stolypin to promote Russian political and cultural hegemony in the western provinces of the empire. The campaign to liberate Subjugated Rus΄ and defeat “Ukrainian separatism” in Galicia led St. Petersburg to become ever more deeply engaged in the complex borderland politics of the Habsburg empire in the years before the war. By 1914, the idea of Subjugated Rus΄ and “four million persecuted Russians” came to inform the whole of St. Petersburg's understanding of its relations with Vienna and created an expectation that war with Austria-Hungary was inevitable.
