The interwar period in Poland between 1919 and 1939 was punctuated by three significant crises in ethnic relations: the presidential succession of 1922, the Pilsudski coup of 1926, and the “pacification” of the Ukraine in 1930. This article is an attempt to sketch certain aspects of these crises based primarily on records of parliamentary debates. Within the walls of Parliament ethnic conflicts were aired and articulated openly. Here the claimants spoke to and with one another, rather than solely to their own particular clienteles.
The number of non-Polish inhabitants within the frontiers of post-Versailles Poland has been variously estimated at between 30 and 45 percent of the total population, depending on the source, time, and method of classification used in the estimate.
