While some scholars accept at face value the democratic principles claimed by Piłsudski for his federative plan, others view such claims with skepticism, pointing out a coup d'état in 1926 when Piłsudski assumed nearly dictatorial powers. In particular, his project is viewed unfavorably by most Ukrainian historians, with Oleksandr Derhachov arguing that the federation would have created a greater Poland in which the interests of non-Poles, especially Ukrainians, would have received short shrift.
