According to Professor Marek Jan Chodakiewicz, Per Anders Rudling’s The Rise and Fall of Belarusian Nationalism, 1906-1931 (Pittsburgh, PA: University of Pittsburgh Press, 2015) is seriously flawed both as far as its intellectual framework and understanding of subtle nature of the identity of the people inhabiting Belorussian lands. More in-depth research and less analytical bias stripped of leftist ideological prejudice should fix the problem.
