Combining social, political, and economic history with great aplomb, Oil Empire greatly enriches the history of an understudied region. Frank skillfully engages the bewildering patchwork that was Galicia. Poles battled Ukrainians, Catholics persecuted Jews, agrarian nobles fought bourgeois modernizers, socialists rose and fell, German-speaking civil servants tried to lord it over everyone, and hordes of peasants emigrated to other lands. The imperial center alternately clashed with and ignored the provincial periphery. Frank has constructed a balanced narrative, a sophisticated analysis, and a very persuasive argument.
