For approaches that focus on the historical impact of locality or regionality, see for instance Philipp Ther and Holm Sundhaussen, eds., Regionale Bewegungen und Regionalismen in europäischen Zwischenräumen seit der Mitte des 19. Jahrhunderts (Marburg, 2003); Beth Mitchneck, “Geography Matters: Discerning the Importance of Local Context,” Slavic Review 63, no. 3 (Fall 2005): 491–516; Christophe Duhamelle, Andreas Kossert and Bernhard Struck, eds., Grenzregionen. Ein europäischer Vergleich vom 18. bis zum 20.

Nationalisierung, Nivellierung und Sowjetisierung einer mitteleuropäischen Stadt, 1919–1991 (Wiesbaden, 2010); Gregor Thum, Uprooted: How Breslau Became Wrocław during the Century of Expulsions (Princeton, 2011); and Christoph Mick, Lemberg, Lwów, L΄viv, 1914—1947: Violence and Ethnicity in a Contested City (West Lafayette, 2016).
