The Grand Duchy of Lithuania was one of the largest and most linguistically, ethnically and religiously diverse polities in late medieval and early modern Europe. In the mid-1380s the Grand Duchy of Lithuania entered into a long process of union with the Kingdom of Poland. Since the destruction of the Polish-Lithuanian Commonwealth in 1795, the history and memory of the Grand Duchy of Lithuania have been much contested among its successor nations. This volume aims to excavate a level below their largely incompatible narratives. Instead, in an encounter with freshly discovered or long neglected sources, the authors of this book seek new understanding of the Grand Duchy, its citizens and inhabitants in "microhistories." Emphasizing urban and rural spaces, families, communities, networks, and travels, this book presents fresh research by established and emerging scholars.
