Władysław Siemaszko

Definition
Władysław Siemaszko is a Polish historian and author noted for his research on the ethnic conflicts and massacres that occurred in Volhynia and other Eastern Borderlands of Poland during World War II.

Overview
Siemaszko has contributed to the documentation and analysis of the violence perpetrated against the Polish civilian population by Ukrainian nationalist groups, particularly the Ukrainian Insurgent Army (UPA), between 1943 and 1945. His work is frequently cited in scholarly discussions of Polish‑Ukrainian relations, the historiography of World War II in Eastern Europe, and the broader study of ethnic cleansing and genocide. Siemaszko’s publications often combine archival research with testimonies from survivors, many of whom were his own relatives or acquaintances.

Etymology/Origin
The name Władysław is a traditional Polish given name derived from the Old Slavic elements vladeti (“to rule”) and slav (“glory”). Siemaszko is a Polish surname, likely originating from a patronymic form of the given name Szymon or from a regional variant of Szymanski. The surname is most common in the southeastern regions of Poland.
