In 2011, a monument commemorating a group of Polish academics killed during the Nazi occupation was unveiled at the site of their death in L΄viv, presently a Ukrainian city. This event became the pinnacle of a commemoration that had developed quite autonomously on both sides of the redrawn Polish-(Soviet)Ukrainian border. The commemorative project and memory event underpinning it are especially interesting owing to the partial recuperation of links with the prewar local genealogies of the Polish-Ukrainian borderland. This article explores how a special historic occurrence that took place in wartime L΄viv/Lwów became an issue of continual political significance invested with different truth, originality, and identity claims in Poland and Ukraine. The authors focus on various actors who managed to transform memory about the murdered academics into a public commemorative project and elevate the role of translocal links in the successful realization of the commemorative initiative in question. The concluding part summarizes principal lessons pertaining to commemoration of perished population groups in east-central European borderlands that might be drawn on the basis of the discussed case.
