Assassination of Paweł Adamowicz
Paweł Adamowicz, the mayor of Gdańsk, Poland, was fatally stabbed on 13 January 2019 while onstage during a local public event marking the 27th finale of the Great Orchestra of Christmas Charity, a nationwide Polish charity fundraiser, which was taking place in the city's Targ Węglowy square. The attacker, a spectator named Stefan Wilmont, entered the stage without obstruction and, following the stabbing, made a statement into a microphone citing Adamowicz's political affiliation as a motivation for the act.
