The Massacre of the Slavníks was an act of violence during which Bohemian nobles of Boleslaus II, Duke of Bohemia slaughtered the members of the competing Slavník dynasty in Libice on 28 September 995. Only Soběslav, Adalbert, and their stepbrother Radim survived. According to older sources, this act was considered to be the event that brought about the founding of the Duchy of Bohemia. Other similar instances are reported during this same period of foundation, but no archaeological evidence of them exists.
