With only a few exceptions, previous studies on terror attacks and election outcomes have focused on a particular country or attack, limiting their generalizability. We use data on 393 legislative elections held in 39 European countries during the period 1970–2017 to estimate the effects of terror attacks on election outcomes. Terror attacks occurring shortly before an election are associated with an increase in an index of nationalist vote share.
