In some examples where a political party has been dominated by a single charismatic leader, the latter's death has served to unite and strengthen the party, as with Argentina's Justicialist Party after Juan Perón's death in 1974, or the United Socialist Party of Venezuela after Chávez's death in 2013. In other cases, a populist party has seen one strong centralising leader replace another, as when Marine Le Pen replaced her father Jean-Marie as the leader of the National Front in 2011, or when Heinz-Christian Strache took over from Haider as chair of the Freedom Party of Austria in 2005.
