Abstract
Any success of a populist party is often considered as a threat, a rise endangering Democracy. Even if there is a lot of passion over this issue, it is true that there has been a rise of populist parties in Europe, from the 1980s to late 1990s, a rise which has stabilized or reversed recently. These new populist parties appeared after the great period of stability (from the post war to the late 1960s), a period in which most extremist parties were small groups or party flashes. Since then, there are new populist parties. It is funded on a direct link between the leader and the people and a distinction between 'us' and 'them'.
