During the 2015 migration wave, Hungary was a transit, rather than a target, country for migrants fleeing from North Africa and the Middle East to Europe. In reaction to this, Viktor Orbán’s right-wing populist government built a wall on the country’s southern border and launched an anti-migration communication campaign, portraying itself as the saviour of European, Hungarian and Christian values. This article reconstructs the messages and effects of this campaign. It finds that in a context of limited political and media pluralism, an anti-migration campaign may exert a significant impact on public opinion and political behaviour.
