Rally 'Round the Prime Minister: a study into the effects of a diplomatic conflict on public opinion under coalition government

The rally ‘round the flag effect is a well-known phenomenon in the nexus between public opinion and international relations. This phenomenon has been well studied for the US. It has not been studied extensively for multiparty coalition systems. This study analyses the effect of a diplomatic crisis on the popularity of the Prime Minister of the Netherlands. It makes three key contributions to the literature on the rally effect. Firstly, it considers the effect of a diplomatic incident on the popularity of the head of government in a parliamentary system with coalition government. Secondly, it considers the effect of this incident on both the Prime Minister and the Vice Prime Minister who come from different parties. Thirdly, it employs a matching quasi-experimental design to get a better grip on the causal relationship between an international conflict and the support for government leaders.
