Silvio Berlusconi has unquestionably been one of Italy’s most important political figures since the early 1990s. The general election campaign of February 2013 demonstrated that he is anything but out of the political game. Consequently, it seems worthwhile to examine Berlusconi as a prime minister and coalition leader. This article seeks to understand the extent to which he was able to command and guide his governing coalition, as Prime Minister, as well as his influence and the constraints on his actions. After presenting the theoretical framework, the article examines Berlusconi within the context of Italian political history and explores his impact on coalition governance by illustrating two cases of how he managed intra-coalition conflicts during his second term of office. Finally, it discusses the findings and highlights the resources Berlusconi was able to deploy ‘against’ his allies and the constraints he faced as Prime Minister. A brief comparison of Berlusconi and other Italian prime ministers is provided.
