Legitimacy communication in the media reveals when elites become attentive to international organizations’ (IOs) legitimacy and whether they support or question their legitimacy. The intensity and tone of this communication results in communicative support or legitimacy pressures on IOs. Extant research gives few insights into the scope and nature of elite legitimacy communication and the factors that shape it. This article offers a comparative and longitudinal analysis of the patterns of elite communication in the media. It maps and explains variation in the intensity and tone of legitimacy communication based on a quantitative content analysis of roughly 6500 legitimacy evaluations of the EU, the G8, and the UN in the quality press of four established democracies. A multinomial logistic regression analysis yields three key results. First, in contrast to conventional expectations, there is no clear shift from low intensity and positive tone to high intensity and negative tone. Second, communication intensity is considerably higher for powerful IOs. Third, political events, including security crises and institutional reform, are important drivers of the ebbs and flows of western elites’ communicative support and pressure on major IOs.
