International organizations (IOs) have become increasingly pervasive features of the global landscape. While the implications of this development have been studied extensively, relatively little research has examined the factors that prompt states to enter IOs. We argue that democratization is an especially potent impetus to IO membership. Democratizing countries are likely to enter IOs because leaders have difficulty credibly committing to sustain liberal reforms and the consolidation of democracy. Chief executives often have an incentive to solidify their position during democratic transitions by rolling back political liberalization. Entering an IO can help leaders in transitional states credibly commit to carry out democratic reforms, especially if the organization is composed primarily of democratic members. Tests of this hypothesis, based on a new data set of IOs covering the period from 1965 to 2000, confirm that democratization spurs states to join IOs. a
