 An increasingly important challenge to the institutionalist paradigm of global justice is the historical legacy and contemporary effects of colonialism. The idea that our obligations of distributive justice as determined by our current institutions might be undermined by the idea that the historical relationship of colonialism has tremendous influence on current distributions of wealth and power. The focus on colonialism has three aspects though this section will focus mostly on the second and third. First, there is a growing interest in whether the early modern progenitors of the social contract tradition were ideologically complicit in European imperialism. In particular, there is a lively debate concerning how Kant’s account of hospitality and cosmopolitan right can used to critique colonial and neo-colonial relations (Flikschuh &amp; Ypi 2014). Second, there is a significant—and mostly cosmopolitan in orientation—debate concerning precisely what makes colonialism unjust or wrong. Third, given the wrong of colonialism and the likely reverberation of its negative effects onto the present, there is the question of rectificatory global justice. That is, colonial powers have some distributive duties in virtue of the fact that they must repair the harm caused by their imperial endeavors.
