Populism, global crisis, and modernity have rendered citizenship an ever-more fluid and troubled concept. This conference will explore all of these themes. In the first panel, we will debate the concept of economic citizenship, asking to what extent citizenship can be bought, constituted, or even lost by means of variation in wealth. In a second panel on citizenship and its gatekeepers, our discussion will explore how states, tribes, and other communities regulate belonging. And in the third panel, we will examine how migration and cross-border identity challenge the concept of citizenship.
