This paper examines how territorial rescaling and ensuing citizenship realignment in Europe affect marginalised minorities. It focuses on the case of Roma and calls for a new perspective on this minority: instead of viewing Roma as an exceptional non-territorial minority and migrants, it investigates their position primarily from a citizenship perspective. While examining different examples of the citizenship position of Roma, the paper argues that their positions represent the margins, which become central in defining what citizenship entails at different levels. The margins are usually not directly visible, yet they define the ‘boundaries’ of citizenship salient during episodes of territorial rescaling.
