While mobilities research is cognisant of the need to theorise the politics of mobility, the extent to which a political theory of movement has been developed is debateable. In this paper, I develop a more substantive theorisation of movement as a constitutive political relation in light of the empirical advances generated by mobilities research. This account of kinetic politics is an important conceptual development that holds promise for the closer alignment of mobilities research with critical security studies, which in turn raises the possibility of a fuller understanding of movement in global politics.
