Using Peter Merriman's recent book as a trigger, this review-cum-polemic argues that mobility history is facing a scholarly crisis in the midst of other mobility-related fields that are blossoming. The core of the diagnosis is a lack of debate on a central question that is painfully missing. The article suggests as a remedy the opening up of the field along the paths of transmodality, transdisciplinarity, and especially transnationality. The national bias of much historical scholarship is a hindrance to its future blooming.
