Whilst a body of work exists that has engaged with and conceptualised transnational fields, and in particular for this paper, the transnational field of human rights, more work needs to be done to elaborate on the effects of transnational fields, at the national level. Using Bourdieu's field theory, and more recent scholarship that focuses on scalar aspects of fields, this research focuses on a human rights field at the national level in Bahrain. The paper addresses two levels/dimensions of the transnational field of human rights: the transnational level and the national level, focussing on the field's vertical autonomy. Based upon nineteen in-depth interviews, the research retrieves the biographical trajectories of Bahraini human rights activists and activists from iNGOs with a specific remit that includes Bahrain. The paper argues that the vertical autonomy of the transnational field of human rights has demonstrable field effects at the national level, and that this has a number of implications. First, where transnational fields have greater vertical autonomy, the national level can operate with varying hierarchies, with actors adopting practices that diverge from those acting transnationally. Second, as a result of these scalar differences and the vertical autonomy of the transnational field, actors at the national level may have to adapt their practices, others can be side-lined as a result of 'symbolic pollution.' Third, in order for local actors to engage with transnational advocacy networks, they must be the right type of actor.
