In Jordan - home to some one million Syrian refugees - the vital roles played by vernacular politics, discourses of inclusion and exclusion, and sectarian social histories for Syrians are often considered unimportant when examining possibilities for integration or coexistence. Based on ethnographic research and participation in women's religion classes in a Syrian refugee camp in Jordan in 2014, I argue that while sectarian identities may not in and of themselves appear to divide the majority of Syrian refugees in Jordan from the majority of Jordanian residents (as Sunni Muslims), through utilizing a vernacular politics theoretical perspective I reveal that the sectarian orientations and localized histories of Syrian refugees have an understudied potential to create new forms of divisiveness in Jordanian society. To dismiss any concerns raised, Jordanians reinforce the idea that sectarian discourses, in an objectified sense, are not welcome in Jordan, and that they are even-as a few asserted-"against Islam". These differing national experiences with vernacular politics expressed in sectarian terms prompt Jordanians to reinforce the narrative that Jordan is free of such divisions, and will continue to remain so. This paper concludes by discussing the implications for national-transnational tensions.
