Research into religion and international relations (RIR) has come incredibly far in the decades since 9/11. However, a tension remains in this research program, as neopositivist scholars simultaneously argue religion both has an independent effect on and interacts with international politics. This has raised critiques of religion’s importance. Relational work in international relations—inspired by scholars such as Bourdieu, LaTour, and Tilly—provides a means to overcome this obstacle. While some works on RIR have drawn on this tradition, it has yet to be systematized. In this review article, I discuss three recent books that highlight both the limits of the current approach to RIR and the potential to move it forward by drawing on relational analyses. I also provide guidelines for adjusting future work in this research program.
