Who will guard the guardians? Political scientists since Plato have sought to answer this, the central question of the civil-military relations subfield. Although civil-military relations is a very broad subject, encompassing the entire range of relationships between the military and civilian society at every level, the field largely focuses on the control or direction of the military by the highest civilian authorities in nation-states. This essay surveys political science's contribution to our understanding of civil-military relations, providing a rough taxonomy for cataloguing the field and discussing the recent renaissance in the literature as well as fruitful avenues for future research. The essay focuses on theoretical developments, slighting (for reasons of space) the many case studies and empirical treatments that have also made important contributions to our knowledge.
