This chapter outlines the politics of inclusion in peace negotiations. It introduces and maps the debate on inclusion in the field, maintaining that it needs to be seen as an object of continuous political dispute. It argues that inclusion has gone from being considered an unnecessary disturbance to a necessary one in peace processes, especially due to its increasing association with the fostering of political legitimacy and peace sustainability. Even past its reconceptualization into a useful tool for the construction of peace, it is hierarchized and spatially, temporally, and thematically controlled so as not to jeopardize peace efforts. The chapter resorts to agonistic peace debates to contend that attaching inclusion to its usefulness limits it to a specifically political enclosure.
