This paper investigates the crisis in which provincial elections in Kirkuk has been enmeshed since the first provincial polls in post-Saddam Iraq held in 2005. It plots the trajectory of ethnic demographic changes in Kirkuk since the formation of the modern Iraqi state in 1921 and probes how these transformations inflamed discord along ethnic fault lines leading to excluding Kirkuk from two provincial elections, 2009 and 2013, till now. Tracing the intensification of the Kirkuk crisis against the backdrop of the failure of constitutional and legal solutions designed to resolve the so-called "disputed internal boundaries" problem, the paper analyzes the election results and demographic data in Kirkuk to shed light on the deepening electoral crisis in the province. It concludes by making recommendations aimed at reforming electoral registration in Kirkuk.
