This thesis argues that while the equilibrium theories in civil-military relations literature criticise the separation theories for neglecting the domestic conditions of non-western states, they disregard the functional imperative and possible politicisation of militaries. In order to test this criticism of equilibrium theories, this thesis utilises Douglas L. Bland’s shared responsibility theory, which adapts the equilibrium approach by applying regime theory, to analyse the change in Turkish civil-military relations between 1999 and the present by conducting a longitudinal with-in case study of Turkey. The findings indicate that the characteristics of established equilibriums are conditional to the political context. In the case of Turkey, the change in civil-military relations mainly proceeded under competitive authoritarianism on the part of the government and resulted in a civil-military relations equilibrium that is stable at the moment but neglectful of the functional imperative and politicisation of the Turkish Armed Forces.
