Under the AKP government, Turkey's influence has grown in the formerly Ottoman territories of the Middle East and the Balkans, based on the "strategic depth" doctrine (a terminology that was coined by Ahmet Davutoğlu for defining Turkey's increased engagement in regional foreign policy issues), also called Neo-Ottomanism. Following the Arab Spring in December 2010, the choices made by the AKP government for supporting certain political opposition groups in the affected countries have led to tensions with some Arab states, such as Turkey's neighbour Syria since the start of the Syrian civil war, and Egypt after the ousting of President Mohamed Morsi.
