Ottoman era
He was born in 1873 in Bursa of Turkish descent. His father, Field Marshal (Müşir) İbrahim Pasha was a high-ranking officer in the Ottoman Army. He entered the Ottoman Military Academy (Mekteb-i Füsûn-u Harbiyye-i Şâhâne), in Pangaltı, in 1890. He completed the Military Academy as the 31st of the class in 1893 and joined the Ottoman military as an infantry second lieutenant (Mülâzım-ı Sani). He knew Arabic, French, German, and Russian. On 31 January 1895, he was promoted to the rank of first lieutenant (Mülâzım-ı Evvel) and, on 22 July 1895, to that of captain (Yüzbaşı). Nureddin Bey joined the Committee of Union and Progress (membership number was 6436). On 19 August 1909, he was demoted to major, because of the Law for the Purge of Military Ranks (Tasfiye-i Rüteb-i Askeriye Kanunu) and then pursued his retreating opponents to the town of Kut. Several attacks failed to take the town, and he settled down to a siege which ended in a British surrender. German Generalfeldmarschall Colmar von der Goltz arrived at Baghdad on 21 December 1915, changed the name of the Command as the Iraq Army (Irak Ordusu), inspected his positions and later left to start an invasion of Persia. On 20 January 1916, Enver Pasha, Ottoman Minister of War, replaced Nureddin Bey with Colonel Halil Bey and Nureddin Bey was appointed to the commander of the IX Corps and the provisional commander of the Third Army. He was promoted to the rank of Mirliva in 1918.
Nureddin Pasha established a consultation committee consisting of delegates of parties, societies and merchant clubs in Smyrna (Izmir), and supported activities of the Society for the Defence of Ottoman Rights in Izmir (İzmir Müdafaa-i Hukuk-ı Osmaniye Cemiyeti). However, activities of the society slowed down with Nurettin Pasha's departure from İzmir. In order to weaken Turkish defense against Greek landing at İzmir, The Allied Powers, especially the British Prime Minister David Lloyd George, wanted to remove Nurettin Pasha from İzmir. Before the Occupation of İzmir, nationalist general Nureddin Pasha was recalled the Governor, who had fallen foul of Chrysostomos of Smyrna. Kurd Ahmet Izzet Pasha was appointed as the new governor on 11 March, and retired general Ali Nadir Pasha was appointed as the new military commander on 22 March. He expelled American missionaries and put some local Christians on trial for treason.
