Damluji was one of the physicians who served in the Ottoman army during the Balkan War in the period 1912–1913.[2] He was part of an Arab nationalist Ottoman military club led by Aziz Al Misri in Constantinople.[3] Members of the club including Damluji had to leave the city because of their nationalist affairs and settled in Cairo in Spring 1914.[2][3] After a while Damluji went to Basra and then to Riyadh where he joined the entourage of Ibn Saud as a physician in 1915.[3][5][6] He was made a member of the royal court accompanying the foreign visitors[5] and also, joined the Saudi delegations to foreign visits. In one of such visits Damluji accompanied Ahmed Al Thunayan, Saudi foreign affairs advisor, in Baghdad in February 1920.[7] Damluji along with Hafiz Wahba also acted as a tutor to Prince Saud, son of Ibn Saud.[8] As of 1922 Damluji was serving as the representative of Ibn Saud, Sultan of Najd[1] and replaced Ahmed Al Thunayan as his chief foreign affairs advisor.[9]
In 1924 Damluji was sent to Mecca together with Hafiz Wahba and Abdullah Suleiman following the capture of the city to monitor the social, cultural, political and economic conditions.[10] In 1926 he became Ibn Saud's personal representative in Hejaz.[5] In the same year Damluji was appointed the deputy minister of foreign affairs which he held until 1928 when he was replaced by Fuad Hamza in the post.[4][5] In fact, Damluji was the foreign minister of Najd and Hejaz.[11]
Damluji represented the Court of Nejd, the Hejaz and its dependencies at the Medina Railway Conference held in Haifa in August 1928.[12] The conference was a failure which led to a border crisis between Saudi and Iraqi authorities.[12][13] Due to this incident he resigned from office and did not returned to Arabia.[12] He first went to Syria and then to Lebanon.[13] He eventually returned to his native Iraq in September 1928[14] where he became the consul-general of Iraq in Cairo.[2] He was appointed minister of foreign affairs of Iraq in the cabinet led by Nuri Pasha Said in 1930.[2][15] Damluji's tenure ended in October 1932 when Nuri Pasha Said resigned from the post.[16] Immediately after this incident Damluji was named as the ambassador of Iraq to Turkey.[16]
Damluji was elected as the deputy for Mosul and was appointed director general of public health in 1932.[2] He was made the chief chamberlain to the King in 1933 and was again appointed minister of foreign affairs in February 1934 which he held for one year.[2][17] The cabinet was led by Prime Minister Jamil Al Midfai.[17] From 1934 to 1936 Damluji was director general of public health.[2]
