He was a legal counsel for the Ottoman Ministry of Foreign Affairs, when he saw the birth of his first son, Nesuhi, on 26 November 1917, in Constantinople (now Istanbul), during the First World War. Taking part in an Ottoman delegation with a mission to search reconciliation with the Nationalists in Ankara, by the end of 1920, changed his destiny. While the two Ottoman Ministers heading the delegation returned to Istanbul after not achieving an understanding with the revolutionaries led by Mustafa Kemal Pasha he chose to join the National Struggle and remained in Ankara, leaving behind his young wife and three-year-old son, Nesuhi. He became an aide to Mustafa Kemal during the Turkish War of Independence and the chief legal counsel of the Turkish delegation to the resulting Treaty of Lausanne in 1923.

Passage: Columbia (; ) is the female personification of the United States. It was also a historical name used to describe the Americas and the New World. It has given rise to the names of many persons, places, objects, institutions and companies; for example: Columbia University, the District of Columbia (the national capital of the United States), and the ship Columbia Rediviva, which would give its name to the Columbia River. Images of the Statue of Liberty largely displaced personified Columbia as the female symbol of the United States by around 1920, although Lady Liberty was seen as an aspect of Columbia. The District of Columbia is named after the personification, as is the traditional patriotic hymn "Hail Columbia", which is the official vice presidential anthem of the United States Vice President.
