He was born in Erzurum in 1862 during the Ottoman Empire era. His father Hasan was a colonel in the Ottoman army. He completed his primary education in Erzurum and secondary education in Sivas and Amasya. He began his professional life as a clerk in 1881. Next year he voluntarily attended the army. But he resigned from the army in 1894 while he was a lieutenant. In 1897, he returned to his former profession as the chief clerk in the royal farm's directorate. During the First World War he established an institution for the orphans of the war.[1]

When Mustafa Kemal (later Atatürk) visited Amasya to declare his famous circular on 12 June 1919, he was one of the welcomers. He was elected as the Amasya MP from the Republican People's Party (CHP, then known as Halk Fırkası) in the First Parliament of Turkey on 23 April 1920.[2] In the parliament he was elected to the committee of Finance.
