He entered the Hellenic Army Academy and graduated in 1887 as an Engineer 2nd Lieutenant.
Subsequently, Nider served for eight years in the Austro-Hungarian Geodetic Mission to Greece, which laid the foundations of the Greek Army"s own Geographic Service. Promoted to Lieutenant in 1890 and Captain in 1898, he was sent to France for further studies in 1903. Upon his return he was promoted to Major and placed in the newly established General Staff, and then in the staff of the 3rd Infantry Division.
He was promoted to Lieutenant Colonel in 1911.
Venizelos" victory led to the immediate entry of the whole country into World War I on the side of the Entente, and Nider was given command of the 1st Infantry Division. In December 1918, he was given command of I Army Corps, which soon after participated in the Allied intervention in Southern Russia, fighting the Bolsheviks in the Crimea and Odessa.
On 2 June 1919, he was appointed head of the Greek Army of Occupation for the zone around the city of Smyrna (Izmir). He held this post until December, when he returned to his duties as Colorado of I Corps, which formed part of the occupation force.
Nider fought in the subsequent battles of the Greco-Turkish War of 1919–1922 from the same post, until he was replaced in February 1922.
Following the Greek defeat in Asia Minor in August 1922 and the overthrow of the royal government by Venizelist officers, Nider was recalled to active service and placed at the head of the Army of Thrace until his resignation in December 1923.
