author
A journalist and war correspondent, he is remembered for a vivid firsthand account of traveling into nationalist-held Anatolia during the Turkish War of Independence and meeting Mustafa Kemal. His writing offers a rare on-the-ground view of a turning point in modern Turkish history.

by Alaeddine Haïdar
Alaeddine Haïdar was a French-language journalist and war correspondent best known for À Angora auprès de Mustafa Kemal, a travel narrative about his journey in late 1920 from occupied Constantinople into Anatolia during the Turkish War of Independence.
The book is valued for its firsthand reporting: it follows his route through İnebolu and across Anatolia to Ankara, and includes an interview with Mustafa Kemal as well as a visit to the writer Halide Edib Adıvar. Modern descriptions of the work present it as a vivid, partisan, and readable window into the rise of the Turkish nationalist movement.
Reliable biographical details about Haïdar himself appear to be scarce in the sources I could confirm, so this overview focuses on the work for which he is known rather than making broader claims about his life.
