Taqi Arani (Persian: تقی ارانی; 5 September 1903 – 4 February 1940), was a professor of chemistry, left-wing Iranian political activist and theorist as well as the founder and editor of the Marxist magazine Donya (The World).

[1] Arani was born in Tabriz and moved to Tehran with his family when he was four years old.

Upon finishing his studies, he returned to Iran in 1928 and started Donya magazine.

Many people consider Donya as his most important contribution to modern intellectual life in Iran.

[6] Although an important figure in the history of Iran's Marxist Left, Arani held strong Iranian nationalist and chauvinistic leanings early in his career[7] and wrote on the Iranian character of Iran's Azerbaijan region in response to pan-Turkist groups in Turkey of the 1920s.
