[2] A Poporanist who had joined the circle formed around Viața Românească, Iordan engaged in politics during 1918, and was active, alongside Paul Bujor, Constantin Ion Parhon, Octav Băncilă, Ioan Borcea, and Nicolae Costăchescu, in the short-lived Laborer Party (Partidul Muncitor).
[5] Four years later, he quit the PNȚ for unknown reasons, and was subsequently active in marginal anti-fascist political groupings connected with the Romanian Communist Party (PCR), encouraged by the Comintern as an effect of the Popular Front doctrine.
[6] He contributed to the leftist press, took part, alongside Petre Constantinescu-Iași and Ion Niculi, in forming the Amicii URSS ("Friends of the Soviet Union") society, and was believed by the far right to be a communist.
[20] Among those whose career was affected a result of Iordan's verdicts was the writer Paul Goma (expelled from the Literature Institute for, among others, having questioned the scientific value of Moldovenism and the status of Russian as the foreign language of choice in Romanian schools).
[21] After briefly serving as head of the National Theater Iași (in 1945, during the time when it had taken refuge in Sibiu), Iordan was also present on the board of Editura Cartea Rusă, which published works of Russian literature.
