Garabet Ibrăileanu (May 23, 1871 – March 11, 1936) was a Romanian-Armenian literary critic and theorist, writer, translator, sociologist, Iaşi University professor (1908-1934), and, together with Paul Bujor and Constantin Stere, for long main editor of the Viaţa Românească literary magazine between 1906 and 1930. He published many of his works under the pen name Cezar Vraja.
Ibrăileanu was born into a family of Armenian origin, in Târgu Frumos, Iaşi County. During the 1890s, he was attracted to Socialism, and began collaboration with the left-wing press - periodicals such as Munca and Adevărul.
He adopted part of the themes and goals expressed by the defunct Junimea, merging them with the ideas of Marxist thinker Constantin Dobrogeanu-Gherea, into a new form of Romanian populism, making it the main attribute of the magazine he led. He is remembered as the first mentor to such diverse figures as Mihail Sadoveanu, Ion Agârbiceanu, Ionel Teodoreanu, Gala Galaction, Octavian Goga, George Topîrceanu, and Tudor Arghezi.
