Late in his life, Iorga opposed the radically fascist Iron Guard, and, after much oscillation, came to endorse its rival King Carol II. Involved in a personal dispute with the Guard's leader Corneliu Zelea Codreanu, and indirectly contributing to his killing, Iorga was also a prominent figure in Carol's corporatist and authoritarian party, the National Renaissance Front. He remained an independent voice of opposition after the Guard inaugurated its own National Legionary dictatorship, but was ultimately assassinated by a Guardist commando.
