Ash heap of history
The phrase "ash heap of history", is a derogatory metaphoric reference to oblivion of things no longer relevant. In 1887 the English essayist Augustine Birrell (1850–1933) coined the term in his series of essays, Obiter Dicta: "that great dust heap called 'history.'" A notable usage was that of the Russian Bolshevik Leon Trotsky referring to the Mensheviks: "Go where you belong from now on – into the dustbin of history! " as the Menshevik faction walked out of the All-Russian Congress of Soviets on 25 October 1917 in Petrograd.
