Ash heap of history
The ash heap of history (also garbage heap of history, garbage dump of history, dustbin of history, or landfill of history) is a figurative place to where objects such as persons, events, artifacts, ideologies, etc. are relegated when they are forgotten or marginalized in history.
The expression arose in the 19th century in various places, but it was popularized by Leon Trotsky (in its Russian form Свалка истории, Svalka istorii, "garbage dump of history") in response to the Mensheviks walking out of the Petrograd Second Congress of Soviets, on October 25, 1917 (Julian calendar), thereby enabling the Bolsheviks to establish their dominance. Trotsky declared: "'You are pitiful, isolated individuals! You are bankrupts. Your role is played out. Go where you belong from now on—into the dustbin of history!'"
It has since been used literally and ironically in political and nonpolitical contexts.
It was used by Ronald Reagan in a speech to the British House of Commons on June 8, 1982. Reagan's speechwriter, Tony Dolan, chose the expression deliberately because of its prior context. His exact phrase was: "freedom and democracy will leave Marxism and Leninism on the ash heap of history". 
The phrase was also used by Libyan leader Muammar Gaddafi during a March 2011 speech. Speaking of the countries that attacked Libya during the implementation of a no-fly zone, Gaddafi stated, "This assault...is by a bunch of fascists who will end up in the dustbin of history".
