A soapbox is a raised platform on which one stands to make an speech, often about a political subject. The term originates from the days when speakers would elevate themselves by standing on a wooden crate originally used for shipment of soap or other dry goods from a manufacturer to a retail store.
The term is also used metaphorically to describe a person engaging in often flamboyant impromptu or unofficial public speaking, as in the phrases "He's on his soapbox", or "Get off your soapbox." Hyde Park, London is known for its Sunday soapbox orators, who have assembled at Speakers' Corner since 1872 to discuss religion, politics, and other topics. Blogs can be used as soapboxes within the context of the World Wide Web.
Throughout the 19th Century and into the 20th, prior to the invention of corrugated fiberboard, manufacturers used wooden crates for the shipment of wholesale merchandise to retail establishments. Discarded containers of every size, well-constructed and sturdy, were readily available in most towns. These "soapboxes" made free and easily portable temporary platforms for street corner speakers attempting to be seen and heard at improvised "outdoor meetings," to which passersby would gather to hear often provocative speeches on religious or political themes.
The decades immediately preceding World War I have been called the "Golden Age of Soapbox Oratory." Working people had little money to spend and tub-thumping public speakers pushing their social or political agendas provided a form of mass entertainment. Radical political parties, intent on bringing what they perceived as an emancipatory message to the working class, were particularly intent upon making use of "street meetings," with their speeches and leaflets, to advance their specific message.
Street-corner oratory could also present its share of problems. Chief among these was the policy of local law enforcement authorities, who sometimes saw in radical political discourse a form of incitement to crime and violence and a threat to public order. Additionally, large street corner crowds listening to "soapboxers" would often obstruct public walkways or spill into public streets, creating inconveniences to pedestrians or vehicular traffic alike. Consequently, local authorities would often attempt to restrict public oratory through licensing or prescriptive banning.
