Origins of Soapbox
A soapbox is a raised platform on which one stands to make an impromptu speech, often about a political subject. It is also used to express concerns or to release frustration.
The term originates from when speakers would stand on a wooden box meant for holding soap. 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 of your soapbox." Hyde Park, London is known for its Sunday soapbox orators, who have assembled at Speaker's Corner since 1872 to discuss religion, politics, and other topics. A modern form of the soapbox is a blog; a website on which a user publishes one's thoughts to whoever reads the page.
