The phrase "slough of despond" comes from John Bunyan's allegorical novel "The Pilgrim's Progress," published in 1678. In the story, the Slough of Despond is a place of deep despair and difficulty that the protagonist, Christian, must navigate on his journey to the Celestial City. It has since become a metaphor for a state of deep despair or hopelessness.

Slough of Despond

The correct spelling is "slough," as in the idiom the "slough of despond."

It is a metaphor for the Christian's journey to heaven, the main character being called Christian. He encounters obstacles like the Slough of Despond-a slough being an area of swampland, despond being depression. Needless to say, it has nothing to do with US History.
