The Long Depression was during industrial capitalism and lasted 23 years (1873 to 1896), if we consider 2009 to be the start of the current depression, totally reasonable to do so btw, then crossing 2033 would be the longest if they continue to decline.
The longest recession being the 60-year Great Slump in the 1400s.
