Strauss-Howe generational theory – Wikipedia, the free encyclopedia.
Strauss and Howe lay the groundwork for the theory in their 1991 book Generations, which retells the history of America as a series of generational biographies going back to 1584.[1]
In their 1997 book The Fourth Turning, the authors expand the theory to focus on a fourfold cycle of generational types and recurring mood eras in American history.[2]
The theory was developed to describe the history of the United States, including the 13 colonies and their Anglo antecedents, and this is where the most detailed research has been done. However, the authors have also examined generational trends elsewhere in the world and identified similar cycles in most of today’s developed countries.[3]
