According to the authors' 1997 book, The Fourth Turning, modern history repeats itself every four generations; approximately 80–100 years. The authors of the book mention that the four-cycles always come in the same order. The first one, the High cycle, occurs when a new order or human expansion is developed, replacing the older one. The next cycle is called the Awakening. More spiritual than the previous, this is a time of rebellion against the already established order. The third cycle is known as the Unraveling, when elements of individualism and fragmentation take over society, developing a troubled era which leads directly to the Fourth Turning, an era of crisis dominating society during which a redefinition of its very structure, goals, and purposes is established. The book can be found here.
