History

History is linear.
Cyclic History is a type of history that is a cycle. All actions and events will eventually return to a cycle. There is no concrete or proven end or beginning.
Georg Wilhelm Friedrich Hegel disputed the cyclic theory. He stated Thesis+Antithesis= Synthesis

Vortex Theory of History revolves around the concept that history follows the path of a double-ended vortex: Big to little and little to big, constantly repeating.

The Hegelian Theory of History is the theory that is can be applied to most aspects of history. It is mostly a cause and effect chain, but not a cycle. History is inevitably caused by other actions and events. When two "causes" react and form a product, what we know of as history is formed. History may sometimes repeat itself but most of the time actions are produced by other actions and those actions lead to the formation of other actions and history becomes a sort of web linking many aspects of history to other distant parts in some way or another. The product of the addition of two separate actions can combine with another action to produce another effect that will continue a chain that never ends. This is what history is, a chain of events that are all interconnected and can be traced back for eons.
