This is a page for introducing newbies to various general alternate history conventions and to some notable examples of the genre (most of them published). It also serves as : 1.) A primer on how to start writing your own AH scenarios (also referred to as timelines - abbrev. “TLs”). 2.) A crossroad leading to the other major sections of the Wiki, which discuss alternate history concepts in a more in-depth and advanced manner. Head over there once you've mastered the basics. Among these more advanced sections, you'll also find lots of useful links to external resources, which may help a lot with creating your TL.
