User:MrBlonde267/Batman and Earth-One

It can be difficult figuring out Batman continuity. The Batman of the Golden Age is said to have existed on Earth-Two, and the Batman of the Silver Age is said to have existed on Earth-One. These distinctions were made in other books, so there was no intentional change by the Batman writers. This means that there is not a clear distinction in Batman history of when Earth-Two continuity ends, and when Earth-One continuity begins. There have been several attempts to make a clear ruling. The reality is that there is a lot of overlap. Later writers would pick and choose stories by their own determination. This page will attempt to map out this confusing continuity.

Beginning of Earth-One
These are the stories that are traditionally considered to be the "beginning" of Earth-One, at least as it pertains to Batman.
 * 1955 - : This is the first appearance of Martian Manhunter. He would later be established as exclusive to Earth-One, making him the first distinctly Earth-One character. This is the first time Batman appears in a book with an Earth-One character. They do not appear in the same story.
 * 1960 - : This is the first time Batman appears in a story with distinctly Earth-One characters, specifically Barry Allen and Hal Jordan.
 * 1961 - : This is the first story that actually names and establishes "Earth-One." Batman does not appear.
 * 1964 - : This is the official first appearance of Batman on Earth-One, as listed in Who's Who #2.
