JUSTICE SOCIETY OF AMERICA

The Justice Society Infinity
& Earth-2 Chronology

+ Assumptions

The current timeline of Earth-2 is the same as that of the original (pre-Crisis) Earth-2. It is explained that the residents of Earth-2 lived through the Crisis, but then afterwards, were unable to breach the barrier between universes. Essentially, life carried on. This is similar to the circumstances for the original Legion's continuity—they remember the Crisis but afterwards they were unable to travel back through time.
The JSA's Golden Age events does not include Young All-Stars, which was created to fill the gaps in continuity after the first Crisis. Also, it's pretty easy to tell when events from Infinity Inc. began to be told from to a post-Crisis perspective. I end with issue #24, the last issue before character histories began to change. That said, in this new EArth-2, the Infinity, Inc. history could be entirely different as well. It is possible that upon their initial bid for membership, the JSA agreed and the two organizations merged right away.
Some details revealed in the post-Crisis tales in Secret Origins are included here if they do not contradict any original tale(s). The Secret Origins tales were largely written by Roy Thomas, who knew these characters intimately. It is usually easy to tell when Thomas intended for events to fit with original continuity, and when he intended to change events for post-Crisis continuity.
Post-Crisis tales of Earth-2 are included. There aren't many. They include the Gentleman Ghost story from JSA #83-85 (2006) and the introduction of Justice Society Infinity in Justice Society Annual #1 (2008).

+ Standards

Color Codes:

Major story arcs (usually 3 issues or more).

A new member joins the JSA.

A hero dies

Issue information in parentheses indicates one of two things: (a) the tale was retold/corroborated in additional stories, and/or (b) the tale was told out of chronological order.
Characters' first appearance IN PRINT is bolded. These instances refer to the first appearance a character in post-Crisis continuity. (For example, Brain Wave: 1st chronological app. in All-Star Squadron #19, and 1st app. In print is All-Star Comics #15.)
When the placement of a tale within continuity is in question, the tale is usually placed in the most recent possible time.
Only the inheritors to a title display the level of succession. Example: "Green Lantern II" (for Hal Jordan), but just "Green Lantern" (no "I" for Alan Scott).
Consideration for inclusion is based on an event's relevancy to the JSA, its members, and their legacy. This includes major JSA series and key issues from other DCU series.
