Justice League of America

The Justice League, also called the Justice League of America or JLA, is a fictional  superhero team that appears in comic books published by DC Comics.

First appearing in ''The Brave and the Bold #28 (February/March 1960), the League originally appeared with a line-up that included Superman, Batman, Wonder Woman, Flash, Green Lantern, Aquaman, and the Martian Manhunter. However, the team roster has been rotated throughout the years with characters such as Green Arrow, Atom, Hawkman, Hawkgirl, Black Canary, Zatanna, Captain Marvel, Plastic Man, the Elongated Man, Red Tornado, and dozens of others. The team received its own comic book title in October 1960, when the first issue was published, and would continue to #261 in April 1987, which was the final issue. Throughout the years, various incarnations or subsections of the team have operated as Justice League America, Justice League Europe, Justice League International, Justice League Task Force, Justice League Elite, and Extreme Justice.

Silver and Bronze Age / Justice League of America
Having successfully reintroduced a number of their Golden Age superhero characters (Flash, Green Lantern, etc.) during the late 1950s, DC Comics asked writer Gardner Fox to reintroduce the Justice Society of America. Fox, influenced by the popularity of the National Football League and Major League Baseball, decided to change the name of the team from Justice Society to Justice League. The Justice League of America debuted in The Brave and the Bold #28 (1960), and quickly became one of the company's best-selling titles. Fox wrote virtually all of the League's adventures during the 1960s, and artist Mike Sekowsky pencilled the first five years.

The initial Justice League lineup included seven of the DC superheroes being published regularly at that time: Superman, Batman, Aquaman, Flash, Green Lantern, Martian Manhunter, and Wonder Woman. However, Superman and Batman barely featured in most of the stories, not even appearing on the cover most of the time. Three of DC's other surviving or revived characters (Green Arrow, Atom, and Hawkman) were added to the roster over the next four years, the latter two having been revamped by Gardner Fox himself. JLA's early success was indirectly responsible for the creation of the Fantastic Four. In his autobiography Stan Lee relates how, during a round of golf, DC publisher  Jack Liebowitz mentioned to Marvel-Timely owner Martin Goodman how well DC's new book (Justice League) was selling. Later that day Goodman told Lee to come up with a team of superheroes for Marvel; Lee and Jack Kirby produced the Fantastic Four.

The Justice League operated from a secret cave outside of the small town of Happy Harbor,  Rhode Island. A teenager named Lucas "Snapper" Carr tagged along on missions, and he became both the team's mascot and an official member. Snapper, noted for speaking in beatnik dialect and snapping his fingers, helped the League to defeat giant space starfish Starro the Conqueror in the team's first appearance. In Justice League of America #77 (December 1969), Snapper was tricked into betraying the cave headquarters' secret location to the Joker, resulting in his resignation from the team. His resignation followed the resignations of two of the league's original members, Wonder Woman (in Justice League of America #69) and J'onn J'onzz (in Justice League of America #71).

Satellite years
In need of a new secure headquarters, the Justice League moved into an orbiting satellite headquarters in Justice League of America #78 (February 1970). Black Canary, Elongated Man,  Red Tornado, Hawkwoman,  Zatanna and Firestorm all joined the team during this period, and Wonder Woman returned. In the first two thirds or so of this era, the team was sometimes said to have a twelve-member limit and/or a "no duplication of powers" policy; this was formally rescinded in Justice League of America #146, allowing Hawkgirl to join.

Those involved in producing the Justice League of America comic during the 1970s include writers Denny O'Neil,  Mike Friedrich,  Len Wein,  Elliot S! Maggin,  Gerry Conway,  Cary Bates, E. Nelson Bridwell, and  Steve Englehart, with  Dick Dillin handling the art chores from issues #64-181, missing only one issue, #153. However, popularity waned around this time, leading to DC Comics to recruit popular artist George Pérez (who at the time was also drawing sister title The New Teen Titans) to replace Dick Dillin upon the artist's death. However, Perez would leave the title within two years in order to concentrate on the Titans.

Detroit
Seeking to capitalize on the popularity of their other team books, which focused upon heroes in their late teens/early 20s, Gerry Conway and artist Chuck Patton revamped the Justice League series. After most of the original heroes failed to arrive in order to help the team fend off an invasion of Martians, Aquaman dissolved the League and reformatted its charter to only allow heroes who would devote their full time to the roster.

The new team consisted of Aquaman, Zatanna, Martian Manhunter, the Elongated Man, the Vixen, and a trio of teenage heroes Gypsy, Steel, and Vibe. Aquaman would leave the team after a year and was replaced as leader by the Martian Manhunter. Because of his own edict of only wanting full-time heroes in the League, Aquaman's estranged wife Mera gave him an ultimatum to stay with either the group or with her to salvage their marriage. Fan response was largely negative and even the return of Batman to the team in Justice League of America #250 could not halt the decline of the series.

The final storyline for the original Justice League of America series (#258-261) by writer J. M. DeMatteis and artist Luke McDonnell, culminated a story-arc involving long-time Justice League enemy Professor Ivo's murders of Vibe and Steel (and the resignations of Vixen, Gypsy, and the Elongated Man) during the events of DC's Legends mini-series, which saw the team disband.
