While Marvel continues to dominate the big screen and make advances on the small, DC is still trying to catch up. But with Batman v Superman: Dawn of Justice on the horizon and a number of (pretty good!) shows on the air, the big M could soon have some competition. DC's Batman-without-Batman prequel, Gotham, is set for its season finale tonight on FOX. And with the recent introduction of a kid Joker named Jerome, the show has truly gone in a strange (and sort of awesome) direction as of late. But how does the TV show fit into the larger DC Universe? Is Gotham considered "canon" or just its own weird thing? Was the Joker named Julian in The Dark Knight?

Last month, Complex took a look at the Marvel Universe—a complicated, convoluted, and confusing place itself—and attempted to set the record straight for newcomers. And now, with a similar goal in mind, we've decided to take on Marvel's biggest competition. Below find out how Superman, Batman, Wonder Woman, and Green Lantern's various comic book histories intersect, and what's in store for DC own cinematic universe. On the eve of Gotham's season finale, this is a beginner's guide to the DC Universe.

The DC Universe began before DC even existed.

The idea that comic book characters all occupied the same world was first introduced in 1940 by the comic All Star Comics #3. Before then, superheroes existed in their own realities and had their own adventures. At the time, DC as it's known now didn't exist yet, and its superheroes were spread out between All-American Publications and Detective Comics, Inc. (The two companies had the same CEO, though they operated as independent publishers. Both later merged into National Periodical Publications, which changed its name to DC—confusing, I know!)

Writer Gardner Fox, inspired by the National Baseball League, thought it would be neat if all All-American heroes came together to form a team. Thus, The Justice Society of America was born. The crew, featuring The Sandman, The Flash, Green Lantern, and more (Batman and Superman were still part of Detective Comics at the time), combine their powers to fight evil. Even so, it would be a long time before a solid continuity between the characters was expected by fans or created by the writers.

Even though it was established that various heroes could interact with each other, it would be a long time before DC took its shared world very seriously. The Golden Age (the 1930s through the mid 1950s) had occasional crossover issues, but didn't care much for matters of continuity. By the time The Silver Age arrived, which featured revamped backstories for many of the heroes, DC tried to make its various titles more coherent.

In Flash #123 it was explained that all the characters existed in a "multiverse"—a.k.a. a universe with infinite alternate realities. While most contemporary stories took place on Earth-One, DC could bring back Golden Age heroes or create alternate versions with the explanation that they were just visiting from another universe. Still, many origin stories didn't fit together and constant retcons made thing confusing. The DC Universe was still a mess, continuity-wise. 

DC rebooted completely with Crisis on Infinite Earths.
