The Walking Dead Comics Reading Order/Timeline, a Zombie post-apocalypse universe by Robert Kirkman
There is no doubt that The Walking Dead is one of the most popular comic book series, gaining widespread recognition at the start of the 2010s with the television adaptation by AMC. Now a media franchise, it includes seven live-action television series, eight web series, several video games, novels, a role-playing game, and even an indoor roller coaster haunted attraction at Thorpe Park in England. The zombie apocalypse that captured the world’s attention began in 2003 with the original comic series.
Created by Robert Kirkman (Invincibles) and Tony Moore, The Walking Dead almost didn’t see the light of day as the two men struggled to sell their pitch. Their initial proposal, titled Dead Planet, was set in the 27th century, where a mysterious mineral on a newly discovered planet turned people into zombies, intended as a weapon. After Image Comics rejected the idea, Kirkman returned with a reworked concept, this time set on Earth and centered around the Grimes family during a zombie apocalypse in the 1960s. The comic series was initially called Night of the Living Dead, after the 1968 George Romero classic film. However, Image Comics co-founder Jim Valentino pushed for a more original concept, one with no ties to another classic zombie story.
Kirkman then proposed The Walking Dead with a more traditional approach, but the pitch was again rejected for being “too normal.” To secure the green light from Image Comics, Kirkman added a twist: the zombie plague was caused by aliens, turning the story into an alien invasion tale. Although this secured approval, Kirkman never actually intended to include aliens in the comic book.
Drawing inspiration from 28 Days Later (itself a nod to The Day of the Triffids), The Walking Dead begins with Rick Grimes, a Kentucky deputy who is shot in the line of duty and awakens from a coma to find that the world as he knew it is gone. In just a few months, society has crumbled: no government, no grocery stores, no mail delivery, and no cable TV. An epidemic of apocalyptic proportions has swept the globe, causing the dead to rise and feed on the living. With his family missing, Rick travels to a military evacuation zone in Atlanta to find them and joins a small group of survivors along the way, all while trying to adapt to life in this terrifying new world…
