When Was Warhammer 40K Created

Warhammer 40K: A Quick History for New Players

Most people asking When Was Warhammer 40K Created are looking for a single year, but the answer is messier than that. The original edition came out in 1987. Games Workshop released it as a futuristic battlefield spinoff of their successful Warhammer Fantasy Battle system. The game was based on the earlier Space Hulk rules, which had been around since 1985, and the lore was established through a series of sourcebooks rather than a single founding document. The first edition dropped in 1987, right around the same time the original Warhammer Fantasy Battle was getting its own second edition. GW clearly saw a market for sci-fi miniatures wargaming and used the same core mechanics. The ruleset from 1987 was rough. Movement, shooting, and combat all ran on a flat 2d6 roll-under system that barely differentiated between a Guardsman with a lasgun and a Marine in Terminator armor. It worked, but it was punishingly swingy. The second edition arrived in 1993 and completely overhauled the game. This is the edition most long-time players remember fondly. It introduced the chapter-specific codexes, the current point-based army building framework, and the codex structure that still defines the hobby today. Every major faction got its own book with army lists, background fluff, and special rules tailored to that faction. That format has barely changed in over thirty years.

Third edition came in 2004, fourth in 2008, fifth in 2012, sixth in 2017, seventh in 2021, and eighth in 2023. Each edition shifted the core mechanics more than the last. The game went from the old 2d6 system to a hit-point-based wound system, then to the current attack sequence where you roll to hit, roll to wound, and the opponent rolls saves. The 8th edition change to a simplified datasheet format was significant because it collapsed all faction data onto individual cards rather than burying it in thick rulebooks. I ran into a real problem when I was helping a friend get started. He wanted to buy a boxed set and play with friends who already had older models, but the editions were so far apart that unit stats were essentially incompatible. A Space Marines Tactical Squad from 7th edition has completely different stat lines, rules, and points from the same unit in 8th or 9th edition. You can't mix them in a competitive game without house-ruled compromises that break the balance. The workaround I use now is simple: check the year printed on the back of any model box or codex. If it's pre-8th edition, the unit is functionally dead for matched play. You can still use it for narrative games, but don't expect it to compete fairly. Here is something most beginners miss about the edition history. The lore did not advance linearly with the rules. The game's universe, as presented in the background books and rulebooks, has always been a fixed grimdark setting where humanity is stagnant and eternal. The rules change every few years, but the lore stubbornly stays the same. This means you can read a 1995 campaign scenario and a 2024 one and they describe the same galaxy, the same factions, and roughly the same state of war. The game mechanics evolve rapidly while the setting deliberately refuses to move forward in any meaningful way.

Another nuance that trips people up is the difference between the core rulebook and the codexes. The core rulebook contains the universal mechanics everyone uses. The codexes contain faction-specific rules, units, and background. If you are trying to understand what a specific army does, the codex matters far more than the core rulebook. If you are trying to understand how to play the game at all, the core rulebook is where you start. I see new players constantly buying a codex first and then being lost when they try to resolve a basic attack because they never picked up the core rules. If your goal is just to get an answer quickly, search for "When Was Warhammer 40K Created" and you will find 1987. But if you actually want to engage with the hobby, understanding the edition timeline matters more than the founding date. The gap between editions determines which models you can use, which rules apply, and which community resources are still accurate. Downloading an old PDF rulebook from 2007 might seem like a free shortcut, but it will give you incorrect mechanics and outdated army lists that will frustrate anyone trying to play a proper game.
