Catch up on 56 years of X-Men history in 25 moments

Fifty-six years is a pretty big chunk of time — especially when we’re talking about the mythology-heavy X-Men universe.

In an effort to bridge the gap between 1962 — the time when X-Men First Class took place — and the upcoming X-Men: Days of Future Past, set in 2018, Fox has unveiled an interactive history lesson in the form of a website titled 25 Moments.

The site sets up the Days of Future Past backstory by explaining 25 key events that have led to the dystopian world of 2018. Significant milestones and conflicts in human-mutant relations are highlighted, from President Nixon’s deals with the anti-mutant Trask Industries to the building of a massive “Mutant Wall” between the U.S. and Mexico for “security” purposes (Captain America: The Winter Soldier apparently has nothing on this film’s attempts at real-world allegory).

There are spoilerish updates on the fates of some familiar characters, as well as plenty of fun easter eggs, including a pic of baby Colossus (aw), born as a future X-Man as a result of the 1986 Chernobyl nuclear plant meltdown (ah).

X-Men: Days of Future Past hits theaters May 23.
