Ever since Ryan Murphy revealed that all seasons of American Horror Story are connected, fans have been busy piecing together the disparate story lines into one cohesive universe. Sometimes this is quite easy, but other times it can be extremely tricky to see what your favorites from one season were up to during the events of another. Further complicating matters is the fact that Apocalypse introduced time travel, with one character traveling back in time, erasing the timeline we knew and creating a new one from that point on.

Since not everyone has the time to rewatch all the seasons to figure out how these things fit together, we put together a comprehensive timeline of the American Horror Story universe, encompassing all the most important events from Murder House, Asylum Coven, Freak Show, Hotel, Roanoke, Cult and Apocalypse.

*Note: Anything that is marked down as taking place in the "New Timeline" occurred in a year we had previously seen through the original timeline, but the events were changed by the time travel in Apocalypse.

Thomasin surrenders her soul to Scathach in order to survive. Newly empowered, Thomasin becomes the Butcher and returns to the colony where she slaughters the insurgents, but spares her son Ambrose.
