[X-Men] What events occur between the time of X-Men: The Last Stand and Logan (2017)?

#Spoilers for all X-Men movies below

**Original Timeline:**

**2013:** Logan travels to Japan. (*The Wolverine*)

**2015:** Xavier and Magneto find Logan at a U.S. airport. (*The Wolverine* ending)

**2023:** Sentinels hunt mutantkind. X-Men send Wolverine back in time. Wolverine wakes up in the body of 1973 Logan. (*Days of Future Past*)

As a result of Logan’s time-travel, the timeline is altered. People are born earlier or later. Events happen differently. Logically, only the timeline from 1973 and forward should be affected, but the movies haven’t really established how time-travel works in their universe. Therefore, there are also changes happening before 1973, such as Wade Wilson being born much later.

**Altered Timeline:**

**2023:** Logan wakes up in X-mansion after his time-travel adventure in *DoFP*. Sentinel future has been averted. X-Men still live in X-mansion. Jean and Cyclops (who died in *X3*) are alive.

**2029**: Events of *Logan*.

Apparently, something happens between 2023 and 2029 that causes eradication of almost all mutants.
