Uncanny X-Men remains Marvel Comics' only Silver Age title to retain its consecutive issue numbering since its conception, even during the early 1970s reprint hiatus. The Amazing Spider-Man, Avengers, Captain America, Daredevil, Fantastic Four, Incredible Hulk, Iron Man, and Thor have all, at one time or another, restarted their numbering at #1; but all have returned to their original numbering. These revamps and renumberings took place in the 1990s. First in 1996, and again in 1998, for Avengers, Captain America, Fantastic Four, Iron Man, and Thor after the "Onslaught" and "Heroes Reborn" storylines, respectively; 1998 for Daredevil; and 1999 for Incredible Hulk. From issue #1 through #93 the indicia title was The X-Men. After the relaunch with issue #94, and up to #141, the article The was dropped from the indicia title making it X-Men. Beginning with issue #142, and up to #407, the article was re-added along with the adjective Uncanny to change the indicia title to The Uncanny X-Men. Issue #408 was the first to use the current indicia title, Uncanny X-Men.Uncanny X-Men all comes to an end thanks to the event known as "Schism"
As Axel Alonso has said about Schism:
"Schism is the X-Men's Civil War. The biggest X-event in a decade divides the mutant universe across distinct battle-lines and asks readers the question: Whose side are you on? And there's a reason Schism ends at exactly the same time as Fear Itself. Next summer, the entire Marvel Universe will have it's eyes on The X-Men."
