It's a bittersweet time for One Direction fans: after five years, countless songs, memorable performances, and ever-changing hairstyles, Harry Styles, Liam Payne, Niall Horan and Louis Tomlinson are going on a break. Although they promised they will be back together eventually, we're entering a period without any new 1D related moments – and it's all kind of a lot to take in.
The boys returned to where it all began for them, X Factor during the weekend to give their farewell-for-now-sendoff performance and while they belted out their new single "History" while a montage of photos — including some with former bandmate Zayn Malik — flashed behind them, we couldn't help but think of how far the group has come and just how much they've accomplished in a short amount of time. World domination is no easy thing after all!
In honor of the guys' last appearance on the show that made them who they are— for now! — we decided to look back at all of their major milestones and how much they've transformed. Click through the gallery to see the best pics and GIFs and then tell us in the comments what your fave 1D memory is!
