One Direction.

ONE DIRECTION

Band consists of Liam Payne, Louis Tomlinson, Niall Horan, Harry Styles and Zain Malik.
Niall Horan is the only Irish member of the band.
Louis Tomlinson is the oldest member - born 24 December 1991, while the youngest is Harry Styles who was born February 1st 1994. Liam Payne, Zain Malik and Niall Horan were all born in 1993.
Member Liam Payne had auditioned for "The X Factor" (2004) in 2008, making it to the judges houses stage before being sent home. Had he progressed to the live shows that year, Simon Cowell would've been his mentor then too.
Despite being put together as a boy band at the bootcamp stage of "The X Factor" (2004), they progressed the furthest out of all 4 of the acts in the "Group" category (all of whom were mentored by judge Simon Cowell), finishing in third place.
Each member of One Direction auditioned for the 2010 season of "The X Factor" (2004) as soloists and made it to the bootcamp stage. However, the judges felt they were too good to throw away, but not interesting enough to make it as soloists and were given a lifeline to proceed in the competition as a group.
