UEFA Conference League - Kval

UEFA had reportedly considered adding a third-tier competition since at least 2015, believing that a bottom-level tournament could act as a means of giving clubs from lower-ranked UEFA member countries a chance of progressing beyond their customary elimination from the Champions League and Europa League. In mid-2018, talk of an announcement intensified, with news sources claiming an agreement had already been reached for the competition to be launched and that the 48-team Europa League group stage would be split in two, with the lower half forming the nucleus of what would be the new event.

On 2 December 2018, UEFA announced that the competition – provisionally known as "Europa League 2" or just "UEL2" – was to be launched as part of the 2021–24 three-year competition cycle, with UEFA adding that the new tournament would bring "more matches for more clubs and more associations".

The official name of the competition, "UEFA Europa Conference League", was announced on 24 September 2019.

On 24 May 2021, UEFA revealed the competition's trophy and brand identity. The Europa Conference League Trophy stands 57.5 cm (22.6 in) tall and weighs 11 kg (24 lb).

The first ever goal in the Europa Conference League qualifiers was scored on 6 July 2021 by Mosta player Evo Chris in a 2021–22 qualifying round match against Spartak Trnava. The first ever goal in the Europa Conference League group stage was scored on 14 September 2021 by Maccabi Tel Aviv player Stipe Perica in a 2021–22 group stage match against Alashkert. On 30 September 2021, the competition's first ever hat-trick was scored by Harry Kane for Tottenham Hotspur in a group stage match against NS Mura. Kane came on as a 59th minute substitute at 2–1 before scoring three goals within 20 minutes of each other to finish off the game (5–1).

On 24 February 2022, PAOK became the first ever team to win a Conference League tie on penalties, after beating Danish side Midtjylland 5–3 in a knockout round play-off match. On 5 May 2022, Feyenoord and Roma became the first teams ever to reach the final of UECL, ending with Roma being crowned the inaugural champions.

On 3 November 2022, West Ham United became the first side to win all six of their Conference League group stage matches, picking up wins against FCSB, Silkeborg and Anderlecht. They went on to win the competition by defeating Fiorentina 2–1 in the 2023 final, in the process becoming the first side to finish the competition undefeated, with 12 wins and one draw.

On 28 June 2023, UEFA announced that the competition will be renamed as the UEFA Conference League from the 2024–25 season onwards. According to UEFA, removing 'Europa' from the name of the competition will enable further development as a stand-alone competition in their research amongst fans and commercial partners.
