As England, Northern Ireland, Republic of Ireland and Wales look ahead to Euro 2016, we relive the high and lows of their successful qualification campaigns.
Football fans from Britain and Ireland will flock south next summer to partake in what's set to be a feast of football in France.
But how did each respective nation book their place at the finals? Before the focus switches to the Euros, we look back on each campaign individually.
England
It was the perfect qualifying campaign from England as they won all 10 matches to emerge as clear winners of Group E.
An opening 2-0 win in Switzerland set England on their way and they followed it with a thumping 5-0 victory over San Marino. A third straight win looked to be in the balance in Estonia until Wayne Rooney popped up with a 74th-minute winner.
Further victories followed over Slovenia and Lithuania before England almost dropped their first points of the campaign in Ljubljana. Jack Wilshere twice put England ahead but they needed an 86th-minute strike from Rooney to secure the points after Slovenia had levelled at 2-2.
From then on it was plain sailing for the Three Lions as they did not concede a goal in their final four matches. They beat San Marino, Switzerland, Estonia and Lithuania to become only the sixth team to complete a perfect European Qualifying campaign.
Northern Ireland
After learning of Northern Ireland's opponents in Group F, finishing top was far from manager Michael O'Neill's mind. "You could possibly get third place with 14 points, which I think is achievable," he said at the time.
However, Northern Ireland not only qualified for the European Championship for the first time, they won the group, becoming the first fifth seeds to top a Euro qualifying group.
They made a fine start as late goals from Niall McGinn and Kyle Lafferty secured a 2-1 win in Hungary, giving Northern Ireland their first competitive away win for two years. Lafferty also scored in wins over Faroe Islands and Greece before a 2-0 defeat to Romania saw Northern Ireland slip to second in the group.
However, they bounced back with a home win over Finland, a goalless draw with Romania and then victory against the Faroe Islands. The key result of the campaign, though, came against Hungary in Belfast as Lafferty scored an injury-time equaliser to snatch a point for the 10-man hosts.
A 3-1 win over Greece sealed Northern Ireland's place in France and they capped off a fantastic campaign by drawing in Finland to finish top.
Republic of Ireland
Following the draw for the European Qualifiers, it appeared Ireland and Scotland would battle it out for the play-off spot behind higher-ranked nations Germany and Poland.
However victory in Georgia, a 7-0 demolition of Gibraltar in Dublin and a last-minute John O'Shea strike to secure a draw in Germany saw Martin O'Neill's side emerge as automatic qualification contenders after the opening three rounds of fixtures.
Such high aspirations came crashing back down to earth as the Green Army failed to win any of their following three games, losing in Scotland before being held to draws in Dublin against the Poles and Scots.
A timely victory in Gibraltar, coupled with Scotland's failure in Georgia, presented Ireland with the chance get their campaign back on track, and it was an opportunity they took in spectacular fashion.
First they succeeded where Scotland had failed, winning in Tbilisi, before Germany were defeated on a memorable night at the Aviva Stadium.
Defeat in Poland ended Ireland's hopes of automatic qualification, but a 3-1 aggregate victory over Bosnia-Herzegovina saw them qualify for a second successive European Championship via the play-offs.
Wales
Chris Coleman masterminded a stunning qualification campaign for Wales as they brought a 58-year wait for major tournament appearance to a timely end.
A campaign built on defensive solidity and unity got off the perfect start as Gareth Bale, the poster boy of the Welsh campaign, snatched a late victory in Andorra in their opening game.
The Welsh went from strength to strength, going on to concede just four goals throughout qualification, a defensive record which earned them four points from a possible six against eventual group winners Belgium, key results in their push for qualification.
June's 1-0 victory over Belgium - now the world's No 1 ranked side - proved to be the catalyst for qualification, with victory in Cyprus and a draw in Israel all-but sealing Wales' passage.
Wales tasted defeat for the first time in their penultimate group game, away to Bosnia-Herzegovina, but it proved to be irrelevant as Israel's defeat to Cyprus sealed qualification and with it mass celebrations in Zenica. The wait was finally over.
