Brighton & Hove Albion sealed promotion to the Premier League for next season and increased their lead at the top of the Championship to seven points with a 2-1 win over Wigan at a jubilant Amex Stadium on Monday.
The Seagulls last played in England's top flight in the 1982-83 season and will become the 48th team to play in the Premier League since it was introduced in 1992.
Brighton were officially assured of a top-two spot in the Championship and a promotion to the top flight after Derby County held Huddersfield Town to a 1-1 draw in the late game on Monday.
The result means the gap between Brighton and Huddersfield Town grew to 14 points, while the Terriers can only earn a maximum of 12 from their four games remaining.
Albion missed out on automatic promotion on goal difference on the final afternoon of last season, but that is now a distant memory for Chris Hughton's men.
"I don't necessarily think that was the motivation behind what we've been able to achieve this season," Hughton told Sky Sports. "I think the motivation was that they thoroughly enjoyed being at the top end of the table last season, all season."
Glenn Murray opened the scoring for Brighton eight minutes before half-time, his 22nd goal of the campaign and fifth in as many games at the Amex Stadium.
England under-21 international Solly March ensured the celebrations could continue in earnest when he converted Anthony Knockaert's cutback and a late goal from substitute Nick Powell could not change the picture.
At Derby, Collin Quaner had given Huddersfield a ninth-minute lead, and it looked as if Brighton's official welcome would have to wait until Jacob Butterfield scored from a deflected shot in the 88th minute for the hosts.
