Jordan Rhodes opened the scoring for Blackburn Rovers in the 24th minute before Jason Shackell and Danny Ings inspired a second-half comeback late on for Burnley.
This was Burnley’s first win over Blackburn since 1979 as they came back from a goal down at Ewood Park.
This was Burnley's 4th consecutive season in the Championship after their relegation from the Premier League in the 2009/10 season.
The Claret's were unbeaten since Boxing Day 2013 coming into the derby game. They lost 1-0 to Middlesbrough but since then, they had been unbeaten for 11 League games.
Burnley were pushing for automatic promotion as they sat in 2nd place. The Clarets needed a win to close the gap on the league leaders Leicester City. Blackburn were in 10th place, sitting six points outside the play-offs.
Sean Dyche played the exact same team that started in their previous fixture against Derby County in a 2-0 home win for the Clarets.
The line-up consisted of Tom Heaton, Kieron Trippier, Ben Mee, David Jones, Michael Duff, Shackell, Scott Arfield, Dean Marney, Ings, Sam Vokes and Michael Kightly.
The first-half didn't begin so well for Burnley as Jason Lowe whipped in a low cross to Rhodes who turned and finished past Heaton to give Blackburn the lead.
The game was in Blackburn's favour until Burnley got a free-kick 30 yards from goal. Substitute Ross Wallace stood over the free-kick and curled a delightful ball to the back post. Captain Shackell beat Paul Robinson to the ball and headed the equaliser with just over 15 mins to go.
Burnley were in the ascendency and they got the winner with just over 10 mins to go. Trippier crossed towards the back post to find Arfield who brought the ball down excellently.
Arfield's cross found Wallace at the back post whose deflected pass fell straight to Ings who fired underneath the keeper to send the away fans into ruptures.
What happened next?
An inspired substitution from Dyche helped Burnley to a big win over their bitter rivals. Wallace came on and completely changed the game for the Clarets.
The scenes in the away end continued as Burnley gained automatic promotion, finishing in 2nd place.
Top goalscorer Ings continued his inspired form in the Premier League, scoring 12 goals but it wasn't enough for Dyche's men as they finished 19th.
Burnley were promoted back to the Premier League the following season but this time they went up as champions.
