Just shy of a decade after that remarkable title triumph, the Foxes are preparing for life in League One next season, having suffered back-to-back relegations.
Their fate was sealed on Tuesday evening: a 2-2 draw with Hull City at the King Power Stadium confirming their place in the third tier for only the second time in the club's 142-year history.
It marks a sharp decline for a club that, during those 10 years, boasted two top-five Premier League finishes, an appearance in the quarter-finals of the Champions League – Europe's elite club competition – and FA Cup glory for the first time ever in 2021.
However, amid the highs, Leicester have also had to contend with some devastating lows during that time – most notably the death of owner Vichai Srivaddhanaprabha in a helicopter crash in October 2018.
A 5,000/1 fairytale
Leicester began the 2015/16 season as 5,000/1 outsiders to win the Premier League. The season before, they had consolidated their top-flight status by just six points, having secured promotion from the Championship the prior year.
Under the stewardship of Italian manager Claudio Ranieri, the Foxes defied the odds right from the start of the 2015/16 campaign, suffering just one defeat in their opening 17 league fixtures.
They were top of the table by mid-January, a position they never relinquished as they stormed to the title, finishing 10 points clear of runners-up Arsenal, having lost just three league games all season.
Striker Jamie Vardy, one of the poster boys of that success, finished on 24 league goals and became the first player to score in 11 straight Premier League matches – a record that still stands.
Champions League football came the following year, where Leicester progressed further than any other English team that season before exiting at the hands of Spanish side Atletico Madrid in the last eight.
The club's 'darkest day'
On 27 October 2018, little over two years after their league triumph, Leicester netted a late equaliser in a home game against West Ham to send fans inside the King Power Stadium into raptures.
But joy would turn to horror just hours later when five people – including the club's billionaire owner Mr Srivaddhanaprabha – were killed in a helicopter crash outside the ground, in what has been described as the "darkest day" in the history of the club.
All five victims were travelling on board the helicopter, which an inquest later found had suffered a mechanical failure that caused it to spin out of control.
In the days following the crash, wreaths were laid at the stadium, and tributes flooded in for a man many credit with turning around the fortunes of the club.
After buying Leicester for £39m in 2010, Mr Srivaddhanaprabha cleared the club's debts before overseeing one of the greatest sporting stories of all time six years later.
Following Vichai's death, his son Aiyawatt – known as "Top" – took charge of the club. Since then, however, the club has failed to sustain the same level of success.
A rapid decline
After lifting the FA Cup for the first time in the club's history in 2021 – courtesy of a Youri Tielemans goal in a 1-0 win over Chelsea at Wembley – Leicester, under boss Brendan Rodgers, finished eighth in the league the following year and also reached the semi-finals of the inaugural Europa Conference League.
But the season after, the Foxes struggled. Rodgers was dismissed in April 2023, and the team ultimately failed to avoid relegation to the second tier.
They returned to the Premier League after just one season away but came straight back down again in 2025. Since Rodgers's exit, the club has failed to establish stability in the dugout, having churned through six different permanent managers in just three years.
On-field issues have swiftly been followed by problems off it. In February this year, Leicester were deducted six points as punishment for exceeding the maximum loss threshold by more than £20m over the three-year assessment period ending in 2024.
Last month, the club reported another significant pre-tax loss of £71.1m during the 2024/25 season.
In recent years, Aiyawatt has wiped out hundreds of millions of pounds of the club's debt.
But that, as well as having one of the Championship's highest wage bills and boasting a squad brimming with international pedigree, could not save Leicester from slipping further down England's footballing pyramid.
Relegation to the third tier will have additional financial implications for the club and heap more misery on to an already frustrated fanbase.
The winning numbers in Tuesday's draw were 13, 16, 29, 40 and 47, with the Lucky Star numbers 3 and 4.
There were three winning tickets in total, including two bought in the UK and one bought in France.
They all matched the winning numbers and shared the jackpot, with a prize of £41,844,862.30 each.
Andy Carter, the senior winners' advisor at Allwyn, urged players to check their tickets, saying: "It's been another great night for EuroMillions players as two lucky UK winners have won an incredible share of tonight's £126 million jackpot prize.
"These lucky ticket-holders join the £181 million jackpot winner from 10 March – another big UK win."

Friday's jackpot is now an estimated £14m.
Just last month, another UK ticketholder won more than £180m in the EuroMillions jackpot draw.
The UK ticket holder matched all five main numbers plus the two lucky star numbers to land the third-biggest UK national lottery win of all time.
All told, they won £181,073,415.70, Allwyn said.
The record for the largest prize ever scooped by a UK EuroMillions player stands at £195m, which was won in 2022.
The final draft of the Tobacco and Vapes Bill completed its journey through the Commons and the Lords on Tuesday.
It will stop people who were born on or after 1 January 2009 from ever taking up smoking and will also give ministers new powers to regulate tobacco, vaping and nicotine products – including their flavours and packaging.
The bill will become law when it receives royal assent, which is a formality.
Its passage through parliament has been welcomed by charities and campaign groups, including Cancer Research and Asthma and Lung UK.
Michelle Mitchell, chief executive officer at Cancer Research, said: "This is a historic achievement that will shield our children from the devastating grip of tobacco addiction and help to put an end to cancers caused by smoking."
Sarah Sleet, chief executive at Asthma and Lung UK, said it would protect "vulnerable people around schools and outside hospitals" and prevent the tobacco industry from wreaking "havoc on the lungs of the next generation".

The ban was first mooted by Rishi Sunak's government but was shelved ahead of the 2024 general election.
It was revived by Labour when they took power and briefly considered taking it further – most contentiously by banning smoking in pub gardens and other outdoor areas.
Mr Streeting said: "Children in the UK will be part of the first smoke-free generation, protected from a lifetime of addiction and harm.
"Prevention is better than cure – this reform will save lives, ease pressure on the NHS, and build a healthier Britain."
Bang Si-Hyuk, who is the founder and chairman of Hybe, is being investigated over allegations that he told investors the company had no plans to go public, which convinced them to sell their shares to a private equity fund in 2019.
The company then proceeded with an initial public offering.
Police believe that the fund may have paid Bang, who is widely seen as one of the most powerful figures in South Korean music, around 200bn won (£100m) in a side deal.
The Seoul Metropolitan Police Agency has since asked prosecutors to request a court warrant for Bang's arrest.
Bang, who has been barred from leaving the country since August, denies any wrongdoing. His legal team told the Associated Press that they had offered "full and consistent cooperation with the investigation over an extended period".
"We will continue to cooperate with all legal procedures and make every effort to clearly explain our position," the statement said.
Bang is often credited with being behind the global success of BTS, who have become one of the biggest music groups on the planet.
In 2021, the firm secured management rights for other major global acts, including Justin Bieber and Ariana Grande.

The legal troubles come ahead of the group's highly anticipated global tour after an almost four-year hiatus as they served mandatory military service.
They are due to kick off a series of US events with a concert in Tampa, Florida, later this month.
A report from the office of Dame Rachel de Souza has found while the number of police strip searches of children has fallen by more than half in four years, there remain concerns about the use of force in some cases and persistent disparities in how white and black youths are treated.
Dame Rachel has said there should be a "much higher threshold" before a child is subjected to a "humiliating and traumatising" strip search.
Using data from the first half of 2024, her office estimated a total of 377 strip searches took place that year – down from 854 searches in 2020.
That was the year Child Q, a black teenager, was strip-searched in east London while on her period after police wrongly suspected her of carrying cannabis.
It did not come to light until a safeguarding report was published in March 2022, sparking protests.
The two Metropolitan Police officers involved in searching the 15-year-old were dismissed without notice after a disciplinary panel last summer found they had committed gross misconduct during the "disproportionate" incident.
'Too many still unnecessary'
Dame Rachel said the "promising signs of progress" since then in terms of the number of strip searches and how they are carried out have only masked the fact "that too many are still unnecessary, unsafe and underreported".
She described strip searching as "an intrusive and traumatic experience" that should "only ever be used as a last resort when there is an immediate risk of serious harm".
Her report found some searches between July 2023 and June 2024 were still being carried out in public view (26) and without an appropriate adult present (22).
Three in 10 (30%) involved children who had already been searched at least once before, which the commissioner said risked "significant and repeated damage to their mental wellbeing, their relationship with the police, and showing clear failure to successfully intervene with children".
Black children more likely to be subjected to force
Force, such as handcuffs or firearms and Tasers, was used in almost a fifth (17%) of all stop and searches of children between April 2024 and March 2025, but in 43% of instances where force was used, no further action was taken, raising the question why it was used at all.
Black children were almost five times as likely to have force used during a search than white children.
In cases where force was used against a white child to be searched, officers were more likely to note them as having a mental health need, but for black children the reason identified was more often their size or build, the report said.

The National Police Chiefs' Council said it understood that the "disproportionate use of stop and search" could "undermine trust between policing and communities".
But it said updates to official guidance on stop and search – including on the use of force and handcuffs – were out for public consultation and would help ensure all officers take a "child-centred approach".
A Home Office spokesperson said: "We're introducing extensive safeguards for children and young people for strip searching and bringing in reforms to drive up standards in policing, improve vetting and tackle misconduct."
