AC Milan was founded as Milan Foot-Ball and Cricket Club in 1899 by English expatriates Alfred Edwards and Herbert Kilpin. The club claims to have founded on 16 December as the date they founded their club however the evidence from history suggests that it was established a few days earlier, probably on the 13th day of December. But, due to the charter of the club being lost the exact date is subject to debate.
In honor of its English origins, the team retains its English version of Milan's city name in contrast to its Italian name, Milano Milano, which it was forced into in the fascist regime. Milan took its first Italian champion at the age of the year 1901 and then two more successively between the years 1906 1907 and 1907.
It was 1908 when Milan was divided in 1908 that was caused by internal conflicts concerning the signing of foreign players. This led to the creation of another Milan-based club, F.C. Internazionale Milano. In the aftermath of these incidents, Milan did not manage to secure one domestic title until 1950-51.[9 The 1950s saw Milan rise up to the top ranks in Italian football, led by the legendary Gre-No Li Swedish trio of Gunnar Gren, Gunnar Nordahl and Nils Liedholm. It was one of Milan's most successful times domestically and internationally, including the Scudetto being awarded to Milan in 1953, 1955 1959, and 1962. It was in 1963 that Milan was awarded its very first European title when it beat Benfica at the final of the European Cup. The victory continued during 1969 when Milan won the team winning 4-1 against Ajax during final that then led to winning the Intercontinental Cup title the following year. The time was also a period when Milan also was the first to win the Coppa Italia, with victory against Padova in the final in 1967 and the European Cup winners' cup twice during the years 1967-1968, and 1972-1973.
Milan achieved the 10th league title in 1979, when Milan won a tenth league title however, following the departure from Gianni Rivera during the same season it entered an era of decline. The team in the year 1980 was implicated with an incident known as the Totonero incident and, as a result, was was relegated to the Serie B for the first time in the history of the club. The scandal revolved on a betting syndicate that paid officials and players to alter the outcomes of games. Milan was promoted into Serie A on the first try and won their 1981-82 Serie B title, but they were then relegated after the team concluded the 1981-82 season in the third position. It was in the year 1983, Milan won the Serie B title for the second time in the span of three seasons before returning back to Serie A, where they finished sixth at the end of 1982-84.
20 February 1986 was the date that the entrepreneur Silvio Berlusconi (who has control of Fininvest Mediaset and Fininvest Mediaset) purchased the team and protected it from going bankrupt after investing huge sums of money. He also appointed new manager Arrigo Sacchi as the manager of the Rossoneri and signing Dutch internationals Ruud Gullit, Marco van Basten and Frank Rijkaard. The Dutch trio provided an aggressive edge to the team and also complemented the team's Italian nationals Paolo Maldini, Franco Baresi, Alessandro Costacurta and Roberto Donadoni. Under the leadership of Sacchi, Milan won its first Scudetto in nine years during its year 1987-1988. The next year, the team was awarded the very first European Cup in two decades, defeating Romanian team Steaua in Bucuresti by a score of 4-0 during final. Milan retained their title with a 1-0 win over Benfica a year later and was the last team to win back-to-back European Cups until Real Madrid's victory in the 2017 season. The Milan team from 1989-1990 was dubbed the "Immortals" by the Italian media was named the most successful club side ever in an international poll of experts carried out by World Soccer magazine.
After Sacchi quit Milan in 1991 He was replaced in 1991 by former Milan player Fabio Capello. The team was able to win the club's three successive Serie A titles between 1992 between 1992 and 1994, a period that saw a 58-match winless streak through Serie A (which earned the team the title "the Invincibles"), and back-to-back UEFA Champions League final appearances in 1993 1994, 1993 and 1995. After losing 1-0 against Marseille during the 1993 Champions League final, Capello's squad reached its peak during one of Milan's most memorable games ever the famous 4-0 victory against Barcelona at 1994's 1994 Champions League final. Capello's team would go to claim in the the 1995-1996 league title before leaving to run Real Madrid in 1996. Then, in 1998-99 after two years declining, Milan lifted its 16th title in the club's century-year celebrations.
The next phase of Milan's success was from another player who was a former one, Carlo Ancelotti. After his appointment in November 2001, Ancelotti took Milan to the 2003 Champions League final, where they defeated Juventus winning on penalties this club's 6th European Cup. The team then won the Scudetto in 2003-04 before reaching the 2005 Champions League final, where they were beaten by Liverpool on penalties despite being ahead 3-1 at half-time. The following year they met once more during the 2007 Champions League final, which ended with Milan beating Liverpool 2-1 to claim the trophy for the seventh time. The team also was awarded their initial FIFA Club World Cup in December 2007. In 2009, after becoming Milan's second longest serving manager with 420 matches overseen, Ancelotti left the club to take over as manager at title="Chelsea F.C. ">Chelsea.
At the time it was also involved during that time, the club was involved in the Calciopoli controversy in which five teams were accused of rigging matches through the use of referees with favorable ratings. A police investigation ruled out the involvement by Milan managers, however, it was the Italian Football Federation (FIGC) independently decided that it had enough evidence to indict Milan vice president Adriano Galliani. The result was that Milan was initially penalized with a 15-point deduct and was barred from participating in the 2005-07 UEFA Champions League. A re-appeal saw the penalty decreased to eight points that allowed Milan to keep the Champions League participation.
After the events of Calciopoli, local rivals Internazionale had a dominant performance in Serie A, winning four Scudetti. But with the assistance of with a formidable squad featuring players like Zlatan Ibrahimovic Robinho as well as Alexandre Pato along with many of the veteran players who played for the team during the middle of their European achievements, Milan recaptured the Scudetto in the 2010-11 Serie A season, their first since 2003-04 and finishing 18th overall.
After the Scudetto, the club's performance deteriorated. The club failed to reach European tournaments for several years. Fininvest the holding company for the club, also has signed an agreement in principle in 2015 with Bee Taechaubol to purchase a 48% in the team to the tune of EUR480 millions in the year 2015. The deal came after the net deficit of EUR91.3 million during the 2014 financial year , and a subsequent financial contributions from Fininvest. However, the deal fell apart.
On the 28th of June, the year 2016, Vincenzo Montella was hired as manager.
On August 5, 2016 a new preliminary agreement was concluded with an Chinese investment management firm Sino-Europe Sports Investment Management Changxing Co. This was the day that Fininvest purchased 99.93 percent stake in Milan for around EUR520 million, which included the rehabilitation of the club's and financial obligations of EUR220 Million. On April 13, 2017, the transaction was finalised which meant that Rossoneri Sport Investment Lux became the new owner of the team. In order to conclude the agreement, American hedge fund Elliott Management Corporation provided Li with a loan amount of EUR303M (EUR180M to make the loan for Fininvest and EUR123M given directly to the club directly). On the 10th of July, the 10th of July, Li was unable to stay the loan payment schedule, failing to make a payment of EUR32 million at the time he was due to repay the EUR303 million loan debt that was owed by the American hedge fund. The result was that in July 2018, the chairman of Li Yonghong's investment vehicle Rossoneri Champion Inv. Lux. has been removed from the position of sole shareholder of Rossoneri Sport Inv. Lux., the direct parent company of the club. This makes the investment vehicle controlled by Elliott Management Corporation the sole shareholder of Rossoneri Sports Inv. Lux.
On the 27th of November, 2017 Montella was fired for poor performances and was replaced by the former teammate Gennaro Gattuso. Milan had qualified for to play in the season 2018-19 UEFA Europa League Group Stage following a 6th place finish on the table in the 2017-18 Serie A season, however, they were barred by UEFA from participating in European competition because of violations in the Financial Fair Play rules for failing to reach break-even. Milan challenged the decision of the Court of Arbitration for Sport and was ruled in favor of on the 20th of July, 2018.
In Gattuso's debut season as manager, Milan exceeded expectations and enjoyed a lot of time in the top four. Even though they won their final four matches, Milan missed out on the Champions League by 1 point and finished 5th with an average of 68 points. Following Milan's inability to be able to participate in this year's Champions League, Gattuso resigned as manager. On the 19th of June, 2019 Milan signed ex- Sampdoria director Marco Giampaolo on two-year contract. On the 28th of June, 2019 Milan had been excluded from participation in the 2019-20 UEFA Europa League for breaking Financial Fair Play regulations for the seasons 2014-2017 and 2015-2018.
After just four months as the manager, Giampaolo was sacked after losing four of his initial 7 games . This was caused by his poor performance and insecurity among the supporters. Stefano Pioli was appointed as his replacement. Following the return of Serie A campaign due to the COVID-19 outbreak, Milan went on a 10-match unbeaten streak and won 7 matches during the streak, including games with Juventus, Lazio and Roma. The streak resulted in Milan abstaining from employing the legendary Ralf Rangenick as the new sporting director and manager instead, and instead, Pioli was given a new contract for another two years. After a great start to the 2020-21 Serie A, which was an extension of the final season of the previous season and then a period that were inconsistent throughout the year, Milan under the leadership of Pioli in his debut season saw an overall second place finish in the league, which was the best finish of the squad since their 2012-2013 Serie A, where the team also placed second. their finish saw them get into their 2021-22 UEFA Champions League for the next season.
