The club was founded on March 9, 1908, following a schism from the Milan Cricket and Football Club, now known as A.C. Milan. A group of Italians and Swiss (Giorgio Muggiani, a painter who also designed the club's logo, Bossard, Lana, Bertoloni, De Olma, Enrico Hintermann, Arturo Hintermann, Carlo Hintermann, Pietro Dell'Oro, Ugo and Hans Rietmann, Voelkel, Maner, Wipf, and Carlo Ardussi) were unhappy about the domination of Italians in the AC Milan team, and broke away from them, leading to the creation of Internazionale. From the beginning, the club was open to foreign players and thus lived up to her founding name. The original nickname of the team was bauscia, the braggarts.

The club won its very first scudetto (championship) in 1910 and its second in 1920. The captain and coach of the first scudetto was Virgilio Fossati, who was killed in World War I. Its first Coppa Italia (Italian Cup) was won in 1938-39, led by the great Giuseppe Meazza, for whom the San Siro stadium is officially named, and a fifth league championship followed in 1940, despite an injury to Meazza. During the Fascist era, the name "Internazionale" was not looked upon kindly, and the club played as Ambrosiana, wearing white shirts emblazoned with a red cross. In 1932, the club was permitted to append its old moniker, and was known as Ambrosiana-Inter. Finally in 1942, the club reverted to its original name, Internazionale.

Following the war, Inter won its sixth championship in 1953 and the seventh in 1954. Following these titles, Inter was to enter the best years of its history, affectionately known as the era of La Grande Inter (The Great Inter). During this magnificent period, with Helenio Herrera as head coach, the club won 3 league championships in 1963, 1965 and 1966. The most famous moments during this decade also include Inter's 2 back-to-back European Cup wins. In 1964, Inter won the first of those tournaments, playing against the famous Spanish club Real Madrid. The next season, playing in their Following the golden era of the 1960s, Inter managed to win their eleventh league title in 1971 and their twelfth in 1980. Inter were defeated for the second time in five years in the final of the European Cup, going down 0-2 to Johan Cruijff's Ajax Amsterdam in 1972. During the 1970s and the 1980s, Inter also added two to its Coppa Italia tally, in 1977-78 and 1981-82.

In the 2004-05 season Inter won the Coppa Italia (Italian Cup) against AS Roma and followed that up by winning the Supercoppa Italiana (Italian Super Cup) against Juventus at the start of the 2005-06 season. On 11 May 2006, Inter retained their Coppa Italia title again against AS Roma, in a two legged match, with a result of 1-1 in Rome and 3-1 back home.

Inter was awarded the 2005-06 Serie A championship because of the match fixing scandal. The Italian Federal Appeal Commission on 14 July 2006 found Juventus, Lazio, Fiorentina and AC Milan guilty of match-fixing. Also, with the relegation of Juventus and the point deduction for AC Milan, Inter was immediately suspected to be the strongest favorite to finish in first for the 2006-07 Serie A season. During the season, Inter made a record 17-game winning streak in Serie A extending a new league record after having defeated Calcio Catania 2-5 on Feb. 25th. Inter bettered Real Madrid's and Bayern Munich's 15-match consecutive wins streaks. The run of consecutive wins ended on February 28, after a home 1-1 tie to Udinese Calcio.
