[3] The new club established their first headquarters in the Roma coffeehouse located on the similarly named town square in Monza;[1] the team initially wore a blue and white kit.

[8] Monza first participated in the Terza Categoria [it] (third level) in the 1913–14 season [it]; they played their first match on 4 January 1914,[9] losing 3–1 at home against Fanfulla.

[18] In 1919, Monza hosted the Czechoslovakia military national team[19] for a friendly game at Grazie Vecchie field that ended in a 1–1 draw.

[20] Their first game was played on 24 October 1920, a 4–1 home defeat to Milan; Francesco Mandelli scored Monza's lone goal.

[23] Due to a restructuring of the league system, Monza were moved to the Seconda Divisione (second level) for the 1922–23 season;[24] they avoided relegation by beating Chiasso and Canottieri Lecco in the play-offs.

[41] Against most experts' pre-season expectations, Monza finished the 1952–53 Serie B in fourth position, three points behind automatic promotion in second place.

[48] Despite Monza's stable financial situation,[b] no one was interested in purchasing the club; Sada decided to remain president for the following season.

[53] After winning the 1966–67 play-off game against Como 1–0, thanks to a lone goal by Gianluigi Maggioni [it] in the 32nd minute, Monza were promoted back to the Serie B after one year.

[59] Five matches before the end of the 1975–76 season, Monza were promoted back to the Serie B;[60] they also won an Anglo-Italian Cup on 19 June 1976, beating Wimbledon 1–0 in the final through a Francesco Casagrande [it] goal.

[67] In Cappelletti's last season as president, in 1979–80, Monza failed to gain promotion to the top flight for the fourth consecutive year.

[76] In the 1986–87 Serie C1 [it], players such as Alessandro Costacurta, Francesco Antonioli and Pierluigi Casiraghi, who later became established names in Italian football, made their professional debuts with Monza.

[92] The following season, newly promoted Monza changed most of their roster, introducing young players, many of whom came from Milan's youth sector.

[94] In April 1999,[91] after 19 years of presidency, Giambelli left the club amid criticism from fans concerning Monza's close connection with Milan and their CEO Adriano Galliani.

[100] On 3 June the same year, the club was acquired by Atalanta vice-president Gian Battista Begnini,[101] who renamed it AC Monza Brianza 1912.

[106] On 13 July 2009, Begnini sold the club to the PaSport holding company, headed by former Milan player Clarence Seedorf.

[115] In May 2016, the club changed its name to SS Monza 1912 and achieved promotion back to the Serie C under coach Marco Zaffaroni in 2017.

[119] According to Forbes's 2021 ranking, Berlusconi was the richest owner of a football club in Italy, and ninth worldwide, with his fortune being valued at $7.6 billion.

[126] On 8 June, the Italian Football Federation formally declared Monza champions and the team were promoted to the Serie B after a 19-year absence from the competition.

[28] The change came as a result of professor Giuseppe Riva's report addressed to the comune of Monza in May 1923, in which he discovered that the city's historical colours were red and white.

[150] In 1971, Monza's home kit underwent a slight but significant change: a vertical white band was added on the left-hand side, running through the length of the red shirt.

[154] On 22 August 1979, during a 1979–80 Coppa Italia game against Milan, Monza displayed the players' names on top of the numbers on the back, a novelty at the time dubbed "all'Americana" (American style); the Italian Football Federation did not approve of the change and fined the club.

[158] On their 110th anniversary on 1 September 2022, Monza introduced a light blue kit as their third colours for the 2022–23 season in honour of the club's first shirt.

[161] In 1933, the badge became circular and was vertically divided into red and white halves, and included golden initials ACM with the crown at the bottom.

[162] It stayed the same until 1945, following World War II, when it changed to a rectangular shape that was divided into red and white halves.

[163] Following Monza's promotion to the Serie B in 1951, the crest again became oval shaped and the text's orientation was changed from vertical to horizontal.

[164] This design lasted five years until Monza's merger with Simmenthal, when the logo became more detailed; the badge was shaped like an ox head, including the horns.

[169] The logo remained until 2004, when a new crest was introduced: it was a more rounded red shield with white details; "AC Monza Brianza" was written on top, and a depiction of a sword "cutting through" a crown – both drawn in a minimalist style – was placed on the bottom.

A modified version of the logo was announced to mark the occasion: a gold crown with red and white gems was placed on top of the crest.

[186] Monza re-opened the east stand – which had been closed for 20 years – ahead of the 2022–23 Serie A season,[187] bringing the maximum seating capacity from 10,000 to about 17,000.

[191] Following Berlusconi's takeover of the club in 2018, attendance figures started to rise and new supporter groups began to emerge.
