Following a dispute between two parties in AC Milan, a batch of Swiss and Italian players broke away to form Internazionale Milano or Inter Milan in 1908. The name of the club was derived from their purpose to allow international as well Italian players within their ranks. The club chose blue and black as their Colors, earning them the nickname Nerazzurri, which means ‘black and blue’ in Italian. In 1910, the club won its first championship within two years of its formation.

Initially, Inter played its home matches at Arena Civica. In 1926, the first game at San Siro was played between arch rivals Milan and Inter which the latter won 6-3. However, back then San Siro was only AC Milan’s home ground. It wasn’t until 1947 that Inter shifted to San Siro, sharing the stadium with rivals Milan.

Inter Ultra fans are usually termed as right-wing in contrast to Milan ultras. Boys San has been one of the oldest ultra-groups of Inter. The Nerazzurri are considered the second most supported club in Italy. The no. 3 and no. 4 kits will never be worn by any of future players as they were retired in honour of defenders Giacinto Facchetti and Javier Zanetti. The club has won 18 Serie As, 7 Coppa Italias, 3 European Cups and 2 Intercontinental Cups.
