Why did Milan agree to share the same stadium with Inter Milan back then?

The current inter was in Mosolini's time in order to curry favor with Mosolini.

Changed the team to a different name (I forgot the specifics).

Moved the team out of the city of Milan.

Later Mosolini fell.

Inter is homeless.

Milan FC used it with Inter.

AC didn't have the money to buy a field international to lend to them

I don't know, but I know that AC has a lot more money than Inter in addition to being a stronger team.

I'm just now realizing that AC Milan fans aren't bad either!

Absolute Inter fans at home

Hehe.

The two Milan giants can share the economic benefits and convenience of sharing a stadium, and the two clubs can share the cost of running and maintaining the stadium without having to bear the high costs separately, so they share the same stadium.

Built in 1926, the San Siro Stadium was not originally the home of Inter, it was built by the then president of Milan, Mr. Pirelli, and belonged only to the Milan club.

Later, the city of Milan** bought the stadium, and the San Siro became the common home of both Milan teams. In the 80s, the name of the stadium was changed to Stadio Giuseppe Meazza in honor of the Italian superstar Meazza who played for both teams in Milan.

Although Meazza also played for AC Milan, he spent the peak of his career at Inter Milan, and AC Milan fans were reluctant to name their home stadium after an iconic figure of their sworn rivals, so AC Milan fans still refer to the stadium by its former name, "San Shen and Siro".

There is a clear distinction between the signs and logos inside and outside the stadium and the allocation of fan seats to ensure distinction and individuality between the two clubs. Therefore, sharing a stadium can be said to be the result of historical and practical considerations, as well as part of Milan's football culture.

Other teams that share the pitch together:

In Serie A, both Roma and Lazio have their home stadiums at the Stadio Olimpico, which they have been renting since 1953.

Similarly, Genoa and Sampdoria share the Luigi Ferrari Stadium, which has made it their home stadium since 1911, and Sampdoria who has played their home games at the stadium since 1946.

There are also examples of clubs sharing a stadium with the national team. In the Netherlands, both Ajax and the Dutch national team have made the Johan Cruyff Arena their home stadium, while AIK Solna and the Swedish national team have made the Friendship Arena in Stockholm their home stadium.

In the U.S., there were also examples of teams from different sports sharing the same stadium before Peixiao. The NFL's Seattle Seahawks share Century Connect Stadium with Major League Soccer's Seattle Sounders and NWSL's Lyon Monarchs. Meanwhile, Major League Baseball's New York Yankees share Yankee Stadium with New York City FC.
