IIRC, "Lucky" Luciano pulled some five families together to stop the warfare to make profits. After his death, the main families splintered off for various reasons and started up their warfare again.

Pretty much the gist of it.
Luciano brought the families together and showed them how they could make more money working together with a corporate structure. He was pretty much the Boss of Bosses with Myer Lansky as his right hand.
They made sure each of the families made bank on everything from bootleg hooch to prostitution to construction. The mob actually did a better job of running the cities than the government.
