The Razor Gang Wars were a series of violent conflicts in Australia during the 1920s and 1930s, primarily in Sydney. These clashes involved rival criminal groups, known as razor gangs, who fought for control over illegal activities such as gambling and drug trafficking. The gangs were notorious for their use of razors as weapons, leading to brutal confrontations and a significant rise in crime rates. Key figures in the Razor Gang Wars included notorious criminals like Freddie "The Fox" Brown and Kate Leigh, who were prominent gang leaders. The violence drew public attention and prompted law enforcement to take action, ultimately leading to increased police presence and efforts to curb organized crime in the region.
