Revolutionary Symbols are symbols, that represent certains eras and have revolutionised due to societies views on them.
For example the southern cross is a constellation of stars in the sky, but is replicated on the Australian flag, and symbolises Australian heritage. But in modern times, it is not un common for Australians who take strong pride in there culture to get the southern cross tattooed onto themselves. It was widely re-known amongst a particular group of Australians known as the Bra-Boys to represent themselves with this tattoo.
