Two Football clubs located in the same Scottish city are hosts to one to one of the deepest cultural sporting rivalrys we have ever seen.  you might not of heard of them but Celtic and Rangers are the two most successful clubs in the Scottish league sharing a total of  105 league championships and 46 Scottish Cups. These clubs bring in what is close to be 120 million pounds for the scottish economy, but the cultural impact of these teams is what truly is interesting. As both of these clubs were started roughly between 1870-1885, both their fanbases were almost predertimined by religion.  Rangers FC developed a Protastant fanbase that also shared the same cultual views of being British and Loyalists, while Celtic fans were Catholic and embraced their Irish Scot identity.  This rivalery has developed as time has gone on and the cultural impact has carried on for hundreds of years.  When the teams meet today it is known as the "Old Firm Derby"  because just like seeing a old freind, you will always give a firm handshake.
