Rangers were backed by the Catholics and Celtic the Protestants.
You might want to change this bit around or some Scottish person might kill you, on either side. Rangers were backed by the English and the protestants. Celtic were backed by the Irish and the catholics. The whole fued went back to the clubs origins and is rooted in history and wars between england, scotland and ireland. Some things go beyond the actual sport and just give people a place to voice their other issues.
Lol. Just made the change. I am sure I read it somewhere that it was the other way around. Thanks for that though as it is a big thing to some people.
