The Sheffield and Hallamshire Football Association (originally called the Sheffield Football Association) was formed in Sheffield in 1867 and was the first County Football Association in England. Its teams adopted the Sheffield Rules of football up until 1878 when they were merged with The Football Association's rules. Its members include some of the oldest football clubs in the world, such as Sheffield and Hallam. Today, the County FA is responsible for the administration, control, promotion and development of grass-roots football within Sheffield, Doncaster, Rotherham, Barnsley, Worksop and Huddersfield.
