August 1st is 'Yorkshire Day' - to promote the historic English county.
It was celebrated in 1975, by the Yorkshire Ridings Society, initially in Beverley, as a protest movement against the Local Government re-organisation of 1974. The date alludes to the Battle of Minden (1759) and it is also the anniversary of the emancipation of slaves in the British Empire in 1834, for which a Yorkshire MP, William Wilberforce, had campaigned.
