The Society was to embrace the counties of Down, Antrim, Armagh and Monaghan by holding Agricultural Shows and giving agricultural instruction.
In December 1903, the name was changed to the Ulster Agricultural Society, then in January 1904, His Majesty King Edward VII commanded that the Society be known as the Royal Ulster Agricultural Society. The Society has charitable status and its income is applied towards the promotion of its objectives.
