An annual "International" sheepdog trial, has been held every year since 1906, with breaks only for the two World Wars and the 2001 Foot and Mouth outbreak. In 1922, National trials were set up in England, Scotland and Wales to find a national champion for each country and act as qualifying trials for the International trial. Ireland (comprising North, South and the Isle of Man) joined in 1961 to complete the set of four home nations.
