The West Riding Volunteer Regiment was formed during World War 1 for home defence purposes and consisted of more than 20 battalions. These volunteers guarded vital points such as railways and reservoirs as well as providing pre service training to men about to join the army.
They were eventually linked to Line Regiments in 1918 and were renumbered with the 1st, 16th, 17th and 18th Battalions becoming the 1st, 2nd, 3rd, 4th Volunteer Battalion York and Lancaster Regiment.
As well as the shoulder title to the 1 WRV, there were similar ones to the 16 WRV, 17 WRV and 18 WRV.
