During the First World War, theatrical performances and other forms of entertainment became increasingly important for the war effort both at home and abroad. In Britain, patriotic plays encouraged support for the war and helped recruitment drives. Concert parties and revues provided temporary distraction and boosted morale.

The theatre also provided a means of raising funds and supplies for servicemen. Some of the money raised was used to buy theatrical equipment for soldiers at the front. Instruments, costumes and props helped soldiers stage their own performances on the fighting fronts. Although concert parties and theatrical troupes were found on all fighting fronts, it was in France and Belgium that they were most numerous.

Organised entertainment was often of high standard, partly because many of the divisional concert parties included professional actors and others with experience working in theatre. By December 1914, 800 professional actors had volunteered for military service, and many more entered the armed forces after conscription was introduced in 1916. Servicemen also enjoyed more amateur performances by individual performers such as comedians and ventriloquists.

These performances were one of the few forms of amusement or recreation available to soldiers. They reminded them of life before the war and of those dearest to them at home. They also helped maintain morale and provided temporary comfort amidst the often difficult and dangerous conditions of the front.
