When war broke out in 1914, millions of men eagerly signed up to fight, but within two years, the government had to force them to join. The First World War began with a reliance on volunteers, driven by Lord Kitchener's famous recruitment campaign. Many joined Pals Battalions, serving alongside friends and colleagues from their local towns.
However, by 1916, voluntary enlistment could not replace the massive casualties. The government introduced Conscription through the Military Service Acts. The Jan 1916 Act forced single men aged 18 to 41 to join; this was extended to married men in May 1916 and later to older age groups up to 51 in 1918.
During the Second World War, conscription was implemented immediately in 1939 for men aged 18 to 41. However, the government exempted men in Reserved Occupations, such as miners and farmers, because their labour was vital to keeping the country running. After WWII, Britain introduced peacetime National Service (1948–1963), requiring young men to serve up to two years. This eventually ended because maintaining a mass conscripted army became too expensive and ill-suited for modern, high-tech warfare.
You cannot run a modern, high-tech military using thousands of untrained civilians with rifles. Historically, Britain shifted toward a professional Standing Army with the New Model Army in the 17th century, and later through the 19th-century Cardwell Reforms. These reforms abolished the purchase of officer ranks, creating a Meritocracy where promotion was based on skill rather than wealth.
Training methods have also transformed dramatically. In the 19th century, drill focused on linear formations on the parade ground to instil strict obedience and discipline. Today, training is a highly structured, two-phase process.
First, recruits complete Phase 1 Training, a 13-week course focused on physical fitness, core values, and basic weapon handling. Following this, soldiers undergo Phase 2 Trade Training, where they learn highly technical specialisations across over 100 roles, such as bomb disposal or logistics. Modern training has also shifted away from harsh physical punishments, moving towards a coaching and mentorship model to develop skilled technicians.
For centuries, women were largely unofficial camp followers, but the demands of 20th-century warfare transformed them into essential military personnel. During the First World War, over 100,000 women served voluntarily in Auxiliary roles, training at major hubs like Tidworth on Salisbury Plain.
The Second World War marked a radical structural change. From December 1941, unmarried women aged 20 to 30 were officially conscripted into the military or vital industry. Their roles expanded beyond cooking and transport into highly technical fields, such as radar operation and mechanics, with extensive training at camps like Cowdray Park.
When male National Service ended in 1960, the military faced a severe Manpower Gap. To solve this, the permanent WRAC (Women's Royal Army Corps) was expanded. Women trained at Queen Elizabeth Park in Guildford and served in over 40 specialized trades, freeing up men for frontline duties. By 2018, all close combat and infantry roles were finally opened to women, completing their full integration into the armed forces.
Modern warfare does not just happen on distant battlefields; it transforms the daily lives of the people left behind. The 20th century saw the rise of Total War, where the entire civilian population and economy were mobilised to support the war effort. During WWII, the Home Front became a target; the Blitz (1940–41) killed over 40,000 civilians, while many people were displaced through Evacuation. Daily life was transformed by Rationing, which ensured the fair distribution of food during naval blockades.
This total mobilisation heavily impacted the treatment of the Conscientious Objector (CO). During WWI, COs faced harsh, punitive treatment. Absolutists, who refused any war-related work, were subjected to solitary confinement and hard labour. This brutality was designed to deter others and maintain public support for the war.
By WWII, the government adopted a more lenient, pragmatic approach. Special tribunals still judged the sincerity of COs, but the majority were Alternativists who were assigned vital civilian work, such as forestry and farming. This softer approach was actively used to contrast British democratic freedoms with the tyranny of Nazi Germany.
During the Cold War, the development of atomic weapons shifted civilian anxieties away from conventional bombing campaigns to the existential dread of Mutually Assured Destruction (MAD). The famous 4-Minute Warning before a missile impact left the public feeling like permanent, helpless targets. Unlike WWII, where the RAF could defend the skies, there was no effective defense against nuclear annihilation.
The government attempted to manage this fear with "Protect and Survive" propaganda booklets (1980), instructing civilians on how to build makeshift fallout rooms. However, many citizens rejected these measures and protested instead. The Campaign for Nuclear Disarmament (CND), formed in 1957, demanded Unilateral Disarmament, organising massive demonstrations like the Aldermaston Marches to protest Britain being used as a front-line nuclear base.
To Evaluate the transformative nature of war, we must weigh the physical reality of Total War against the psychological threat of the Cold War.
Governments have historically relied on Propaganda to boost public morale and encourage recruitment, while simultaneously using Censorship to restrict information that might cause panic.
During WWI, the government used the Defence of the Realm Act (DORA) to legally censor letters from the trenches. Meanwhile, propaganda films like The Battle of the Somme (1916) were released to millions to justify high casualty rates. In WWII, the Ministry of Information tightly controlled the narrative with campaigns like "Dig for Victory," whilst newspaper editors practiced self-censorship.
Conversely, independent war reporting has frequently shifted public attitudes. During the Crimean War, William Howard Russell's reports in The Times exposed leadership failures, directly leading to the collapse of the government. In the 21st century, the 2003 Iraq War saw 24-hour news cycles and embedded journalists broadcast the chaotic reality of insurgency, rapidly eroding public support for the initial "Mission Accomplished" narrative.
Students often state that women were conscripted in both World Wars. Remember that women volunteered in WWI and were only formally conscripted from December 1941 during WWII.
In 12-mark or 16-mark 'Evaluate' questions, compare the physical impact of WWII (The Blitz, Rationing) against the psychological impact of the Cold War (Nuclear anxiety). Examiners want to see a balanced judgement on which threat was more 'transformative' to daily life.
Examiners award specific knowledge marks for linking the end of National Service (1963) to the modern need for highly skilled, professional specialists rather than a mass infantry.
When evaluating the treatment of Conscientious Objectors, secure higher marks by comparing the harsh, punitive approach of WWI with the more pragmatic, lenient civilian work assigned in WWII.
