If the government asked you to buy your own military gear based on the value of your house, you would be experiencing the medieval recruitment system. Between 1250 and 1500, warfare was completely dictated by the . Monarchs did not have the funds to maintain permanent forces, so they relied on the , which required knights to provide 40 days of unpaid military service in exchange for land.
By the 1400s, this rigid social structure began to evolve. The was largely replaced by , which were formal contracts paying captains to supply specific numbers of troops. At the same time, the social dominance of the mounted noble knight declined due to the deadly effectiveness of tightly packed infantry formations called and the rapid fire of the English longbow.
It might surprise you to learn that early firearms were actually less accurate and had a shorter range than the traditional English longbow. However, the introduction of gunpowder highlights a classic pattern of change: gradual evolution rather than an overnight revolution. Cannons first appeared in English armies around 1327, but handheld weapons slowly evolved over centuries from the clumsy to the , and finally the highly reliable in the 1690s.
The most significant turning point in this era was the creation of the in 1645. Unlike the temporary medieval levies, this was Britain's first permanent, professional .
Crucially, it operated on meritocracy rather than social hierarchy, meaning officers were promoted based on battlefield skill rather than noble birth. By 1689, public fear of this military power led to the , which legally prevented the monarch from keeping a in peacetime without Parliament's permission.
You can clearly see the impact of technology in everyday life, but in the 19th century, factories and telegraphs completely rewrote the rules of warfare. The Industrial Revolution allowed weapons to be mass-produced using stronger, cheaper steel thanks to the .
A regiment of 800 infantrymen upgrades from muzzle-loading to rifles. Calculate the difference in the total number of rounds the regiment can fire in one minute. (Assume a muzzle-loader fires 3 rounds per minute and a breech-loader fires 11 rounds per minute).
Step 1: Calculate the total firepower of the old weapons.
Step 2: Calculate the total firepower of the new weapons.
Step 3: Find the difference.
Alongside factory growth, Britain experienced a , becoming the first predominantly urban nation. Recruitment shifted from healthy rural farm workers to the urban poor seeking a steady wage.
However, many city recruits suffered from the —stunted growth and poor health caused by overcrowded, unsanitary slums. Following logistical disasters exposed by the newly invented electric telegraph during the Crimean War, the government introduced . A key feature of this was the , ensuring wealth could no longer buy command ranks.
Why does the creation of a national bank matter to military history? Because wars are ultimately won with money. In the medieval period, the King spent up to 100% of his income on warfare, but the total tax collected only represented about 1% to 2% of the country's overall wealth.
To fund massive, professional standing armies, Britain had to transform into a fiscal-military state. The establishment of the in 1694 allowed the government to borrow massive sums, creating the . By the 20th century, the incredible costs of total war meant the government had to extract far more wealth from society, introducing aggressive new direct taxes like the and expanding income tax to the working classes.
Students often confuse gradual evolution with rapid turning points; remember that the introduction of gunpowder was a slow evolution over centuries, whereas the creation of the New Model Army in 1645 was a sudden, dramatic turning point.
When answering 16-mark 'how far do you agree' questions on the process of change, always explicitly compare whether a change was driven by technology (e.g., the Bessemer Process) or by government attitudes (e.g., Cardwell's Reforms).
Examiners look for clear links between social structure and military composition; for top marks, explain how the demographic shift to cities directly forced the army to recruit from the urban poor.
If a question asks about continuity, you can argue that command of the army remained dominated by the wealthy upper classes from the medieval knights all the way until Cardwell's Reforms in 1871.
