The Nature and Impact of Medieval Warfare

Worked Example

How did the 1381 Poll Tax impact an ordinary peasant family? (Given: The 1381 Poll Tax was a flat rate of 4 groats, or 12d, per person over 15. An unskilled labourer earned roughly 1d per day.)

Step 1: Identify the tax burden per person.

• $\text{Tax per person} = 12\text{d}$

Step 2: Calculate the days of labour required to pay for one person.

• $12\text{d} \div 1\text{d/day} = 12 \text{ days}$

Step 3: Evaluate the economic impact.

• A single peasant would have to work for nearly two full weeks just to pay the tax for one family member, directly contributing to the outbreak of the Peasants' Revolt in 1381.

The Destructive Impact of Warfare on Civilians

In medieval conflicts, full-scale battles between armies were incredibly rare; instead, commanders deliberately targeted the civilian population to ruin the enemy's economy.

• English armies in France frequently used the Chevauchée tactic—rapid, scorched-earth cavalry raids designed to burn crops, mills, and towns, completely destroying the rural economic backbone of the enemy.
• Domestically, English civilians suffered greatly from Purveyance, the Crown's legal right to forcibly purchase food and horses at a low, appraised price, often paying only with wooden IOUs (tallies).
• The logistical burden of moving large armies was devastating to local areas. An army of 20,000 men could exhaust the total food and fuel supplies of a 2,000-person town in just one or two days.
• Furthermore, when soldiers' wages were delayed, armies often resorted to illegal Plundering, stealing civilian goods and spreading terror as they "lived off the land."
• The domestic impact was so severe that intense social unrest forced the government to pass the Statute of 1362, which heavily restricted purveyance for military logistics.

Fortifications and Economic Benefits of War

Understanding the sheer scale of medieval armies explains why some towns actually grew richer during periods of intense conflict.

• Large armies waiting to embark for France created massive demand for food, leather, and weapons. This stimulated local trade in coastal Garrison Towns like Southampton and Portsmouth.
• Troops often spent their wages or French plunder in local markets, providing a "trickle-down" economic boost to these regions.
• The threat of raids led to heavy investment in Point Defense. While kings spent vast sums on royal castles (like Edward I's Iron Ring), local towns relied on Murage grants to fund their own stone walls.
• Following devastating French raids, towns like Rye were granted a Licence to Crenellate, allowing them to build secure town walls that protected civilians and ultimately increased local property values.
• In conclusion, the impact of war on populations was highly polarized. While rural communities and foreign populations suffered catastrophic physical and economic destruction from raiding and purveyance, fortified coastal towns frequently experienced economic stimulation and long-term civic investment.
