The feudal world–generalization alert here–glorified warfare. Or at least the folks at the top did. Why wouldn’t they? They got to the top and they stayed there because they were armed and dangerous. If we want to explain their role nicely, it was to protect the country from invaders. If we’re not in a mood to be nice, the English aristocracy was there because they’d been the invaders, killing people and taking over what had once been theirs. And because they were too big and scary to get rid of–not that some of the Anglo-Saxons didn’t try.
But they were happy to fight any new invaders. And sometimes each other. And occasionally to be the invaders in other people’s lands.
Yes, if you didn’t mind a bit of bloodshed and you were born on the winning team, it was a fine old time to be alive.

Yet another relevant photo: Stained glass window with what I assume to be a knight in the centerfold. And if it’s not a knight (is that a halo behind him?), what the hell, he’s on a horse. Close enough. From Canterbury Cathedral.
The cult of knighthood
To be part of a class defined by warfare meant training from childhood. I’m leaning heavily here on Ian Mortimer’s book (remember books?) Medieval Horizons, and he writes about the aristocracy “deriving satisfaction” from war and “committing acts that caused enormous suffering but which they regarded as their right.”
They were enthusiastic enough about fighting that when they didn’t have a war at hand,they needed to be kept occupied, and raids were a good training ground for warfare–not to mention a good way to keep a restless set of knights amused. The English raided Wales and Scotland repeatedly, although the raids on Scotland seem to have been written up as invasions and the Scottish invasions as raids. That may be about numbers and it may be about nationalism, but the line between war and raid looks a bit blurry to me.
I’m less certain about Wales. Sorry.
When raids were out of season, restless aristocrats could always recreate war in the form of a joust, and in the earlier medieval period we’re not talking about the kind of fancified, one-on-one, controlled jousts we see in movies. Those came later. In 1341, Sir William Douglass (whoever he may have been) challenged the earl of Derby (he was the earl of Derby, that’s who he was) to a joust. The conditions were that no one wear armor and that they all fight with sharpened lances.
You’d do the same on a rainy Saturday when you’d gotten tired of listening to some damn minstrel plunk away on the lute. You know you would.
Twelve men fought on each side. Three were killed and there’s no record of how many were injured. The survivors agreed it was a great party and wrote very nice thank-you letters, saying, “Let’s do it again soon.”
The culture of chivalry, with its tales and songs and myths, glorified it all. It was all about personal courage, personal honor, personal strength.
From what I’ve found, serfs and associated non-nobles did get drafted into the wars the aristocrats started and commanded. They were foot soldiers, archers, and whatever else was needed. But they were the backup band, not the lead singers. The aristocracy hogged the spotlight.
Not to diminish that business of personal honor or anything, but real warfare, as opposed to jousts, could also be profitable. If you captured a knight (or–jackpot!–the king), you could hold him for ransom. It sounds like a board game, doesn’t it? I’ve seen references to ransoming archers as well, so commoners may have been ransomable, but the emphasis is pretty clearly on aristocrats, and the higher up the food chain the captive was, the bigger the ransom.
Historians argue about when and why that business of ransom began. It’s an interesting rabbit hole and we’re not going down it but you’re welcome to. Let me know when you get back and I’ll put the kettle on.
Another source of wartime profit was looting, and I’m not sure what more I can say about that. Soldiers took stuff, but to be fair, only when they could.
Attempts to rein in the brutality
A few winds blew in the direction of toning down the brutality of war. In the tenth century, the Peace of God movement–
Well, okay, not a lot is known about the Peace of God movement, but it started in southern France and popped up at assorted Church councils.
Back to the Peace of God movement, though. It was a response to the inability of, specifically, France’s Carolingian dynasty to impose anything like order, but more widely it was an effort to tone down the violence of the period. It urged combatants to make a distinction between soldiers (legitimate targets) and non-combatants. Warriors were not to commit rape and not to kill women, children, churchmen, or merchants.
A bit later, the Truce of God movement tried to ban fighting from sunset on a Wednesday until dawn on a Monday as well as during Lent and Advent, and if that strikes you as bizarre, think of it as a reminder of how different the medieval mindset was from the modern one. The ban parallels the restrictions on when a person could have sex or eat meat.
No, I didn’t make that up.
The Truce of God movement would’ve made perfect sense at the time, even to people who disagreed with it.
Two English kings, Edward III and Henry V, also tried setting some limits. Edward ordered that “no town or manor was to be burnt, no church or holy place sacked, and no old people, children, or women in his kingdom of France [France and England were hopelessly tangled at the time] were to be harmed or molested.” Henry’s ordinances instructed his soldiers to protect churches and religious buildings–not to steal from them; not to harm or capture clergymen and -women (or maybe that’s women and clergymen; Medieval Horizons’ wording leaves it open); not to take clergymen hostage unless they were armed and hostile; and not to rape any women.
The instructions are more interesting as an indication of what was happening than as a list of what they managed to stop. Still, warfare was changing, although not in the ways either movement hoped for.
The decline of the knight
Knights’ effectiveness depended on the massed charge, which could overwhelm a defense, but in the fourteenth century the knight started to lose his status as hero of the battlefield. In 1314, Robert the Bruce (Scotland; real person; also a movie that I remember as endless) scattered sharp metal gizmos–caltrops in case you care–across the ground English knights would have to charge across. He also had pits dug and planted them with sharpened stakes. He organized his men so that knights who got past the gizmos and the stakes charged their horses into a wall of pikes.
This sounds harder on the horses, who didn’t choose to be there, than on the knights–although to be fair a knight on his way to the ground wasn’t in an enviable position. But when the alternative is letting the knights kill you, you know how it is: a person’s ruthless side can come to the surface.
For our purposes, what matters is that knights charged foot soldiers and lost.
The English had longbowmen and might have won if they’d used them first, but they sent in the knights, in their full heroic cluelessness, and lost the battle.
Like the Scottish wall of pikes (and those sharp little gizmos, which would upset the balance of the sentence so let’s leave them out), the English longbow tipped battlefield power away from knights and toward ordinary soldiers. Longbowmen–commoners, remember, and beneath a knight’s notice–fought from a distance, in relative safety, and a wise commander let them decimate the enemy before turning the heroes on horses loose, even if doing so upset the social order.
By the end of the fifteenth century, armies had grown larger and knights no longer trained for a massed charge. Now it wasn’t just longbows and pikemen they’d be coming up against, but cannons. You couldn’t charge a cannonball and there was no heroism in getting splattered by one.
Regulating warfare
As the middle ages became middle aged and the structure of society changed, warfare needed a bit more justification. The papacy had become more powerful, so if one Christian king was going to fight another, he needed to justify it–if not to god at least to the Pope. That didn’t put an end to wars between Christian kings but it did boost everyone’s creativity by a factor of twelve.
But what really tamped things down was that war had become expensive, even with the countervailing lure of loot and ransoms. The side with more cannons and more soldiers was likely to win, and both cost money.
Money? In the early middle ages, it was around but it wasn’t central. In the 1150s, if you’d spread England’s supply of money evenly, everyone would’ve had 6 pence. By 1320 it would’ve been 10 shillings. (Twelve pence to the shilling. You’re welcome, and I had to look it up.) The shift to a money economy was underway. By the time we reach the later medieval period, warfare was measured in money–for arms, for soldiers, for all those little incidentals you forget to factor in at your peril. All that meant taxes, and in England it meant the king going to that ever-annoying Parliament, which had the power to approve or not approve some new tax to finance a new war.
That took some of the fun out of going to war.
And in the sixteenth century, after the War of the Roses went further and ruined the reputation of internecine warfare, Henry VII got rid of private armies by making it illegal for lords to keep supporters who wore their livery.
Translation? Every lord had his colors and symbols and assorted rigamarole. They dressed their followers to match. Think of it all as a uniform.
Building an army was now the prerogative of the king. Warfare had been nationalized.
Numbers
Wars in the early middle ages were likely to involve a few thousand men. Battle of Hastings, where the Normans took England? Seven thousand to eight thousand men on each side. Before 1300, most battles were much smaller. Sure, chroniclers wrote about armies of up to 80,000, but then I regularly claim to be a thousand years old. Don’t believe everything you read. Historians–those clever devils–look at the financial record to dig out more realistic numbers, and they say (or at least one says) it was rare to find more than 10,000 on a side.
By the sixteenth century–and by this time the middle ages isn’t just middle aged, it’s bald and has bad knees, if it’s still the middle ages at all–the English army had 30,000 men (do you really care where?). The Spanish had 200,000 and the French 80,000. And you can tell from the numbers that these weren’t drawn from the top of society. The top layer wasn’t big enough and didn’t see any glory in getting killed by cannonballs anyway. The percentage of noblemen dying of violence went from 25% in 1400 to 2.5% in 1750. Kings no longer risked their lives leading their troops. They delegated.
No two people agree on exactly when the middle ages ended, but for the sake of convenience let’s say it ends here.
