If you ask a room full of historians for a list of Britain kings, you’re going to get an argument. It sounds like it should be simple. It isn't. People usually want a neat line of succession starting with some guy in a crown and ending with King Charles III. But Britain didn't even exist as a unified concept for most of human history. For centuries, you had "Kings of the West Saxons" or "Kings of the Mercians" beating the living daylights out of each other over muddy fields.
The truth is messy.
Alfred the Great is the name everyone knows, but he wasn't technically the King of England. He was the King of the West Saxons. He just happened to be the one who stopped the Vikings from deleting English culture entirely. It wasn't until his grandson Athelstan came along in 927 AD that we actually got something resembling a unified monarch. Even then, the "list" is full of usurpers, teenagers who disappeared in towers, and a few people who didn't even speak English.
The Early Mess: Before England Was England
Before we get into the heavy hitters, we have to acknowledge the heptarchy. This was a collection of seven kingdoms: Northumbria, Mercia, East Anglia, Essex, Kent, Sussex, and Wessex. Every single one of them had their own "list" of kings. If you were living in 750 AD, you didn't care about a "King of Britain." You cared about whether the King of Mercia was going to burn your barn down.
Offa of Mercia was a big deal. He built a massive dyke—literally a giant dirt wall—to keep the Welsh out. He even called himself "King of the English" on some coins, but it didn't stick. The Vikings changed everything. By the time the Great Heathen Army was done, Wessex was the only kingdom left standing.
The House of Wessex (The Real Starting Point)
Most modern lists start with Athelstan. He’s the first one to truly claim the title Rex Anglorum. Before him, his father Edward the Elder and his grandfather Alfred laid the groundwork.
Athelstan was a bit of a legend. In 937 AD, he fought the Battle of Brunanburh. It’s a battle most people haven't heard of, but it’s basically the "founding moment" of England. He crushed a coalition of Scots, Vikings, and Strathclyde Britons. If he’d lost, the map of the UK would look completely different today. After him came a string of kings with names that sound like IKEA furniture: Edmund the Magnificent, Eadred, and Eadwig.
Then came Edgar the Peaceful. He was "crowned" at Bath in 973, setting the template for the coronation ceremony we still use today. It’s wild to think that when Charles III was crowned, he was following a script written over a thousand years ago.
The Viking Interruption and the Norman Reset
Everything went sideways with Ethelred the Unready. His name is actually a pun—"Ethelred" means "noble counsel" and "Unready" (Unræd) means "no counsel." Basically, Noble Counsel had No Counsel. He was a disaster. He paid the Vikings to go away (Danegeld), which, surprise, just made them come back for more.
This led to Cnut the Great.

Cnut was a Danish prince who became King of England, Denmark, and Norway. He’s the guy who famously sat in his chair by the tide to prove to his flattering courtiers that he couldn't actually control the ocean. He was surprisingly good at being a king. He kept the peace, respected the church, and didn't treat England like a conquered province.
Then we get to 1066. The big one.
William the Conqueror and the End of Anglo-Saxon Rule
Edward the Confessor died without an heir. Harold Godwinson took the throne, but William of Normandy claimed Edward had promised it to him. They fought it out at Hastings. Harold took an arrow to the eye (maybe), and William changed the list of Britain kings forever.
The Normans didn't just take over; they rebuilt the country. They built the Tower of London. They wrote the Domesday Book, which was basically the world's most aggressive tax audit. After William came:
- William II (Rufus): He was hated and died in a "hunting accident" that was almost certainly a murder.
- Henry I: He had about 20 illegitimate children but only one legitimate son who died in a shipwreck.
- Stephen and Matilda: They spent years fighting a civil war called The Anarchy. It was a brutal time when "Christ and his saints slept."
The Plantagenets: High Drama and Long Reigns
If you like Game of Thrones, the Plantagenets are your people. This is where the list gets really bloody. Henry II was a genius who accidentally had the Archbishop of Canterbury murdered. His son, Richard the Lionheart, spent only about six months of his ten-year reign in England because he was too busy fighting crusades.
Then there was John. Poor, terrible King John. He lost Normandy, argued with the Pope, and was forced by his barons to sign the Magna Carta in 1215. He’s the reason no British king has been named John since.
The Edwards and the Richards
The list continues through the 1200s and 1300s with some heavyweights:
- Edward I (Longshanks): The "Hammer of the Scots." A terrifyingly effective military leader.
- Edward II: Not so effective. He was eventually deposed and allegedly murdered with a red-hot poker.
- Edward III: Started the Hundred Years' War and lived long enough to see his kingdom ravaged by the Black Death.
- Richard II: A child king who grew up to be a tyrant and was eventually overthrown by his cousin, Henry Bolingbroke.
This brings us to the House of Lancaster and the House of York. The Wars of the Roses. It wasn't a constant war; it was more like decades of sporadic, extremely violent family reunions. Henry V was the hero of Agincourt, but his son Henry VI was mentally ill and couldn't hold the throne. This led to Edward IV, the brief reign of the boy-king Edward V, and the infamous Richard III.
The Tudors: The List Becomes Iconic
Henry VII won the crown in the dirt at Bosworth Field. He was a bit of a bean-counter, but he was exactly what the country needed after years of civil war. Then came his son, Henry VIII.

You know the story. Six wives. Broke with Rome. Dissolved the monasteries. Henry changed the "list" because he essentially created the Church of England to get a divorce. His children followed:
- Edward VI: The sickly boy king who pushed radical Protestantism.
- Mary I: "Bloody Mary." She tried to turn the country back to Catholicism and burned a lot of people at the stake in the process.
- Elizabeth I: The Virgin Queen. She reigned for 45 years, defeated the Spanish Armada, and oversaw a golden age of literature. But she had no kids.
When Elizabeth died in 1603, the Tudor line ended. This is a massive turning point because the crown went to her cousin, James VI of Scotland.
The Stuarts and the "United" Kingdom
James I (and VI) was the first to call himself "King of Great Britain." He wanted to unite the kingdoms, but it wasn't official yet. His son, Charles I, is the only person on the list of Britain kings to be legally executed by his own people.
The English Civil War led to a period where there was no king at all—the Interregnum under Oliver Cromwell. It was a bleak time where Christmas was basically cancelled. People hated it so much that they invited Charles II back in 1660.
The Stuart line eventually gave way to the House of Hanover because the English Parliament decided they’d rather have a distant German cousin who was Protestant than a close Catholic relative.
The Hanoverians and the Victorians
The Georges (I, II, III, and IV) oversaw the rise of the British Empire. George III is the one who lost the American colonies and struggled with mental illness. Then came William IV, and finally, Victoria.
Victoria’s reign lasted 63 years. She saw Britain transform from an agrarian society to an industrial powerhouse. When she died in 1901, the "list" shifted to the House of Saxe-Coburg and Gotha, which her son Edward VII changed to the House of Windsor during World War I because sounding German was a bad look.
The Modern Era: Windsors and the Commonwealth
The 20th century was a whirlwind for the monarchy. Edward VIII abdicated the throne because he wanted to marry an American divorcee, Wallis Simpson. This thrust his brother, George VI—the reluctant, stuttering king—into the spotlight during World War II.
Then we have Elizabeth II.

She is the longest-reigning monarch in British history, serving from 1952 to 2022. She saw 15 Prime Ministers, from Winston Churchill to Liz Truss. Her death marked the end of an era that most people alive today had never known anything else.
Now, we have Charles III.
What Most People Get Wrong About the List
One of the biggest misconceptions is that the "King of England" is the same thing as the "King of Britain." It isn't. The Acts of Union in 1707 officially joined England and Scotland into Great Britain. Before that, you had two separate lists that just happened to share the same person starting in 1603.
Another weird quirk: Lady Jane Grey. Some people put her on the list (she reigned for nine days), while others skip her entirely because she was never crowned. The same goes for Louis of France, who was actually proclaimed King in London in 1216 but usually gets ignored because history is written by the winners.
Practical Steps for History Buffs
If you’re trying to memorize this or just understand it better, don't try to learn every name at once. It's too much. Instead, break it down by the "Great Shifts":
- The Unification (927–1066): Focus on Athelstan and Cnut.
- The Norman/Plantagenet Era (1066–1485): This is the time of castles, knights, and the Magna Carta.
- The Tudor/Stuart Transition (1485–1714): Religion, the Renaissance, and the Civil War.
- The Modern Imperial Era (1714–Present): The Georges, Victoria, and the Windsors.
To really see this history in person, skip the standard tourist traps for a second. Go to St. George's Chapel at Windsor. It holds the remains of Henry VIII, Charles I, and Elizabeth II. It’s the most condensed physical version of the list of Britain kings you’ll ever find. If you’re in London, the Westminster Abbey floor plan is essentially a chronological map of royal history.
Understanding the monarchy isn't about memorizing dates for a test. It’s about seeing how a small island went from a collection of warring tribes to a global empire, and how the people wearing the crown were often just as confused and flawed as the people they ruled.
