Iron Age hill forts: tribal kingdoms, farming, art and culture

Welcome to the Iron Age in Britain!

Hello and welcome to your history study guide! Today, we are travelling back in time to explore the Iron Age in Britain. We will discover giant hilltop forts, circular homes, clever new tools, Celtic art, and powerful tribal rulers.

Don't worry if all the names and dates seem tricky at first. We will break everything down step-by-step with helpful tips along the way!

What Was the Iron Age?

The Iron Age in Britain lasted from about 800 BC to AD 43. It ended in AD 43 when the Romans invaded Britain.

The Iron Age is part of prehistory. Prehistory means the long period of time before people began writing down records of their history.

Top Tip: The change from the Bronze Age to the Iron Age did not happen overnight! It was a slow and gradual process that took place at different times across different parts of Britain.

Key Takeaway: The Iron Age in Britain lasted from around 800 BC to AD 43 (ending with the Roman invasion) and is part of prehistory because there were no written records yet.

1. Hill Forts and Roundhouses

During the Iron Age, people built impressive hilltop settlements called hill forts. Let's look at how they were made and what life was like inside them.

What is a Hill Fort?

A hill fort is a defended village built high up on a hill. It was protected by giant earth banks and walls called ramparts, as well as deep ditches carved into the ground.

• Ramparts: Protective banks or walls made of earth, stone, or timber (wood).
• Ditches: Deep trenches dug around the ramparts to make it very hard for enemies to climb up.

Here are three famous Iron Age hill forts you should know:
• Maiden Castle in Dorset
• Danebury in Hampshire
• Castell Henllys in Wales

Why Were Hill Forts Built?

The word fort makes us think of battles, but historians believe hill forts had many different purposes:

• Defence: A safe place to protect people and animals from attackers.
• Showing Off: A way for powerful chiefs to show off their wealth and high status.
• Gathering Places: Busy centres for trading goods and holding religious ceremonies.

Life Inside the Roundhouse

Inside a hill fort, families lived in circular homes called roundhouses. Inside the fort walls, you would also find workshops, granaries (special buildings raised on stilts to store grain and keep it dry), and fenced areas for livestock.

How was a roundhouse built?
• Walls: Made of wattle and daub. Wattle is woven wooden sticks (like a giant wicker basket), and daub is a sticky mix of mud, clay, and animal dung smeared over the top to keep out the wind and rain.
• Roof: A conical, thatched roof made of straw or reeds with a smoke hole or gaps to let smoke out from the central cooking fire.

Key Takeaway: Hill forts were protected by ramparts and ditches. People lived in wattle-and-daub roundhouses and used hill forts for defence, trade, religion, and showing off their status.

2. Farming and Inventions

Why was iron so special? Iron was much harder, stronger, and sharper than bronze! Because iron was so tough, it allowed people to make far better farming tools.

New Inventions in the Iron Age

• Iron-Tipped Ploughs: Ploughs tipped with hard iron could cut through heavy, clay-rich soil that bronze tools could not easily manage. This made farming much faster and produced more food.
• Sharper Iron Axes: Helped farmers clear forests quickly to make room for growing crops and grazing animals.
• The Rotary Quern: A clever invention made of two circular stones. Grain was poured in, and the top stone was turned by hand to grind the grain into flour much more quickly than older, flat grinding stones.
• The Potter's Wheel: Allowed craftspeople to shape clay pots smoothly and quickly.

Key Takeaway: Iron tools were stronger than bronze. Inventions like iron-tipped ploughs, the rotary quern, and the potter's wheel made farming and daily work much more efficient.

3. Tribal Kingdoms, Art, and Culture

Iron Age Britain was not ruled by one single leader. Instead, Britain was divided into different regions called tribal kingdoms.

Tribes and Rulers

Each tribe was led by a king or queen. For example, a famous king named Cunobelin ruled over a powerful tribe called the Catuvellauni in southeastern Britain.

Celtic Art

Iron Age craftspeople were very skilled artists! Their art style is easy to recognise:
• Shapes and Patterns: Iron Age art was full of flowing curves, circles, and spirals. (This was very different from the straight lines and sharp angles used later by the Romans!)
• Decorated Items: They decorated metal mirrors, shields, helmets, and jewellery with these swirling patterns.

The Torc: A Symbol of Power

A torc was a large, stiff neck ring made of twisted strands of metal, often made from shiny bronze or pure gold. Wearing a torc showed everybody that you were a person of very high status and importance in the tribe.

Key Takeaway: Britain was split into tribal kingdoms ruled by kings (like Cunobelin) or queens. Iron Age art loved spirals and curves, and powerful nobles wore twisted metal neck rings called torcs.

4. Trade and the First Coins

Did you know? Iron Age Britons were not cut off from the rest of the world. They were busy traders who were well-connected to mainland Europe!

Trading with Europe

Britons traded across the sea with nearby lands like Gaul (modern-day France):
• What Britain Imported (bought in): Wine and delicate glassware.
• What Britain Exported (sold out): Grain, hunting dogs, and slaves.

From Bartering to Coins

For most of prehistory, people used a system called bartering. Bartering means swapping goods directly (for example, swapping three sheep for a sack of grain).

However, between around 120 BC and 100 BC, something brand new arrived in Britain: coins!
• This was the very first time money was ever used in Britain.
• The first coins were imported from Gaul (modern France), and later, British tribes began minting (making) their own coins, often inspired by Roman designs.

Key Takeaway: Britain was connected to Europe through trade. Between 120 BC and 100 BC, Britain moved from bartering (swapping items) to using coins for the very first time.

5. Common Mistakes to Avoid

• Mistake 1: "The Iron Age started in a single day."
Fact: Moving from bronze to iron was a gradual process that spread across Britain slowly over time.

• Mistake 2: "Hill forts were only used for fighting."
Fact: Hill forts were also used to show off high status, to live in, to trade, and to hold religious gatherings.

• Mistake 3: "Iron Age Britons lived completely alone with no contact with other countries."
Fact: They traded actively with mainland Europe, importing luxury goods like wine and glass.

• Mistake 4: "People have always used coins for money."
Fact: Before coins arrived around 120–100 BC, Britons only bartered by swapping goods.
