Ancient Britain — Stone Age to Roman departure

Two facts dominate the testable picture of ancient Britain. Caesar tried and failed in 55 BC. Claudius tried and succeeded in AD 43. Almost everything else in this section is texture around those two anchor dates.

Before the Romans

The handbook begins with stone-age and bronze-age arrivals, but the test only asks you to know the rough order, not exact dates. Useful “rounded” markers:

• About 10,000 years ago Britain stops being attached to continental Europe. The Channel forms.
• About 6,000 years ago the first farmers arrive. This is the period of Stonehenge — built as a stone-age monument, still the most visited prehistoric site in the country.
• About 4,000 years ago the Bronze Age begins.
• The Iron Age that follows is the era of Celtic-language tribes and the first British coins, which already carry the names of the kings who minted them.

You don’t need to memorise the exact sequence Stone → Bronze → Iron and the dates. You do need to know that Stonehenge is stone age, not Roman, and that Britain had coins before the Romans arrived.

The Romans, in two waves

55 BC — Julius Caesar invades and fails. Caesar’s expedition is the first written record of Britain. He withdraws. The handbook treats this as the first invasion attempt, not the conquest itself.

AD 43 — Emperor Claudius invades and stays. This is the conquest that produces “Roman Britain.” Resistance is stiff: Boudicca, queen of the Iceni tribe, leads the most famous revolt and is the figure to remember by name.

Two later landmarks in the Roman period are worth holding:

• AD 122 — Hadrian’s Wall is built across the north, intended to keep out the Picts of what is now Scotland. The wall is still there in pieces; it is one of the most-asked Roman-Britain facts.
• 3rd–4th centuries AD — the first Christian communities in Britain appear during the late Roman period. (Mass conversion comes later, after the Romans leave.)

AD 410 — Rome walks away

The single most important Roman-Britain fact is the date the Roman army leaves and never returns: AD 410. Rome is overstretched, the Empire is collapsing in the west, and Britain is at the very end of the line. The withdrawal is not a defeat; the Romans are simply pulled home and never come back.

This date is the anchor for everything that follows. The Anglo-Saxons fill the gap. The Christian re-conversion happens after, not before. The next time anyone successfully invades from outside is the Norman Conquest in 1066 — and even then, William of Normandy is the last successful invader, full stop.

Caesar (failed) → Claudius (succeeded) → Roman departure. Three beats. 55 BC, AD 43, AD 410. The first two are personal names; the last is just a year.

What to take from this chapter

1. 55 BC vs AD 43 — Caesar tried, Claudius did it. Don’t conflate them.
2. Boudicca is the named British resister. Iceni tribe.
3. Hadrian’s Wall, AD 122, against the Picts.
4. AD 410 is the Roman departure. Britain is then on its own until 1066.
5. Stonehenge is stone-age — pre-Roman, pre-everything testable.
