Timeline of conflict in Anglo-Saxon Britain facts for kids
The Timeline of Conflict in Anglo-Saxon Britain tells the story of battles and changes in power in Britain. This period starts just before the Roman Army left in the 4th century and ends shortly after the Norman Conquest in the 11th century.
Most of the information comes from old records called "annals" and writings by a famous monk named Venerable Bede. It's important to know that dates, especially from the 4th to the late 6th centuries, are often guesses. This is because there weren't many written records back then. Historians like Diana Greenway have called some old writers "weavers" of history, meaning they put together stories from different places. The Anglo-Saxon Chronicle, for example, was written to make Alfred the Great's family look good. So, while these old writings are helpful, we need to be careful with the exact dates, especially for the earliest times.
Understanding the Timeline
It's tricky to figure out the exact order of events in early Anglo-Saxon times. This is when the Anglo-Saxons started taking over land in Britain from the Romano-Britons (people who spoke Celtic, Latin, or both). The old records we have aren't always perfect, so it's hard to be super accurate.
For example, historians don't agree on the date of the famous Battle of Badon. Some say it was in 516, others 493, and some even earlier.
Much of what we know about dates comes from Bede (who lived from 672/673 to 735). In his book, Ecclesiastical History of the English People, Bede tried to figure out dates for early Anglo-Saxon events. Even though he mostly wrote about church history, Bede is seen as Britain's first true historian. He tried to list events by date and mentioned his sources. He used a lot of information from a 6th-century writer named Gildas, but Gildas wasn't always reliable with dates. Bede's work was very popular, and monks who wrote the different Anglo-Saxon Chronicles later used his dates.
Some stories say that Saxon warriors were invited to England to help fight off invaders from Scotland and Ireland. Another reason they might have come was that their own land often flooded, making it hard to grow food. So, they were looking for new places to live and farm.
The earliest dates in this timeline (from the 4th to the late 6th centuries) are the most debated. There are very few records from that time, so most of these dates were put together much later by people trying to write Anglo-Saxon history.
Here's a look at some events recorded in Bede's Ecclesiastical History, the Anglo-Saxon Chronicle, the Welsh Annals (Annales Cambriae), and Brut y Tywysogion. Remember, many dates from the 4th, 5th, and 6th centuries are still debated.
- AC = from the Annales Cambriae
- ASC = from the Anglo-Saxon Chronicle
- B = from Bede's writings
- ByT = from Brut y Tywysogion
- (?) = Dates and events that are debated or uncertain.
