Middlesex is a historic county, located in the southeastern part of England, bordering the city of London to the south. It was situated along the River Thames.
King Vortigern yielded Middlesex and other districts to the Saxons under Hengist in exchange for his life after Hengist captured him.
Middlesex | 0 to 800 AD
While Middlesex no longer exist as a distinct county, its historical legacy lives on in various ways, and it is remembered in historical records, literature, and local culture.
Roman Period | 1st – 5th centuries AD
During the Roman occupation of Britain, Middlesex was situated within the territory of the Catuvellauni tribe, an Iron Age Celtic tribe. Roman roads, including Watling Street, crossed through what is now Middlesex, connecting the Roman towns of Londinium (London) and Verulamium (St. Albans). The Romans established settlements and infrastructure in the region, leaving a lasting impact on the landscape.
Anglo-Saxon Settlement | 5th – 8th centuries AD
With the withdrawal of Roman forces from Britain in the early fifth century, Middlesex, like much of England, saw the influx of Anglo-Saxon settlers. The region was gradually settled by various Germanic tribes, including the Angles and Saxons. Middlesex likely saw the emergence of small Anglo-Saxon villages and communities during this period, although detailed historical records are limited.
Christianization | 6th – 7th centuries AD
The spread of Christianity reached Middlesex during the early medieval period. Christian missionaries played a role in converting the local population to Christianity. The establishment of churches and religious communities would have been a part of this process.
Viking Incursions | 8th century AD
In the late eighth century, Viking raids and incursions along the coast of England became a significant threat. These raids distrupted local communities and led to the construction of defensive structures in some areas.
