55 BC to 410 AD Julius Caesar invaded Britain in 55 BC, but the Britons, maintained political freedom and simply paid tribute to Rome until Claudius I conquered Britain in 43 AD. By 47 AD, Roman control stretched from south of the Humber River and east of the Severn River.
Colchester was their capital but London (Londinium) and Chester where important trading towns. In a strait line between these was built one of the most important Roman roads to convey Legions (troops) and goods around the conquered territory.
Although the road is Roman, the name Watling Street was provided later by the Anglo-Saxons. It maintained its status through the ages as an important route and to day it is known as the A5 for much of its length and within Milton Keynes (where the A5 has been diverted as a motorway style carriageway) Watling Street has become one of the city's Grid Roads.
