The name of the town was first recorded as "Byllyrica" in 1291.
The urban settlement, which was within the manor and parish of Great Burstead, was one of many founded in the late 13th century in an already densely populated rural landscape.
Billericay's most notable historical episode was the Battle of Billericay during the Peasants' Revolt of 1381. Four local people (Thomas Watts, Joan Hornes, Elizabeth Thackwell, and Margaret Ellis) were burnt at the stake.
Two other residents (Joan Potter and James Harris) were tortured for their faith during the reign of Queen Mary.
Some of them may have spent the night in Billericay before crossing the River Thames at Tilbury.
This may account for the large number of inns in the town.
Several suggestions for the origin of the place name include: The Tudor antiquarian John Leland believed the already-abandoned Billerica in Kent was a variant of Bellocastrum, ‘fair castle’ in Latin.
In Billericay there is a Roman fort at Blunt’s Wall Farm; likewise ‘Burh’ gives is name to Great Burstead.
Some of the earliest records of human occupation of Billericay are the burial mounds in Norsey Wood: evidence of occupation in the Bronze and Iron Ages.
