The Saxon Shore was a military command of the Late Roman Empire, consisting of a series of fortifications on both sides of the Channel. It was established in the late 3rd century and was led by the "Count of the Saxon Shore". In the late 4th century, his functions were limited to Britain, while the fortifications in Gaul were established as separate commands. Several well-preserved Saxon Shore forts survive in east and south-east England.

Roman Britain was the territory that became the Roman province of Britannia after the Roman conquest of Britain, consisting of a large part of the island of Great Britain. The occupation lasted from AD 43 to AD 410.
