Before arriving in Britain, the Saxons lived in scattered tribal communities across the regions bordering the North Sea. These early Saxon societies were deeply connected to the land, relying on agriculture, fishing, and small-scale trade. Tribal loyalty and kinship bonds were essential elements of their social fabric, with chieftains and warrior elites guiding both domestic affairs and external conflicts. The Saxons were also known for their seafaring skills, which enabled them to raid and explore new territories across the English Channel.
The collapse of Roman authority in Britain during the fifth century created a power vacuum that attracted various opportunistic groups from the continent. The Saxons, along with other Germanic tribes, were invited initially by some British leaders as mercenaries to help defend against northern tribes. However, the relationship soon turned hostile, and what began as isolated settlements evolved into large-scale migrations and conquests. Over time, the Saxons established powerful kingdoms such as Wessex, Sussex, and Essex, which would become the foundation for the future English nation.
