Invasions of Britain

There are six particular historical moments to concern us here, starting with the migration of Indo-European peoples from their origins in southern Russia. The five subsequent movements involve the invasion of Britain and the mixture of languages which the invaders brought with them go to make up that mongrel language modern English.

The main reasons for the historical invasions of Britain were:
the country was large compared to the power of their civilization
the country was rich in fertile land and materials
the country was an island fairly central to other areas
the invaders' populations were growing and they needed space for new settlements
the country was popular with many tribes and the first to capture it would have a large and well positioned stronghold over their enemies
the invaders had the technology to take over.
