In A History of Ancient Britain, much-loved historian Neil Oliver turns a spotlight on the very beginnings of the story of Britain; on the first people to occupy these islands and their battle for survival. There has been human habitation in Britain, regularly interrupted by Ice Ages, for the best part of a million years. The last retreat of the glaciers 12,000 years ago brought a new and warmer age and with it, one of the greatest tsunamis recorded on Earth which struck the north-east of Britain, devastating the population and flooding the low-lying plains of what is now the North Sea. The resulting island became, in time, home to a diverse range of cultures and peoples who have left behind them some of the most extraordinary and enigmatic monuments in the world. Through what is revealed by the artefacts of the past, Neil Oliver weaves the epic story  half a million years of human history up to the departure of the Roman Empire in the Fifth Century AD. It was a period which accounts for more than ninety-nine per cent of humankind's presence on these islands.
