Professor Saul David uses the BBC archive to chart the history of the world's most destructive war, by chronicling how the story of the battle has changed. As new information has come to light, and forgotten stories are remembered, the history of World War Two evolves. The BBC has followed that evolution, and this programme examines the most important stories, and how our understanding of them has been re-defined since the war ended over 70 years ago.

Vanessa Collingridge examines the life of Elizabeth Tudor, with particular interest in how documentary television and the BBC has examined her legacy and interrogated her reign. Using Timewatch and other BBC archive stretching back over 60 years, Vanessa looks at her upbringing, her conflicts with her enemies including Mary, Queen of Scots, and her greatest victory against the Spanish Armada. The programme seeks to understand how Elizabeth I created a legacy that we still live with today, and examines how that legacy has changed over the centuries.

Historian Dr Thomas Asbridge explores the BBC's archive to reveal how television's telling of the Crusades has changed over the last 60 years. Using footage from Crusade documentaries shot during the Vietnam era, the Palestinian Crisis, the First Gulf War and the more recent War on Terror, he reveals how our interpretation of this medieval story has been influenced by modern political and social change. Thomas highlights the alternative Arabic perspectives on the Crusades, and asks whether this 1,000-year-old story really does cast its long shadow over the modern world, as so many have claimed. With contributions from Monty Python star and medievalist Terry Jones, Washington economist JK Galbraith, and historians Simon Sebag Montefiore, Dr Peter Frankopan, Prof Konrad Hirschler and Dr Fozia Bora.

Using 70 years of BBC history archive film, Professor Alice Roberts uncovers how the iconic ancient monument of Stonehenge has been interpreted, argued over and debated by some of Britain's leading historians and archaeologists. She reveals how new discoveries would discredit old theories, how astronomers and geologists became involved in the story and why, even after centuries of study, there's still no definitive answer to the mystery of Stonehenge.
