It's one of the darkest murder mysteries in British history: did Richard III really kill his nephews in order to make himself king? Is he the greatest villain in English history, or the victim of centuries of grotesquely unfair Tudor propaganda? On the eve of Richard's reburial at Leicester Cathedral, this drama documentary assembles a stellar cast of experts, including David Starkey and Philippa Gregory, to examine all the available evidence. As it plays out the possibilities and tests the competing theories, it endeavors to get to the bottom, once and for all, of what really happened to the princes in the Tower. Is this a tale of naked ambition, cold pragmatism and bloody murder?

Writers and historians including Hilary Mantel and Philippa Gregory revisit the last days of Anne Boleyn, who in 1536 became the first queen in British history to be executed.

In the middle of the 17th century, Britain was devastated by a civil war that divided the nation into two tribes - the Roundheads and the Cavaliers. In this programme, celebrities and historians reveal that modern Britain is still defined by the battle between the two tribes. The Cavaliers represent a Britain of panache, pleasure and individuality. They are confronted by the Roundheads, who stand for modesty, discipline, equality and state intervention. The ideas which emerged 350 years ago shaped our democracy, civil liberties and constitution. They also create a cultural divide that influences how we live, what we wear and even what we eat and drink. Individuals usually identify with one tribe or the other, but sometimes they need some elements of the enemy's identity.
