This is the story of two queens - Elizabeth I the consummate politician and Mary Queen of Scots the Catholic mother. It is also the story of the birth of a nation.

There is no saga more powerful than that of the warring dynasty - domineering father, beautiful, scheming mother and squabbling, murderous sons and daughters, (particularly the nieces). In the years that followed the Norman Conquest, this was the drama played out on the stage of British history.

1066 is not the best remembered date in British history for nothing. In the space of nine hours whilst the Battle of Hastings raged, everything changed. Anglo-Saxon England became Norman and, for the next 300 years, its fate was decided by dynasties of French rulers.

Nations is the epic account of how the nations of Britain emerged from under the hammer of England's "Longshanks" King Edward I, with a sense of who and what they were, which endures to this day.

Here Simon Schama charts the upheaval caused as a country renowned for its piety, whose king styled himself Defender of the Faith, turns into one of the most aggressive proponents of the new Protestant faith.

Simon Schama starts his story in the Stone Age village of Skara Brae, Orkney. Over the next four thousand years Romans, Anglo-Saxons, Vikings and Christian missionaries arrive, fight, settle and leave their mark on what will become the nations of Britain.

In the aftermath of Civil War, Britain was a kingless republic led by Oliver Cromwell. Cromwell ruled with an iron hand; when Parliament dared defy him, he marched in and closed it down. He ruled as king in all but name, with his Major Generals imposing Godly Puritan rule on the counties. The anarchy that prevailed at his death led to the Restoration of Charles II, who survived the Great Fire and a dynastic crisis triggered by anti-Catholic paranoia. James II's Catholic fervour threatened to trigger another revolution; he was deposed by the troops of the Dutch King William.

How did a people who thought themselves free end up subjugating so much of the world, a nation with such a distrust of armies become the greatest military power on Earth, an empire of the free become an empire of slaves?Britons took the flag across the globe and created an empire built on ambition and slavery, exploration and daring. Trade flourished in the addictive commodities of tea, sugar and coffee, as did the deplorable trade in people. Taxation lost Britain the American colonies, but paved the way for dominance in India, as tax gatherers became administrators and merchants, emperors. The Wrong Empire is the exhilarating and terrible story of how one small group of islands came to dominate the world; a story of exploration and daring, but also one of exploitation and conflict.

It took only six years for the plague to ravage the British Isles. Its impact was to last for generations. But from the ashes of this trauma an unexpected and unique class of Englishman emerged.

The turbulent civil wars of the early seventeenth century would culminate in two events unique to British history; the public execution of a king and the creation of a republic. Schama tells of the brutal war that tore the country in half and created a new Britain - divided by politics and religion and dominated by the first truly modern army, fighting for ideology, not individual leaders.

In 1690s England, the victors of the Glorious Revolution celebrated the dawn of a new era under a new king - William III. In Scotland, the Jacobites still supported the deposed King James II and the country suffered crippling poverty and famine.Relations between Scotland and England were tainted by the Glencoe Massacre in 1692 and Westminster's strategy to scupper the Darien venture. Half a century later, however, the two countries were forging a partnership, based on profit and interest, which evolved into the Act of Union in 1707.

Britain never had the kind of revolution France experienced in 1789, but came close to it. This programme explains how 'the romantic generation' discovered the politics of sympathy with the common man. Nature was turned into a revolutionary idea by radicals and poets like Thomas Paine and William Wordsworth, and events across the channel following the fall of the Bastille initially seemed to point a way forward for Britain. But when the terrifying reality of the French Revolution set in, nature was recruited by the patriots.

Queen Victoria came to the throne at the tender age of eighteen, to rule over a country in the throes of a painful but supercharged industrial transformation. Chaos and revolution had been predicted by both socialists and traditionalists but in fact family life provided a bedrock of stability. This is how Britain's women, from the Queen to Chartist charladies and West Indian nurses managed the intense change and attempted to galvanize social reform for their Victorian sisters.

The British Empire promised peace, stability and prosperity but in Ireland and India it coincided with violence and famine. The programme examines the origins of agonies which continue to resonate today, and how political justice failed to feature in the administration of the time. As Victorian prime ministers, Gladstone and Disraeli promoted very different visions of Empire, but despite their lofty ideals, Schama observes how 'common humanity was sacrificed to the fetish of the market'.

Schama's last programme is a meditation on the place of the past in Britain's 20th-century history. Personified in the sharply different reactions of two of its greatest figures, Winston Churchill and George Orwell, the programme explores the fate of the country through two world wars, the slump and a nervous postwar peace. What was the impact of the crusades and the protests of the century, and did Winston Smith, hero of Orwell's 1984, foresee the contemporary political landscape?
