The concept of 'plantation' is explored in this programme, yet presenter Niall Ferguson is not referring to crops but the settlement of British people into the colonies. Without this mass white emigration there would have been no empire. Visiting Northern Ireland, the USA and Australia, we explore how the first colonies of the British empire developed.

In contrast to the Spanish, the British viewed the colonies as a way to gain land to settle on and use, rather than just conquest and plunder. The east coast of the USA was first settled by puritans wanting religious freedom, including those who sailed on the famous ship 'The Mayflower' in 1620. The combination of cheap land and abundant natural resources made this an ideal location for sugar and tobacco plantations. Niall goes on to describe the American War of Independence a century and a half later.

Following the religious revival that started in the late 18th century, missionaries began working in Africa and India in an attempt to bring Christianity and civilisation to societies perceived as heathens. We learn of David Livingstone's adventures in Africa as he attempted to link the three 'C's – Christianity, commerce and civilisation. From his discovery of the Victoria Falls to his famous meeting with Henry Stanley, we follow the career of this fascinating character.

Presenter Niall Ferguson also travels to India and examines the changing attitudes towards Indian religions and culture during the 19th century. He also traces the Indian mutiny of 1857 and its brutal aftermath in which thousands were brutally killed.

In this programme we discover how a few thousand British people ruled over India, a country of more than 250 million people and the centre point of the whole British empire. Niall Ferguson demonstrates the vital role played by the Indian army both within India and beyond, and the role of British technology in developing the army and modern Indian cities. Modern-day footage of the hill station at Simla gives us a glimpse of colonial life in late 19th century India.

From the early 19th century an elite class of well-educated Indians was encouraged, with men like JN Bose becoming successful lawyers and administrators. In fact, the British administrators were so few in number that it was essential to involve Indian people in their own government. Yet by the end of the 19th century the White Mutiny threatened to end this liberal attitude and ultimately led to a genuine Nationalist movement.

The 'Scramble for Africa' by competing European nations during the last years of Queen Victoria's reign is the compelling tale of this programme. We learn how 10,000 independent African kingdoms became 40 European colonies over the course of two decades, in a drastic redrawing of the map. Indeed, by 1900 Britain owned half of Africa.

No longer dominated by moral and religious concerns, this new era was about power and the economy as the battle for raw materials progressed. Power was in the hands of bankers and industrialists such as Rothschild and Cecil Rhodes, as illustrated by their use of the new Maxim guns to keep any opponents in check. By this stage it was businessmen doing the colonising and not governments.

The fall of the British empire is usually attributed to Nationalist groups fighting for independence, yet as Niall Ferguson argues in this final programme of the series, it was really due to the crippling cost of running the empire and financing the two World Wars. He reflects on the achievements and problems of the empire and concludes that in its twilight years Britain did more good than harm in fighting two far worse empires, namely Japan and Germany. Visiting some of the hot spots of the two World Wars and of the campaigns for independence that followed, such as Gallipoli, Istanbul, Suez, Amritsar and Singapore, presenter Niall Ferguson gives us a vivid picture of an empire on its last legs.
