This week Neil MacGregor's history of the world is looking at how the global economy became cemented in the 19th century, a time of mass production and mass consumption. He tells the story of how tea became the defining national drink in Britain - why have we become so closely associated with a brew made from leaves mainly grown in China and India? The object he has chosen to reflect this curious history is an early Victorian tea set, made in Staffordshire and perfectly familiar to all of us. The historian Celina Fox and Monique Simmonds from Kew gardens find new meaning in the ubiquitous cuppa.

Neil MacGregor's history of the world as told through things. Throughout this week he is examining the global economy of the 19th century - of mass production and mass consumption. Today he is with an instrument that first helped Europeans to navigate with precision around the world - a marine chronometer. The one Neil has chosen actually accompanied Darwin on his great voyage to South America and the Galapagos Islands - a journey that was to help lead him to his revolutionary theories on evolution.

Neil MacGregor's world history told through the things that time has left behind. Throughout this week, Neil has been looking at Europe's discoveries around the world and its engagement with different cultures during the 18th century - the European Enlightenment project.

Today he describes what was happening in China during this period, as the country was experiencing its own Enlightenment under the Qianlong Emperor. He tells the story through a jade disc (called a Bi) that was probably made around 1500 BC and then written over by the Emperor himself. What does this prehistoric piece of jade tell us about life in 18th century China and how they explored their past? The historian Jonathan Spence and the poet Yang Lian find meaning in this intriguing object.

The history of humanity as told through one hundred objects from the British Museum in London. This week, Neil MacGregor, the Director of the Museum, is looking at Europe's engagement with the rest of the world during the 18th century.

Today he is with an object "freighted with layers of history, legend, global politics and race relations". It is a shield from Australia, originally owned by one of the men to first set eyes on Europeans as they descended on Botany Bay nearly 250 years ago. This remarkably well-preserved object was brought to England by the explorer Captain Cook. What can this object tell us about the early encounter between two such different cultures? Phil Gordon, the aboriginal Heritage Officer at the Australian Museum in Sydney, and the historian Maria Nugent help tell the story.

The history of humanity - as told through one hundred objects from the British Museum in London - is once again in North America. This week, Neil MacGregor, the museum's director, is looking at Europe's engagement with the rest of the world in the 18th century.

Today he tells the story of a map, roughly drawn on deerskin that was used as the colonists negotiated for land in the area between the Great Lakes and the Mississippi. It was probably drawn up by a Native American around 1774. Neil looks at how the French and the British were in conflict in the region, and examines the different attitudes to land and living between Europeans and Native Americans. Martin Lewis, an expert on maps from this region, and the historian David Edmunds describe the map and the clash of cultures that was played out within its boundaries.

This week Neil MacGregor's history of the world is telling the story of European encounters across the globe during the 18th century.

Today he finds out what happened to Captain Cook as he was mapping and collecting in the Pacific. Neil tells the story through a chieftain's helmet made from a myriad of colourful bird feathers that was given to Cook when he landed in Hawaii in 1778. This is not a story with a happy ending. The anthropologist Nicholas Thomas and the Hawaiian academics Marques Hanalei Marzan, Kyle Nakanelua and Kaholokula help describe Cook's impact in the Pacific and the meaning of the feathered helmet.

Neil MacGregor's history of the world as told through things that time has left behind. Throughout this week, he is examining the often troubled relationship between Europe and the rest of the world during the 18th century.

Today he tells the extraordinary story of a now fragile African drum. It was taken to America during the years of the slave trade and where it came into contact with Native Americans. The drum was brought to England by Sir Hans Sloane, whose collection became the British Museum in 1753. This drum, the earliest African-American object in the Museum, is a rare surviving example of an instrument whose music was to profoundly influence American culture - bought to America on a slave ship and transported to Britain by a slave owner. The historian Anthony Appiah and the writer Bonnie Greer consider the impact of this drum.

Neil MacGregor's world history as told through things that time has left behind. This week Neil is looking at the co-existence of faiths - peaceful or otherwise - across the globe around 400 years ago. So far he has looked at objects from India and Central America, Iran and Indonesia that embody the political consequences of belief. Today he is back in Europe, with a document that marks an anniversary and that is designed to raise morale. It's a woodblock print, a broadsheet, commissioned in Saxony in 1617 to mark a hundred years of the Protestant Reformation and anti-Catholic sentiment. Neil describes the broadsheet and the uncertain Protestant world that produced it. Was this the first time that an anniversary was commemorated in this way, with a kind of souvenir? The broadcaster and journalist Ian Hislop considers the broadsheet as an early equivalent to the tabloid press while the religious historian Karen Armstrong describes the reforming motivation that the broadsheet celebrates.

The history of humanity as told through one hundred objects from the British Museum in London. This week Neil MacGregor is looking at the co-existence of faiths - peaceful or otherwise - across the globe around 400 years ago. Today he is with a document that shows what happened after Catholic Spain's conquest of Mexico - it's an old map, or codex, that was made at the height of the Spanish church building boom in Mexico. Neil uses the object to consider the nature of the Spanish conquest and to explore what happened when Catholic beliefs were assimilated alongside older pagan beliefs. The historian Samuel Edgerton offers an interpretation of the map that shows churches alongside older temples, and the Mexican born historian Fernando Cervantes considers the ongoing legacy of the great Christian conversion.

The history of humanity - as told through one hundred objects from the British Museum in London - is in South East Asia. This week Neil MacGregor, the museum's director, is with the objects from across the world around 400 years ago that explore the relationships between religion and society. Today he is with a shadow puppet from the Indonesian island of Java, asking how a puppet watched by a predominantly Muslim audience is a character from a Hindi epic. He describes the history of the theatre of shadows and explores how it reveals the religious traditions that have shaped Indonesian life. He talks to a puppet master from Java. And the Malaysian novelist Tash Aw discusses the influence of shadow theatre on the region today.
