In Our Time: History Folgen

Jane Francis, Richard Corfield and Carrie Lear join Melvyn Bragg to discuss ice ages, periods when a reduction in the surface temperature of the Earth has resulted in ice sheets at the Poles. Although the term 'ice age' is commonly associated with prehistoric eras when much of northern Europe was covered in ice, we are in fact currently in an ice age which began up to 40 million years ago. Geological evidence indicates that there have been several in the Earth's history, although their precise cause is not known. Ice ages have had profound effects on the geography and biology of our planet.With:Jane Francis Professor of Paleoclimatology at the University of LeedsRichard Corfield Visiting Research Fellow in the Department of Earth Sciences at Oxford UniversityCarrie Lear Senior Lecturer in Palaeoceanography at Cardiff University.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the War of 1812, the conflict between America and the British Empire sometimes referred to as the second American War of Independence. In June 1812, President James Madison declared war on Britain, angered by the restrictions Britain had imposed on American trade, the Royal Navy's capture of American sailors and British support for Native Americans. After three years of largely inconclusive fighting, the conflict finally came to an end with the Treaty of Ghent which, among other things, helped to hasten the abolition of the global slave trade. Although the War of 1812 is often overlooked, historians say it had a profound effect on the USA and Canada's sense of national identity, confirming the USA as an independent country. America's national anthem, The Star-Spangled Banner began life as a poem written after its author, Francis Scott Key, witnessed the British bombardment of Fort McHenry during the Battle of Baltimore. The war also led to Native Americans losing hundreds of thousands of acres of land in a programme of forced removal.

Melvyn Bragg and his guests discuss The South Sea Bubble, the speculation mania in early 18th-century England which ended in the financial ruin of many of its investors. The South Sea Company was founded in 1711 with a view to restructuring government debt and restoring public credit. The company would ostensibly trade with South America, hence its name; and indeed, it did trade in slaves for the Spanish market even after the Bubble burst in 1720. People from all walks of life bought shares in the South Sea Company, from servants to gentry, and it was said the entire country was gripped by South Sea speculation mania. When the shares crashed and the company collapsed there was a public outcry and many people faced financial ruin, although some investors sold before the crash and made substantial amounts of money. For example, the bookseller Thomas Guy made his fortune and founded a hospital in his name the following year. But how did such a financial crisis develop and were there any lessons learnt following this early example of a stock market boom and bust?With:Anne Murphy Senior Lecturer in History at the University of HertfordshireHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonRoey Sweet Head of the School of History at the University of LeicesterProducer: Natalia Fernandez.
