A landmark series for Channel Four UK to mark the 100th anniversary of the foundation of the House of Windsor. Exclusive access to the Royal Archives at Windsor Castle make this series a truly unique, historical and unprecedented TV series. No cameras have ever been allowed into Her Majesty's archive until now... It is one hundred years since July 1917 when the British King, His Majesty George V, changed his family's name from Saxe-Coburg Gotha, the name of the King's German Grandfather, Prince Albert, to the quintessentially British Windsor . This six-part series reveals the reasons for the endurance of the House of Windsor through six key events, some obviously major ones, weddings, funerals etc., others seemingly run of the mill, but which provide clues to the longevity of the House of Windsor. Adapt or Die This episode reveals fresh insights into how George V rescued the monarchy by dumping his family's German roots, and explores the Edward VIII abdication crisis. Love and Duty In 1947, as Britain suffers from crippling post-war austerity and the worst winter on record, a lovesick Princess Elizabeth and her ailing father, George VI, visit South Africa on a fraught royal tour. Enter the Outsider This episode reveals how Prince Philip was the Windsors' most radical moderniser, and how in the 1960s he harnessed the medium of television to revamp the royals' public image. Shadow of a King Prince Charles tries to avoid replicating Edward VIII's romantic mistakes, while Lord Mountbatten acts as Charles' kingmaker and matchmaker. Fire, Feud and Fury This episode examines the huge challenge that Diana's popularity and tragic death posed to the royal family. The Top Job Prince Charles is the most outspoken heir to the throne in the Windsors' history and has promised a radically different vision for the monarchy. But will his reign make or break the Windsor dynasty?
