Professor Robert Bartlett explores the Plantagenets, England's longest ruling dynasty, in this version of the BBC Two series made especially for schools. Fifteen of the nation's most famous and infamous kings came from this one family. Their story is one of intrigue, conflict and brutality, but during their 331-year domination of England they shaped the country's politics and culture. Bartlett reveals how Parliament was born, the system of justice was established through Magna Carta and the foundations of the United Kingdom were set down. Ultimately, the family tore itself apart and was destroyed through civil war.
