French politician François-Pierre-Guillaume Guizot (1787–1874) is well-known for establishing 'Guizot's law', which implemented primary education for all French citizens. As well as occupying various political offices during some of the most turbulent years in his nation's political history, Guizot was also an historian and was appointed to the chair of modern history at the Sorbonne in 1812. First published between 1829 and 1832, this five-volume history of 'civilisation in France' is based on a series of lectures delivered in 1828. The books are described as covering the period from the end of the Roman Empire to 1789, but the main focus is on the medieval period, to the death of St Louis (1270). Volume 4 discusses the developing sense of national identity in France in the tenth century and ends with an examination of the monarchy and of feudal society at the death of Louis VII (1180).
