From their small county in the heart of France, the lords of Anjou - the Angevins - produced dynasties that became kings of Jerusalem, England, Sicily, Hungary and Poland from 900 - 1500. They were described by a contemporary as ''lords of the greatest part of the world''. Here is their extraordinary story, including figures such as Geoffrey Plantagenet, Empress Matilda, Eleanor of Acquitaine, Charles of Anjou, Queen Johanna of Naples, Louis the Great of Hungary and Saint Jadwiga of Poland.
