This is a wonderfully concise history of how England came to be unified under William the Conqueror from France. The history of England prior to William was one of many feudal manors and territories controlled by various lords who held power over their own territories. The former king, Edward, though a pious man, was unable to hold any kind of real control over the factions. At his death, Edward left no heir from his own marriage. William, a cousin of his, and one who Edward had made a promise to transfer the rule to, came from France to make sure that he followed up on that promise. He was the first man to be able to organize the country into a more unified country with a stronger central government.
