William the Conqueror

Following the Battle of Hastings, William the Conqueror marched on London, to Southwark and failed to get across London Bridge or to defeat the Londoners. He eventually crossed the River Thames at Wallingford, pillaging the land as he went. Rather than continuing the war, Edgar Ætheling, Edwin of Mercia and Morcar of Northumbria surrendered at Berkhamsted. William rewarded London in granting the citizens a charter in 1075; the City of London was one of the few institutions where the English retained some authority.
