Sussex is a large county on the southeastern coast of England. Crowds of vacationers flock to its seaside towns in summer. Most of the people of Sussex live close to the coast. Many of these people make the trip to London daily to work. One of the most famous battles in British history was fought in Sussex, near the town of Hastings, in 1066. At this battle, Duke William of Normandy led the last successful invasion of England and became King William I (the Conqueror).
