The Battle of Hastings occurred on 14 October 1066 during the Norman conquest of England, between the Norman-French army of Duke William II of Normandy and the English army under King Harold II. It took place at Senlac Hill, approximately 10 km (6¹⁄₄ miles) northwest of Hastings, close to the present-day town of Battle, East Sussex, and was a decisive Norman victory.

Harold II was killed in the battle—legend has it that he was shot through the eye with an arrow. He was the last English king to die in battle on English soil until Richard III was killed at the Battle of Bosworth Field. The battle marked the last successful foreign invasion of the British Isles. Although there was further English resistance, this battle is seen as the point at which William gained control of England, becoming its first Norman ruler as King William I.

The battle also established the superiority of the combined arms attack over an army predominately composed of infantry, demonstrating the effectiveness of archers, cavalry and infantry working cooperatively together. The dominance of cavalry forces over infantry would continue until the emergence of the longbow, and battles such as Crecy, Poitiers and Agincourt in the Hundred Years War.

Hastings is a town and borough in the county of East Sussex on the south coast of England. The town is located 24 mi (39 km) east of the county town of Lewes and 53 mi (85 km) south east of London, and has an estimated population of 86,900.

In historical terms, Hastings can claim fame through its connection with the Norman conquest of England; and also because it became one of the medieval Cinque Ports. Hastings was, for centuries, an important fishing port; although nowadays much reduced, it still has the largest beach-based fishing fleet in England. The town became a watering place in the 1760s, and then, with the coming of the railway, a seaside resort.

The attraction of Hastings as a tourist destination continues; although the number of hotels has decreased, it caters for wider tastes, being home to internationally-based cultural and sporting events, such as chess and running. It has set out to become "a modern European town" and seeks to attract commercial business in the many industrial sites round the borough.

William I (circa 1028 – 9 September 1087), also known as William the Conqueror or William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087. Descended from Viking raiders, he had been Duke of Normandy since 1035 under the name of William II. He faced a long struggle to establish his power when he became duke at the age of seven or eight, but by 1060 his hold over Normandy was secure.

William was the son of the unmarried Duke Robert the Magnificent of Normandy by his mistress Herleva. His illegitimate status and his youth caused some difficulties for him after he succeeded his father, as did the anarchy that plagued the first years of his rule. During his childhood and adolescence, the Norman aristocracy battled each other, both for control of the child duke and for their own ends. In 1047 William was able to quash a rebellion and begin to establish his authority over the duchy, a process that was not complete until about 1060. His marriage in the 1050s to Matilda of Flanders provided him with a powerful ally in the neighbouring county of Flanders. By the time of his marriage, William was able to secure the appointment of his supporters as bishops and abbots in the Norman church. His consolidation of power allowed him to expand his horizons, and by 1062 William was able to secure control of the neighbouring county of Maine.
