Harold Godwinson in the context of "Bayeux Cathedral"

Edward the Confessor (c. 1003 – 5 January 1066) was King of the English from 1042 until his death in 1066. He was the last reigning monarch of the House of Wessex.

Edward was the son of Æthelred the Unready and Emma of Normandy. He succeeded Cnut the Great's son – and his own half-brother – Harthacnut. He restored the rule of the House of Wessex after the period of Danish rule since Cnut conquered England in 1016. When Edward died in 1066, he was succeeded by his brother-in-law Harold Godwinson, who was defeated and killed in the same year at the Battle of Hastings by the Normans under William the Conqueror. Edward's young great-nephew Edgar Ætheling of the House of Wessex was proclaimed king after the Battle of Hastings, but was never crowned and was peacefully deposed after about eight weeks.

William the Conqueror (c. 1028 – 9 September 1087), sometimes called William the Bastard, was the first Norman king of England (as William I), reigning from 1066 until his death. A descendant of Rollo, he was Duke of Normandy (as William II) from 1035 onward. By 1060, following a long struggle, his hold on Normandy was secure. In 1066, following the death of Edward the Confessor, William invaded England, leading a Franco-Norman army to victory over the Anglo-Saxon forces of Harold Godwinson at the Battle of Hastings, and suppressed subsequent English revolts in what has become known as the Norman Conquest. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands, and by difficulties with his eldest son, Robert Curthose.

William was the son of the unmarried Duke Robert I of Normandy and his mistress Herleva. His illegitimate status and youth caused some difficulties for him after he succeeded his father, as did the anarchy which plagued the first years of his rule. During his childhood and adolescence, members of the Norman aristocracy battled each other, both for control of the child duke, and for their own ends. In 1047, William quashed a rebellion and began 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 arrange the appointment of his supporters as bishops and abbots in the Norman church. His consolidation of power allowed him to expand his horizons, and he secured control of the neighbouring county of Maine by 1062.

The Norman Conquest of England (or the Conquest) was an 11th-century invasion by an army made up of thousands of Norman, French, Flemish, and Breton troops, all led by the Duke of Normandy, later styled William the Conqueror.

William's claim to the English throne derived from his familial relationship with the childless Anglo-Saxon king Edward the Confessor, who may have encouraged William's hopes for the throne. Edward died in January 1066 and was succeeded by his brother-in-law Harold Godwinson. The Norwegian king Harald Hardrada invaded northern England in September 1066 and was victorious at the Battle of Fulford on 20 September, but Godwinson's army defeated and killed Hardrada at the Battle of Stamford Bridge on 25 September. Three days later on 28 September, William's invasion force of thousands of men and hundreds of ships landed at Pevensey in Sussex in southern England. Harold marched south to oppose him, leaving a significant portion of his army in the north. Harold's army confronted William's invaders on 14 October at the Battle of Hastings. William's force defeated Harold, who was killed in the engagement, and William became king.

The Bayeux Tapestry is an embroidered cloth nearly 70 metres (230 feet) long and 50 centimetres (20 inches) tall that depicts the events leading up to the Norman Conquest of England in 1066, led by William, Duke of Normandy, challenging Harold II, King of England, and culminating in the Battle of Hastings. It is thought to date to the 11th century, within a few years of the battle. Now widely accepted to have been made in England, perhaps as a gift for William, it tells the story from the point of view of the conquering Normans and for centuries has been preserved in Normandy.

According to Sylvette Lemagnen, conservator of the tapestry, in her 2005 book La Tapisserie de Bayeux:

An overlord in the English feudal system was a lord of a manor who had subinfeudated a particular manor, estate or fee, to a tenant. The tenant thenceforth owed to the overlord one of a variety of services, usually military service or serjeanty, depending on which form of tenure (i.e. feudal tenancy contract) the estate was held under. The highest overlord of all, or lord paramount, was the monarch, who due to his ancestor William the Conqueror's personal conquest of the Kingdom of England, owned by inheritance from him all the land in England under allodial title and had no superior overlord, "holding from God and his sword", although certain monarchs, notably King John (1199–1216) purported to grant the Kingdom of England to Pope Innocent III, who would thus have become overlord to English monarchs.

A paramount lord may then be seen to occupy the apex of the feudal pyramid, or the root of the feudal tree, and such allodial title is also termed "radical title" (from Latin radix, root), "ultimate title" and "final title". William the Conqueror immediately set about granting tenancies on his newly won lands, in accordance with feudal principles. The monarch's immediate tenants were the tenants-in-chief, usually military magnates, who held the highest status in feudal society below the monarch. The tenants-in-chief usually held multiple manors or other estates from the monarch, often as feudal barons (or "barons by tenure") who owed their royal overlord an enhanced and onerous form of military service, and subinfeudated most to tenants, generally their own knights or military followers, keeping only a few in demesne. This created a mesne lord – tenant relationship. The knights in turn subinfeudated to their own tenants, creating a further subsidiary mesne lord – tenant relationship. Over the centuries for any single estate the process was in practice repeated numerous times.

The Battle of Hastings was fought on 14 October 1066 between the Norman-French army of William, Duke of Normandy, and an English army under the Anglo-Saxon King Harold Godwinson, beginning the Norman Conquest of England. It took place approximately 7 mi (11 km) northwest of Hastings, close to the present-day town of Battle, East Sussex, and was a decisive Norman victory.

The background to the battle was the death of the childless King Edward the Confessor in January 1066, which set up a succession struggle between several claimants to his throne. Harold was crowned king shortly after Edward's death but faced invasions by William, his own brother Tostig, and the Norwegian king Harald Hardrada (Harold III of Norway). Hardrada and Tostig defeated a hastily gathered army of Englishmen at the Battle of Fulford on 20 September 1066. They were in turn defeated by Harold at the Battle of Stamford Bridge on 25 September. The deaths of Tostig and Hardrada at Stamford Bridge left William as Harold's only serious opponent. While Harold and his forces were recovering, William landed his invasion forces in the south of England at Pevensey on 28 September and established a beachhead for his conquest of the kingdom. Harold was forced to march south swiftly, gathering forces as he went.

England in the Middle Ages concerns the history of England during the medieval period, from the end of the 5th century through to the start of the early modern period in 1485. When England emerged from the collapse of the Roman Empire, the economy was in tatters and many of the towns abandoned. After several centuries of Germanic immigration, new identities and cultures began to emerge, developing into kingdoms that competed for power. A rich artistic culture flourished under the Anglo-Saxons, producing epic poems such as Beowulf and sophisticated metalwork. The Anglo-Saxons converted to Christianity in the 7th century, and a network of monasteries and convents were built across England. In the 8th and 9th centuries, England faced fierce Viking attacks, and the fighting lasted for many decades. Eventually, Wessex was established as the most powerful kingdom and promoted the growth of an English identity. Despite repeated crises of succession and a Danish seizure of power at the start of the 11th century, it can also be argued that by the 1060s England was a powerful, centralised state with a strong military and successful economy.

The Norman invasion of England in 1066 led to the defeat and replacement of the Anglo-Saxon elite with Norman and French nobles and their supporters. William the Conqueror and his successors took over the existing state system, repressing local revolts and controlling the population through a network of castles. The new rulers introduced a feudal approach to governing England, eradicating the practice of slavery, but creating a much wider body of unfree labourers called serfs. The position of women in society changed as laws regarding land and lordship shifted. England's population more than doubled during the 12th and 13th centuries, fueling an expansion of the towns, cities, and trade, helped by warmer temperatures across Northern Europe. A new wave of monasteries and friaries was established while ecclesiastical reforms led to tensions between successive kings and archbishops. Despite developments in England's governance and legal system, infighting between the Anglo-Norman elite resulted in multiple civil wars and the loss of Normandy.

The Battle of Stamford Bridge (Old English: Gefeoht æt Stanfordbrycge) took place at the village of Stamford Bridge, East Riding of Yorkshire, in England, on 25 September 1066, between an English army under King Harold Godwinson and an invading Norwegian force led by King Harald Hardrada and the English king's brother Tostig Godwinson. After a bloody battle, both Hardrada and Tostig, along with most of the Norwegians, were killed. Although Harold Godwinson repelled the Norwegian invaders, his army was defeated by the Normans at Hastings less than three weeks later.

The battle has traditionally been presented as symbolising the end of the Viking Age, although major Scandinavian campaigns in Britain and Ireland occurred in the following decades, such as those of King Sweyn Estrithson of Denmark in 1069–1070 and King Magnus Barefoot of Norway in 1098 and 1102–1103.
