Battle of Hastings - England 14 October 1066

 One of the most influential conflicts in British history, the Battle of Hastings was a cataclysmic culmination of a war of succession, with three potential heirs to the English throne duking it out for control of the island nation.

Battle of Hastings
At the start of the war there were three competing for the throne, which Edward the Confessor had held till his death. These were Edward’s cousin, Duke William of Normandy; Harold Godwinson, the most powerful man in England; and the Norwegian Harald Hardrada, who was king of Norway and distantly related. These three rivals were soon reduced to two however, with Harold Godwinson defeating Harald Hardrada at the Battle of Stamford Bridge in Yorkshire, England, on 25 September 1066.
 
This defeat left just Duke William of Normandy and Harold Godwinson to battle it out for the title of king; in fact, Godwinson took the title prematurely after Stamford Bridge, believing that Edward had promised him the throne before his death, despite his closer familial relation to William. This angered the French duke immensely and, after gaining support from the Vatican, he assembled a vast army consisting of men from Normandy, Flanders, Brittany and France (ie Paris).

Just days after the Battle of Stamford Bridge, William set sail for England and, landing on the south coast, began moving towards London. Harold soon got wind of the invasion and, reassembling his remaining army, marched south at great speed to intercept William. The two armies met on Senlac Hill about ten kilometres (six miles) north-west of the town of Hastings in Sussex.
 
Harold approached the battle three weeks after the Battle of Stamford Bridge with a depleted and tired force (they had marched all the way back from Yorkshire), while in contrast the Norman- French forces were fresh and greater in number. As can be seen in the detailed battlemap and run-through of the key events overleaf, it was an incredibly bloody affair and one in which we all know William came out on top, subsequently taking the English throne.

Battle of Hastings Scheme
Many reasons have been put forward by military historians for Harold’s defeat, but most agree on three pivotal points. Firstly, he was too keen to engage the threat of William, marching an exhausted army all the way from northern England at great speed to fight. Secondly, despite stopping by in London en route to face William, he failed to appreciate the city’s defensive capabilities and didn’t hole up there – a move that would have swung the odds much more in his favour. And finally, after taking up an advantageous position on the battlefield (atop Senlac Hill) he failed to maintain discipline within his troops, which meant the lines were broken easily by a little deception.
 
Unlike the results of many other succession wars, this outcome radically altered the way England developed. Once William had succeeded Harold, the Norman Conquest of the country began proper – a process that would see the vast majority of the ruling classes displaced as well as a complete overhaul of the country’s administrative structure – the Domesday Book is great evidence of this.
 
The Anglo-Saxon language was also phased out in favour of French, trading and diplomatic ties with mainland Europe strengthened, new stone castles, cathedrals and civic buildings were built all over the country and England became a new financial powerhouse in Europe. Indeed, modern England – and Britain in general – was hugely shaped by the Norman takeover.
