If you were to approach your secondary school or history teacher or any friends who happen to be history buffs, they would likely tell you how the Battle of Hastings, which took place back in 1066, is one event that significantly altered the future of England.
The reason it is said to have shaped England we know today so much is it introduced Norman governance and influenced the nation's culture and societal framework for generations to come. This significant battle was part of William of Normandy's bid for the English throne, where he was backed by papal support and a diverse European army.

Despite Harold Godwinson's impressive victory over Norwegian invaders at Stamford Bridge, his forces were exhausted and outmanoeuvred by William's tactical prowess at Hastings. William was triumphant, and this led to the Norman Conquest which would change more than we may have considered about the trajectory of the nation’s history, including linguistic, cultural, and social landscape.

Battle of Naseby (1645)
You can’t have a conversation about the best British battles throughout history without the Battle of Naseby. The Battle marked a turning point in history by reshaping the dynamic between the monarchy and parliament. This clash occurred during the English Civil War, and the Parliamentarian New Model Army under Fairfax and Cromwell achieved a massive victory over King Charles’ Royalist troops. A common denominator from what happened in Agincourt was the strategic brilliance on show from Cromwell, who executed a cavalry charge that clinched their victory on the day.

Battle of Culloden (1746)
The next example of British warfare that we’re going to tuck into today is the Battle of Culloden, which put an end to the Jacobite Rising and marked a new chapter for Scotland and Britain as a whole. What’s interesting about this battle is that the clashing forces of Bonnie Prince Charlie's Jacobite forces and the Duke of Cumberland government army also represented a collision of beliefs and aspirations for Britain's future.
The Jacobites had picked up a fair few victories over the course of the conflict, but Culloden saw their demise. Despite their bravery in the Highland charge, they could not withstand the firepower of Cumberland's soldiers.
