William the Conqueror's Introduction to England
William the Conqueror introduced Norman rule to England, which significantly altered the course of English history. After his victory at the Battle of Hastings in 1066, William instituted a new order in the country. He commissioned the construction of numerous churches, such as Durham Cathedral, and ecclesiastical buildings showcasing Norman architecture. Additionally, he introduced the feudal system, a hierarchical structure that shaped the kingdom's social and political organization.
Military innovations such as the motte-and-bailey castle were also introduced, providing strong defensive structures for the Normans. William commissioned the creation of the Bayeux Tapestry, which provides a valuable visual record of the events surrounding the Norman Conquest and their military tactics, including the strategic use of cavalry. In essence, the conquest led to a transformation of English society, governance, architecture, and military strategy.
