How did 111 gain territory paving the way for him to established the tradition of absolute monarchy?

King Henry I of England, often referred to as Henry I or Henry Beauclerc, expanded his territory through strategic marriages, military conquests, and the consolidation of power. He successfully claimed the English throne after the death of his brother, William II, and utilized his resources to secure territories in Normandy and parts of Wales. By establishing a strong central government, implementing legal reforms, and diminishing the power of the nobility, he laid the groundwork for a tradition of absolute monarchy that emphasized royal authority over feudal lords. His reign marked a shift towards a more centralized form of governance, setting a precedent for future monarchs.
