How did William of Normandy do the tax?

William of Normandy, after his conquest of England in 1066, implemented a structured taxation system to consolidate his rule and fund his government. He commissioned the Domesday Book in 1086, a comprehensive survey that recorded landholdings, resources, and populations, allowing for efficient tax assessment. This system not only streamlined tax collection but also established a clear hierarchy of land ownership, which reinforced William's authority over his new realm. Through these measures, he ensured a steady revenue stream to support his administration and military.
