## Step 1<br />The problem is about the historical policy of Han Wudi, a Chinese emperor of the Han Dynasty. The policy in question is the division of noble estates among sons. This policy was not primarily about ensuring equity among brothers, achieving efficient estate management, or providing a better revenue base. <br /><br />## Step 2<br />The division of noble estates among sons was a strategic move to weaken the power of the vassals. By dividing the estates, the emperor reduced the concentration of wealth and power in the hands of a few nobles. This made it easier for the central government to control the nobility and prevent them from becoming too powerful.<br /><br />## Step 3<br />This policy was part of a broader strategy to consolidate the emperor's power and ensure the stability of the Han Dynasty. By weakening the vassals, the emperor could maintain control over the vast territories of the empire and ensure the loyalty of the nobility.
