How did Henry VII increase royal power?

After the War of the Roses which lasted from 1455 until
1485, Henry Tudor (1457-1509) ascended the throne.  However, there were other claimants
who continually challenged him; in response, he increased the monarchy's power at the
expense of the nobles, chiefly by his bypassing of Parliament.  He did so by first
creating the Committee of the Privy Council, similar to our concept of an executive's
cabinet acting as an executive advisory board. Secondly, he established the Court of the
Star Chamber to increase royal involvement in civil and criminal cases. Finally, he
imposed forced loans and grants on the nobility, keeping them under his financial
control.  Additionally, he expanded the English Merchant Marine by the Navigation Acts
(1485) which increased trade, which increased tax revenue.  Much of the wealth amassed
during his reign was sadly dispersed by his son, Henry VIII.
