The other form of patrimonialism is still top down but it approaches the Ideal Type of Western European Feudalism, with a basis for legitimate authority outside of the central ruler's authority. In 12th century France or England, for example, it could have consisted of the knightly aristocracy. This feudal form of patrimonialism eventually evolved into Constitutional Monarchy. The U.S. Senate is a vestige of the House of Lords in England. The Lords were literally the peers of the realm. Weber's overarching argument was that with modernity, traditional bureaucratic patrimonial forms of government eventually gave way to modern capitalist bureaucratic rationalism as the main principle of both government and governance.
