This document analyzes the genesis of liberalism, understood as a reaction against the absolutist state and its conditions. Absolutism, dominant in Europe by the end of the 16th century, evolved from Italian Renaissance states due to advancements in transport, trade, and military technology, leading to the weakening of estates and the centralization of power. It was ideologically reinforced by Machiavelli, Bodin, and Hobbes, and by the Reformation, which subordinated the church to secular power. Church property and early capitalism formed the material base. France under Louis XIV and Spain under Philip II are presented as examples of absolutist states with extensive bureaucratic apparatus and standing armies, often financed by unjust taxation of the populace. Mercantilist policies, prioritizing state interests over individual ones, and the social division between a privileged nobility and an oppressed bourgeoisie are key features. Liberalism emerged as a protest against this tyranny and oppression, emphasizing resistance to violence and military armament. John Locke is presented as a key thinker whose ideas influenced the English Revolution and strengthened the concept of individual freedoms and rights. The document further describes England's political development in the 17th century as a contrast to continental absolutism, where Parliament and laws like Magna Carta and the Bill of Rights limited royal power and secured personal and economic freedom, thus laying the foundations for modern liberalism.
