William of Ockham’s Political Philosophy
Context and Focus
William of Ockham, a Franciscan friar in the 14th century, challenged medieval scholasticism by advocating for the separation of church and state.

Political Organization and Crises in the Kingdom of Castile
5.1. Political Organization: Institutions of the Kingdom of Castile
Royalty: At the head of the kingdom, the supreme authority is “by the grace of God.” Its power comes from the people, to whom he has delivered God. The only intermediary between God and the king is the people, represented by privileged classes. Succession to the throne in León follows the hereditary principle: the line of male succession (oldest son, 2nd child, and so on). A lack of a male could lead to women exercising sovereignty
The Enlightenment and Key Thinkers: A Philosophical Overview
The Enlightenment
