How did napoleon reduce the power of the pope?

Napoleon reduced the power of the pope primarily through the Concordat of 1801, which redefined the relationship between the French state and the Catholic Church. While it restored some church functions and allowed Catholics to practice their religion, it also placed the church under state control, limiting the pope's influence over French affairs. Additionally, Napoleon's establishment of a secular legal system and promotion of state-sponsored education further diminished the Church's authority in France. Ultimately, Napoleon's actions reflected his desire to consolidate power and assert state dominance over religious institutions.
