What this topic is asking
Topic 4.6 asks you to explain enlightened absolutism (also called enlightened despotism): how 18th-century rulers used Enlightenment ideas to reform their states while keeping centralized royal power. The College Board wants the leading examples, Frederick the Great, Catherine the Great, and Joseph II, their reforms, and, crucially, the limits of that reform.
What enlightened absolutism was
The key tension to grasp is that these rulers were both enlightened (drawing on the philosophes) and absolutist (keeping sovereignty in the crown). They used the Enlightenment instrumentally.
The three classic rulers
| Ruler | State | Signature reforms |
|---|---|---|
| Frederick the Great | Prussia | Legal reform, toleration, education, support for arts and sciences |
| Catherine the Great | Russia | Education, legal commission, patronage of the Enlightenment |
| Joseph II | Austria | Religious toleration, reduced Church power, serfdom reform |
The limits of reform
Why it mattered
Enlightened absolutism shows the Enlightenment's ideas entering government, but on the rulers' terms. It modernized the administration, law, and toleration of several major states and is a key case for the continuity and change skill: real reform, but bounded by the continuity of absolute power and social hierarchy. It also sets up a contrast with Unit 5: where enlightened rulers reformed from above without surrendering power, the French Revolution would attempt change from below by overthrowing the old order entirely.

- Cue. Frederick the Great of Prussia, Catherine the Great of Russia, and Joseph II of Austria.
Q2. Explain the main limit on enlightened reform. [Short explanation]

A. Describe: Joseph II's grant of religious toleration, or Frederick the Great's legal and administrative reforms, or Catherine the Great's promotion of education and a new legal commission.
B. How Enlightenment ideas shaped them: rulers drew on Enlightenment principles of reason, toleration, and efficient law to modernize their states.
C. Limit: reforms were used to strengthen royal power, not to give it up, and rulers rarely touched serfdom or shared real authority, so change was limited.
Markers want a reform, an Enlightenment influence, and a clear limit.

A Long Essay Question (LEQ), scored on the 6-point continuity-and-change rubric.
Thesis (1): "Enlightened absolutists adopted Enlightenment ideas selectively, reforming law, toleration, and administration, but they used these reforms to strengthen royal power rather than to limit it, so the change was real but bounded by absolutism."
Contextualization (1): the spread of Enlightenment ideas and the absolutist tradition of Unit 3.
Evidence (2): Frederick's legal and economic reforms; Catherine's education and legal projects; Joseph II's toleration and serfdom reforms.
Analysis (2): weigh genuine reform against the continuity of centralized power, arguing rulers used the Enlightenment instrumentally, then add complexity by comparing rulers (Joseph went furthest).
