Frederick II of Prussia (Frederick the Great, r. 1740-1786) was an enlightened absolutist who modernized Prussian law, expanded religious toleration, and built Prussia into a great power through wars like the War of Austrian Succession and the Seven Years' War.
Frederick II of Prussia, better known as Frederick the Great, ruled from 1740 to 1786 and is the CED's headline example of an enlightened absolutist. He kept all the power of an absolute monarch but justified that power with Enlightenment logic. He called himself the "first servant of the state," reformed and rationalized Prussia's legal code, abolished judicial torture, expanded religious toleration, and promoted merit in the bureaucracy. He even corresponded with Voltaire and hosted him at court.
Here's the catch you need for the exam, though. Frederick was also deeply traditional where it counted. He inherited a powerful army and efficient bureaucracy from his father, Frederick William I, and used them aggressively. He seized Silesia from Maria Theresa of Austria in 1740, kicking off the War of Austrian Succession, and fought for survival in the Seven Years' War. He also protected the Junkers (Prussian nobles) and left serfdom largely intact on their estates. Think of him as Enlightenment ideas bolted onto a Prussian war machine. The reforms were real, but they served state power, not popular sovereignty.
Frederick II is named directly in the CED under Topic 4.6 (Enlightened and Other Approaches to Power) as both an enlightened monarch and a Prussian/Habsburg ruler, supporting AP Euro 4.6.A: explaining how Enlightenment thought influenced political power. KC-2.1.I.C says eastern and central European states "experimented with enlightened absolutism," and Frederick is the experiment the exam expects you to know. He also shows up in Topic 3.8 comparisons of political power (AP Euro 3.8.A), where Prussia's centralization contrasts with constitutional states like Britain, and in Topic 5.9 (AP Euro 5.9.A) as evidence for continuity and change in 18th-century states. His rise also illustrates KC-2.1.III.A, where the Peace of Westphalia's weakening of the Holy Roman Empire opened the door for Prussia to become a great power. One ruler, three units. That's why he's worth knowing cold.

Enlightened Absolutism (Unit 4)
Frederick is the textbook case of this concept. If an MCQ or LEQ asks you to define enlightened absolutism with evidence, his legal reforms, religious toleration, and "first servant of the state" line are your go-to proof.
War of Austrian Succession (Unit 5)
Frederick started this war in 1740 by seizing Silesia from Maria Theresa. It's your evidence that his Enlightenment talk never softened his power politics, and it set up the Austro-Prussian rivalry that shaped central Europe for a century.
Seven Years' War (Unit 5)
Austria's attempt to win Silesia back pulled Frederick into a war for Prussia's survival (1756-1763). He held on against Austria, France, and Russia, which cemented Prussia's status as a great power and showed how 18th-century balance-of-power diplomacy actually worked.
Catherine the Great (Unit 4)
Catherine of Russia is Frederick's closest parallel, another eastern European ruler who flirted with philosophes while keeping serfdom and absolute power. Comparing them is a classic way the exam tests whether enlightened absolutism was reform or rebranding.
Frederick II shows up in multiple-choice questions that test the tension at the heart of enlightened absolutism. Practice questions ask how his legal and military reforms reflected Enlightenment ideals, how his rule differed from traditional absolutism, and where he showed continuity with predecessors like Frederick William I (answer: the army and centralized bureaucracy). No released FRQ has used his name verbatim, but he's prime evidence for LEQs on continuity and change in 18th-century states (Topic 5.9) and comparisons of political power (Topic 3.8). The skill the exam wants is nuance. Don't just say he was enlightened. Show both sides: rational legal reform and toleration on one hand, aggressive war and preserved serfdom on the other.
Easy to mix up because both are CED-named Prussian rulers. Frederick William I (the father) was the "Soldier King" who built the army and bureaucracy but had zero interest in Enlightenment ideas. Frederick II (the son) inherited that machine and added the Enlightenment layer, legal reform, toleration, and Voltaire. Father builds the tool, son uses it with philosophical branding.
Frederick II of Prussia (r. 1740-1786) is the CED's named example of enlightened absolutism, combining absolute monarchical power with Enlightenment-inspired reforms.
His enlightened reforms included rationalizing the legal code, abolishing judicial torture, expanding religious toleration, and calling himself the "first servant of the state."
He showed continuity with traditional absolutism by relying on the army and bureaucracy built by his father, protecting noble (Junker) privileges, and leaving serfdom intact.
His seizure of Silesia in 1740 started the War of Austrian Succession, and his survival in the Seven Years' War made Prussia a great power.
Prussia's rise under Frederick traces back to the Peace of Westphalia weakening the Holy Roman Empire, which let Prussia centralize and expand (KC-2.1.III.A).
On the exam, the winning move is showing both sides of Frederick: Enlightenment reformer in domestic policy, ruthless power politician in foreign policy.
He ruled Prussia from 1740 to 1786, modernized its legal system, expanded religious toleration, seized Silesia from Austria, and survived the Seven Years' War, turning Prussia into a European great power.
Both, and that's the exam answer. His legal reforms, toleration, and friendship with Voltaire were genuinely Enlightenment-influenced, but he kept serfdom, protected the Junker nobility, and waged aggressive war. Enlightened absolutism reformed the state to strengthen it, not to share power.
Frederick William I was his father, the "Soldier King" who built Prussia's army and bureaucracy with no Enlightenment agenda. Frederick II inherited that system and added Enlightenment reforms like legal rationalization and religious toleration.
No. Despite his Enlightenment reputation, Frederick left serfdom largely intact on noble estates because he depended on the Junkers to staff his army and administration. This limit on his reforms is a favorite MCQ angle.
He saw Maria Theresa's new and contested accession in Austria as a chance to grab the wealthy province and boost Prussian power, which launched the War of Austrian Succession. It's the clearest proof that Enlightenment ideals didn't change his foreign policy.
