Maria Theresa of Austria (r. 1740-1780) was the only female Habsburg ruler, who centralized administration, reformed the army and schools, and defended her throne in the War of Austrian Succession; on the AP Euro exam she's the pragmatic reformer contrasted with fully enlightened absolutists like her son Joseph II.
Maria Theresa inherited the Habsburg dominions in 1740 as the only female ruler in the dynasty's history, and she had to fight for that inheritance immediately. Frederick II of Prussia seized the rich province of Silesia, triggering the War of Austrian Succession. Losing Silesia convinced her that the Habsburg state was outdated, so she spent the next four decades fixing it. She centralized tax collection and administration, rebuilt the military, and pushed education reform, including compulsory primary schooling, the reform she's most often associated with on exams.
Here's the nuance the AP Euro CED actually cares about. Maria Theresa was a reformer, but not a true enlightened absolutist. The CED lists Frederick II of Prussia and Joseph II of Austria (her son) as the enlightened monarchs; Maria Theresa appears alongside them as a Habsburg ruler whose reforms were driven by practical state-building, not Enlightenment philosophy. She was a devout Catholic who resisted religious toleration. Think of her as the ruler who modernized the machinery of the state so that Joseph II could later attach Enlightenment ideas to it.
Maria Theresa lives in Topic 4.6, Enlightened and Other Approaches to Power, in Unit 4. She supports learning objective AP Euro 4.6.A, which asks you to explain how different forms of political power were influenced by Enlightenment thought from 1648 to 1815. She's your best evidence for the "other approaches" half of that topic title. While eastern and central European states experimented with enlightened absolutism (KC-2.1.I.C), Maria Theresa shows that reform could happen without Enlightenment motives. She also connects to 4.6.B and KC-2.1.III.A, since her reign sits inside the bigger story of the Habsburgs shifting their empire eastward after the Peace of Westphalia limited their power in the Holy Roman Empire. For comparison and continuity questions, she's the perfect baseline against which Joseph II's more radical Enlightenment program gets measured.

Enlightened Absolutism (Unit 4)
Maria Theresa is the test case for whether reform equals enlightenment. She centralized and modernized like Frederick II or Catherine the Great, but her motives were dynastic survival and Catholic piety, not philosophe ideas. The CED deliberately lists her separately from the enlightened monarchs.
War of Austrian Succession (Unit 3)
Frederick II's grab of Silesia in 1740 challenged Maria Theresa's right to inherit and kicked off this war. It matters because the loss of Silesia is the cause and her reform program is the effect. Defeat taught her that the Habsburg state needed an overhaul to compete with Prussia.
Habsburg Empire (Units 2-4)
After the Peace of Westphalia weakened Habsburg control over the Holy Roman Empire (KC-2.1.III.A), the dynasty rebuilt its power eastward in Austria, Hungary, and Bohemia. Maria Theresa's centralizing reforms are how that eastward-facing empire got organized into a functioning modern state.
Catherine the Great (Unit 4)
Catherine corresponded with philosophes and branded herself as enlightened; Maria Theresa wanted nothing to do with them. Putting the two side by side gives you a ready-made comparison of how 18th-century rulers used (or ignored) Enlightenment language while pursuing similar state-building goals.
Maria Theresa shows up most often in multiple-choice questions about 18th-century reform and enlightened absolutism, often paired with a passage or chart about Habsburg administration. Practice questions ask which reform she's most known for, so know her education reforms (compulsory primary schooling) and her administrative and military centralization. The classic trap is treating her as an enlightened absolutist; the exam rewards you for knowing her reforms were pragmatic, not philosophical, and that her son Joseph II is the Habsburg ruler who actually fits the enlightened label. No released FRQ has used her name verbatim, but she's strong evidence for LEQs and comparison essays on how Enlightenment thought did or didn't shape political power from 1648 to 1815.
They're mother and son, both Habsburg rulers, and they even co-ruled from 1765 to 1780, so mixing them up is easy. The difference is motive and degree. Maria Theresa reformed to strengthen the state and stayed a committed Catholic who opposed religious toleration. Joseph II reformed because he genuinely believed Enlightenment ideas, granting toleration to Protestants and civil rights to Jews (connecting to KC-2.3.IV.C). If an exam question is about toleration or radical Enlightenment-driven reform in Austria, the answer is Joseph II, not Maria Theresa.
Maria Theresa ruled the Habsburg dominions from 1740 to 1780 and was the only woman ever to do so.
Frederick II's seizure of Silesia in the War of Austrian Succession pushed her to centralize administration, rebuild the military, and reform education.
She is most known for education reform, including compulsory primary schooling in the Habsburg lands.
The CED does not classify her as an enlightened monarch; her reforms were pragmatic state-building, while her son Joseph II is the Habsburg ruler who embodied enlightened absolutism.
She remained a devout Catholic and resisted religious toleration, which is exactly what separates her from Joseph II on exam questions.
Her reign fits the bigger pattern of the Habsburgs shifting power eastward after the Peace of Westphalia limited their authority in the Holy Roman Empire.
She ruled the Habsburg dominions from 1740 to 1780, defended her inheritance in the War of Austrian Succession, and modernized her empire by centralizing taxes and administration, rebuilding the army, and creating compulsory primary education.
No, not in the way AP Euro defines it. She reformed for practical reasons (competing with Prussia), stayed a devout Catholic, and opposed religious toleration. The AP Euro CED lists Frederick II of Prussia and her son Joseph II as the enlightened monarchs, not her.
Maria Theresa reformed to strengthen the Habsburg state while keeping Catholic dominance; Joseph II, her son and co-ruler from 1765, reformed because of Enlightenment ideals, extending toleration to Protestants and civil equality to Jews. Same dynasty, very different motives.
When Maria Theresa inherited the Habsburg throne in 1740, Frederick II of Prussia challenged her claim and seized the wealthy province of Silesia. The war confirmed her rule but cost her Silesia, which drove her entire reform program afterward.
Yes. She's named in the CED under Topic 4.6 (Enlightened and Other Approaches to Power) as a Habsburg ruler, and she shows up in multiple-choice questions about 18th-century reform and as comparison evidence in essays about enlightened absolutism.
