In AP Euro, a Great Power is a state with enough military strength, economic resources, and diplomatic weight to shape international affairs, like Britain, France, Austria, Prussia, and Russia in the 18th century, whose rivalries and alliances drove the balance of power system.
A Great Power is a state that other states have to take seriously. It has the army, the money, and the diplomatic reach to start wars, end them, redraw borders, and decide the fate of weaker neighbors. By the 18th century, Europe had settled into a club of five: Britain, France, Austria, Prussia, and Russia. These five fought each other, allied with each other, and carved up smaller states (Poland being the most famous victim) based on cold calculations of power rather than religion or ideology.
The term matters in Topic 5.9 because the Great Power system is one of the big continuities of the period 1648-1815. Models of sovereignty changed (KC-2.1), the French Revolution blew up the old social order (KC-2.1.IV), and Napoleon overran the continent (KC-2.1.V). But through all of it, the basic logic stayed the same. Strong states pursued their interests, and when one of them (France under Napoleon) got too strong, the others ganged up to restore equilibrium. Commercial rivalries also fed into this, since trade and colonies were power (KC-2.2.III), which is exactly why Britain and France kept fighting each other around the globe.
Great Power sits in Topic 5.9 (Continuity and Change in the 18th-Century States) in Unit 5 and supports learning objective 5.9.A, which asks you to explain how developments and challenges to the political order produced change from 1648 to 1815. Here's the move the exam wants you to make. The French Revolution and Napoleon look like total ruptures, but the Great Power framework is your continuity argument. The same five states that competed before 1789 were the ones that defeated Napoleon and then sat down at the Congress of Vienna to put the system back together. If a continuity-and-change LEQ shows up for this period, 'the Great Power balance of power persisted' is one of the most reliable theses you can build.

Balance of Power (Unit 5)
These two ideas are a matched set. Great Powers are the players, and balance of power is the game they play. The system only works because several roughly equal Great Powers exist to check each other, which is why coalitions kept forming against Louis XIV and later Napoleon whenever France threatened to dominate.
Catherine the Great (Units 4-5)
Catherine shows what Great Power behavior looks like in practice. She expanded Russia at the Ottoman Empire's expense and joined Prussia and Austria in the partitions of Poland (1772, 1793, 1795), erasing a sovereign state purely so the three eastern Great Powers could grow without upsetting their balance.
Diplomacy (Unit 5)
Great Power politics professionalized diplomacy. States negotiated alliances, marriages, and territorial swaps as instruments of national interest, and commercial rivalries (KC-2.2.III) increasingly drove who allied with whom. Diplomacy became how Great Powers competed without constantly fighting.
Imperialism (Unit 7)
The Great Power concept doesn't die in 1815. It evolves. By the late 19th century, overseas empire became the new measure of Great Power status, which helps explain the Scramble for Africa and why newly unified Germany wanted colonies. Same competitive logic, bigger map.
Multiple-choice questions tend to test whether you can recognize Great Power logic at work in a specific event. Practice questions in this style ask what the partitions of Poland illustrate about 18th-century international relations (answer: Great Powers expanding at a weaker state's expense to preserve their own balance) or what problem the Concert of Europe addressed after Napoleon (answer: containing revolutionary challenges and preventing any single power from dominating again). No released FRQ has used 'Great Power' verbatim, but the concept is gold for continuity-and-change LEQs on the period 1648-1815. Use it to argue that despite revolutionary upheaval, interstate competition among the same handful of strong states remained the organizing principle of European politics.
Great Power describes a single state's status. Balance of power describes the relationship among those states. Britain was a Great Power; the system that kept Britain, France, Austria, Prussia, and Russia from being conquered by any one of them was the balance of power. If a question asks about a country's strength, think Great Power. If it asks about alliances forming to check an overly strong state, think balance of power.
A Great Power is a state with the military, economic, and diplomatic strength to shape European affairs, and by the 18th century the club had five members: Britain, France, Austria, Prussia, and Russia.
The partitions of Poland (1772, 1793, 1795) are the classic example of Great Power behavior, where Russia, Prussia, and Austria absorbed a weaker state to expand without disturbing their mutual balance.
The Great Power system is a continuity argument for 1648-1815: the French Revolution and Napoleon challenged the political order, but the same five powers defeated France and restored equilibrium at the Congress of Vienna.
Commercial rivalry was part of Great Power competition, which is why Britain and France fought repeatedly over trade and colonies during the 18th century (KC-2.2.III).
Great Power and balance of power are not the same thing; one names a strong state, the other names the system those states used to check each other.
A Great Power is a state strong enough militarily, economically, and diplomatically to shape international politics. In the 18th century, the five Great Powers were Britain, France, Austria, Prussia, and Russia, and their rivalries and alliances are the backbone of Unit 5.
No. The Revolution and Napoleon challenged it hard, but the system survived. The other Great Powers formed coalitions, defeated Napoleon, and restored the balance at the Congress of Vienna in 1815, which is why this works as a continuity argument on LEQs.
A Great Power is an individual strong state; balance of power is the system among them. The five Great Powers maintained the balance by allying against any state that got too dominant, like the coalitions against Napoleon.
In 1772, 1793, and 1795, Russia, Prussia, and Austria divided Poland among themselves until it vanished from the map. It shows Great Powers expanding at a weaker state's expense while keeping their own balance intact, a favorite MCQ scenario.
Britain, France, Austria, Prussia, and Russia. Prussia and Russia were the newcomers, rising in the 18th century, while declining states like Poland, the Ottoman Empire, and Spain became targets rather than players.
