From the Peace of Westphalia to the Congress of Vienna, Europeans debated who possessed legitimate authority, creating rival systems of sovereignty that reshaped diplomacy, taxation, law, and the political obligations of rulers and ruled.

Sovereignty After 1648

After 1648, European politics increasingly centered on territorial states rather than universal religious authority.

Rulers claimed the right to govern within defined borders, negotiate with other powers, and command obedience at home. Yet there was no single European model. Different states answered the question of supreme authority in different ways, producing competing forms of sovereignty.

In practice, sovereignty depended on more than theory. It required armies, bureaucracies, courts, and reliable taxation. Between 1648 and 1815, those tools expanded, but the source of authority remained contested.

Absolutist Sovereignty

Dynastic monarchy

In many continental states, especially France under Louis XIV, sovereignty was closely identified with the monarch. Kings justified power through divine right, treated the state as a dynastic inheritance, and tried to weaken the political independence of nobles, representative estates, and churches. Royal officials extended authority into the provinces, while permanent armies and regular taxation made rulers less dependent on older feudal obligations.

This model changed relations between governments and individuals by emphasizing obedience over participation. Most people were subjects, not citizens. Access to rights depended heavily on rank, privilege, and local custom. Even so, absolutism was never total: elites, provincial institutions, and financial weakness still limited what monarchs could actually do.

Constitutional and Parliamentary Sovereignty

Limited monarchy

A different model developed most clearly in England and later Great Britain after the Glorious Revolution. Here, legitimate authority rested less on the personal will of the ruler and more on law and representative institutions. The monarch remained important, but taxation and legislation increasingly depended on Parliament. Sovereignty was therefore tied to a political system, not simply to a dynasty.

This arrangement altered relations between rulers and ruled. Political participation remained narrow, but elites expected protection for property, legal process, and traditional liberties. Government could be strong while still facing institutional limits. This model showed that European states did not all centralize through absolutism; some did so through constitutional structures.

Reforming Monarchy in the Eighteenth Century

Enlightened absolutism

Some rulers tried to modernize sovereignty without giving up monarchical control. Frederick II, Joseph II, and Catherine the Great presented themselves as rational reformers working for the public good. Their authority still remained concentrated at the top, but they justified it through reason, efficiency, and administrative improvement rather than tradition alone.

These monarchs sought more uniform law, closer control of the church, and better administration. The individual’s relationship to the state became more direct because central governments increasingly counted, taxed, educated, and regulated their populations. Yet these reforms rarely created meaningful political participation. Sovereignty could become more efficient without becoming more representative.

Popular Sovereignty

From subjects to citizens

By the late eighteenth century, the most radical shift was the claim that sovereignty belonged to the nation or the people.

This challenged the idea that states were the property of ruling families. Legitimate government was increasingly defined as government based on a constitution, representation, and the rights of citizens rather than inherited authority.

This model transformed political expectations. Individuals could now be imagined as members of a nation with public responsibilities and claims to participation. At the same time, popular sovereignty could demand intense loyalty, military service, and sacrifice. Once authority was said to come from the nation, politics became more ideological and more emotionally charged, and older regimes saw this as a major threat to European stability.

Effects on European Politics

Different models of sovereignty also changed relations among states. In the seventeenth century, diplomacy was still strongly dynastic, with rulers bargaining over territory, marriage, and succession. Over time, however, states became more bureaucratic, more centralized, and more clearly defined by territorial jurisdiction. Governments increasingly acted as permanent institutions rather than as the household power of a ruler alone.

Across the whole period, the major development was not a simple march toward democracy. Instead, Europe moved through competing models: absolutist, constitutional, reforming, and popular. From 1648 to 1815, sovereignty became more centralized, more contested, and more important in shaping both interstate relations and the everyday obligations of individuals.
