What does confederation mean?
A confederation is a union formed when independent states, provinces, or organizations agree to cooperate for shared purposes — typically defense, trade, or diplomacy — while keeping control over their own internal affairs. The term describes both the resulting alliance and the act of forming it. Unlike a federation, where a central government holds substantial power over all members, a confederation leaves its members largely sovereign, delegating only limited authority to a common body; this makes it one of the looser forms of political union. The word is most familiar from history and politics: the Swiss Confederation, the Articles of Confederation that preceded the United States Constitution, and Canadian Confederation of 1867, which created the Dominion of Canada. Because it signals voluntary cooperation among equals, confederation also appears in descriptions of leagues and alliances beyond national politics. Its connotations are formal and institutional, making it a precise word for discussions of governance and union-building.
A union of sovereign states, provinces, or organizations joined for common purposes while retaining control over their own internal affairs.
"The German Confederation coordinated matters of defense among its member states without overriding their sovereignty."
Strictly distinguished from 'federation,' where the central government exercises real authority over member units.
The act or process of uniting separate entities into such an alliance, or the organization resulting from it.
"Canadian Confederation in 1867 brought together several British North American colonies under one government."
Often capitalized when referring to a specific named event or entity, as in Canadian Confederation or the Swiss Confederation.
Regular plural; used when referring to multiple distinct unions or instances of uniting.
"Throughout history, various confederations have arisen to balance local autonomy with collective strength."
Canada and Switzerland are confederations in name — but the Articles of Confederation failed so badly at holding America together that they were replaced within a decade by the U.S. Constitution.

Etymology of confederation
Confederation comes from Latin foederare, 'to bind by covenant,' through the Late Latin foederatio, via Italian federazione and French confédération before entering English in the early modern period. The prefix con- ('together') was added to foedus ('covenant, league') to signal a binding between parties rather than a single unified state. English adopted both confederate and confederacy earlier, with confederation appearing by the mid-16th century. Its cognates include federal and fidelity, all tracing back to the same Latin root for trust-binding agreements.

How confederation is actually used
Confederation carries a formal, institutional register — it appears chiefly in political science, history, law, and journalism about international bodies. In Canadian usage it has a specific patriotic meaning tied to the founding of the country in 1867. The word implies voluntary cooperation among equals rather than centralized rule, which distinguishes it from federation in strict usage; in casual speech the two terms are sometimes used interchangeably, though writers on constitutional matters keep them apart.
Easily confused with confederation
In a federation, member states give up significant authority to a strong central government, whereas in a confederation the members remain largely sovereign and delegate only limited powers to the central body.
A confederacy is essentially the same idea — an alliance of self-governing members — but 'confederacy' often carries historical associations (most famously the Confederate States of America), while 'confederation' is the more neutral political-science term.
