the.com/federation

Many states pretending to share a kitchen while secretly fighting over the thermostat.

means A union of states or groups that hand over certain shared powers (like defense or currency) to a central authority while keeping control over their own internal affairs.

from From the Latin foedus, meaning 'covenant' or 'treaty' — the same root that gives us 'confederate' and 'fidelity.' At its heart sits the idea of a binding pact, a promise sworn between parties, which is why federations are essentially formalized agreements to play nicely together. The word entered English through French (fédération) and gained real political weight in the 18th century, especially around the founding of the United States.
