Federation vs. Union: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on November 7, 2023
A federation is a political entity characterized by a union of partially self-governing regions under a central government, while a union is the act of joining two or more things into one.

Key Differences

A federation refers to a form of government where several states form a unity but remain independent in internal affairs. A union is a general concept of coming together, which can be applied to a variety of contexts, including political, social, or labor-related situations. Federations are political entities with a constitutional structure dividing powers between the central government and its constituent parts. Unions may not have such a structured division of powers and can refer to the act of uniting or the state of being united across diverse realms.
In a federation, constituent states or regions have their own governments, laws, and policies to some extent, such as in the United States or Russia. In contrast, a union can be a group of workers who come together to collectively bargain for rights and wages, or countries joining together for economic or political purposes without the federal structure, like the European Union. Federations often have a complex legal framework to manage the balance of power, whereas unions may be governed by agreements, contracts, or mutual understandings.
Federations usually have a written constitution that details the powers of the federal government and the regional governments. The concept of a union is broader and can include alliances formed for mutual benefit without a formal constitutional basis, such as trade unions or marital unions. The federation’s focus is on governance and political structure, ensuring unity while maintaining the individuality of its parts. Unions focus on the act of joining and the benefits derived from strength in numbers, regardless of the context.
