Allied

Allied is an adjective describing something that is joined or aligned in an alliance or partnership. The term is frequently used in international relations to denote cooperation between states, organizations, or other actors that share common goals or commitments. In historical contexts, Allied powers or Allies refer to the coalition of nations that opposed the Axis during World War II; the principal members included the United States, the United Kingdom, the Soviet Union, China, and France, with other governments joining at various times. The Allies coordinated military operations, diplomacy, and aid across multiple theaters, ultimately contributing to the defeat of the Axis powers in 1945 and to the postwar establishment of institutions such as the United Nations.

In contemporary use, Allied appears in names of corporations, agencies, and initiatives that emphasize partnership. It also serves as a film title: Allied is a 2016 American historical spy thriller directed by Robert Zemeckis, starring Brad Pitt and Marion Cotillard, about a married couple recruited to work as spies during World War II.

The term remains a common descriptor in political science and military discourse, indicating a formal or informal partnership between states or groups working toward shared objectives, whether in security, humanitarian, or economic contexts.
