What is an alliance?

An alliance is the act or state of being in a mutually beneficial relationship to work toward a common goal, as in The United States’ longest alliance is with France. 

Often, alliance refers to a formal agreement between nations that promise to assist each other in war, as in Germany, Italy, and Japan agreed on an alliance during World War II. 

Alliance can also be used more generally to refer to the people or groups that come together in a common cause, as in The invading orcs were defeated by an alliance of men, elves, and dwarves. 

Alliance is similar to words such as confederation, union, and league, which also refer to beneficial partnerships. Alliance is used more generally than these words, however.

Example: The kids at my school formed an alliance to stop the bully from harassing us. 

Where does alliance come from?

The first records of the word alliance come from around 1250. It ultimately comes through the Old French alier, meaning “to ally.” An alliance is created when multiple groups or people decide to ally (join in partnership) with each other.

You have probably seen the word alliance used in history books, especially when learning about wars. Throughout history, nations have repeatedly formed alliances to avoid war or to help defend each other from a larger, more powerful threat. Both World War I and World War II involved alliances between a significant number of nations. In fact, World War I only escalated as badly as it did thanks to a complex web of alliances that forced many different countries into the conflict.
