A more thorough explanation:

Definition: Levée en masse is a French term that means "mass levy" or "mass conscription." It refers to a policy of mandatory military service for all able-bodied men during times of war or national emergency.

Example: During the French Revolution, the Committee of Public Safety implemented a levée en masse, which required all French men between the ages of 18 and 25 to serve in the military. This policy helped to create a large and powerful army that was able to defend France against its enemies.

Explanation: The example illustrates how levée en masse was used as a way to mobilize a large number of soldiers quickly and efficiently. By requiring all able-bodied men to serve in the military, governments could create a powerful fighting force that was capable of defending the nation against external threats. This policy was often used during times of war or national emergency, when it was necessary to quickly build up the military to protect the country.
