What year did compulsory military start?

Compulsory military service, also known as conscription, has been implemented in various forms throughout history. One of the earliest and most notable instances occurred during the French Revolution in 1793 when the levée en masse was enacted, requiring all able-bodied men to serve. Many countries adopted similar practices in the 19th and 20th centuries, particularly during times of war. However, the specific year compulsory military service began varies by country and context.
