Why did Maximilien Robespierre support mass conscription during the French Revolution?

Maximilien Robespierre supported mass conscription, known as the levée en masse, as a vital necessity to ensure the survival of the French Revolution. During his time on the Committee of Public Safety, France faced a desperate situation, threatened by both internal civil war and an external anti-French coalition.12

Robespierre believed that to achieve victory, the nation had to mobilize all its resources under "one single will" (une volonté une). He viewed mass conscription, alongside economic dictatorship and the intensification of the Reign of Terror, as essential measures to defend the Republic against its foreign and domestic enemies. By placing the economy on a wartime basis and requiring all able-bodied unmarried men between 18 and 25 to enlist, the government sought to create a massive popular mobilization that would reinforce the militant spirit of the revolution.123
