Conscription

Conscription is the compulsory enlistment of people in some sort of national service, most often military service. Conscription dates back to antiquity and continues in some countries to the present day under various names. The modern system of near-universal national conscription for young men dates to the French Revolution in the 1790s, where it became the basis of a very large and powerful military. Most European nations later copied the system in peacetime, so that men at a certain age would serve 1–3 years on active duty and then transfer to the reserve force.

In China, the State of Qin instituted universal military service following the registration of every household. This allowed huge armies to be levied, and was instrumental in the creation of the Qin Empire that conquered the whole of China in 221BC.

Conscription is controversial because of conscientious objection to service or because of political objection to service for a disliked government or an unpopular war, and because it violates individual rights. Those conscripted may evade service, sometimes by leaving the country. Some selection systems accommodate these attitudes by providing alternative service outside combat-operations roles or even outside the military, such as Zivildienst in Austria and Switzerland.

As of the early 21st century, many states no longer conscript soldiers, relying instead upon professional militaries with volunteers enlisted to meet the demand for troops. The ability to rely on such an arrangement, however, presupposes some degree of predictability with regard to both war-fighting requirements and the scope of hostilities. Many states that have abolished conscription therefore still reserve the power to resume it during wartime or times of crisis. In the United States, conscription, also called "the draft", ended in 1973, but males between 18 and 25 are required to register with the Selective Service System to enable a reintroduction of conscription if necessary.
