Levellers. A fanatical party in Germany, headed by Muncer and Storck in the 16th century, who taught that all distinctions of rank were usurpations on the rights of mankind. At the head of 40,000 men Muncer commanded the sovereign princes of Germany and the magistrates of cities to resign their authority; and on his march his followers ravaged the country. The landgrave of Hesse at last defeated him; 7000 of the enthusiasts fell in battle, and the rest fled; their leader was taken and beheaded at Mulhausen in 1525. The English “Levellers,” powerful in Parliament in 1647, were put down by Cromwell in 1649, and their leader, Lilburn, imprisoned.

Levy (Fr. levée). Is the compulsory raising of a body of troops from any specified class in the community for purposes of general defense or offense. When a country is in danger of instant invasion, a [levée en masse] is sometimes made,—i.e., every man capable of bearing arms is required to contribute in person towards the common defense. On less urgent occasions, the levy may be restricted to a class, as to men between eighteen and forty years of age. At other times, a levy of so many thousand men of a certain age is decreed, and the districts concerned draw them by lot from among their eligible male population. In armies sustained by volunteering, the levy, which is a remnant of barbarous times, is unnecessary; but the system was frequently resorted to in France before the enactment of the conscription laws. In 1862-64 there were great levies in the United States of America; and in any country where great danger is apparent, and volunteers are not sufficiently numerous, recourse must at all times be had to a levy of the people. This term is also applied to the assessment of taxes, tolls, or contributions.
