Knights of Labour.
Members of a trades union organised in 1834, in the United States of America, to regulate the amount of wages to be demanded by workmen, the degree of skill to be exacted from them, and the length of a days work. This league enjoins when a strike is to be made, and when workmen of the union may resume work.
