☞ This term is applied to governments which are considered as free or popular, but rarely, or improperly, to an absolute government. The word signifies, strictly, the common well-being or happiness; and hence, a form of government in which the general welfare is regarded rather than the welfare of any class. [ 1913 Webster ]

2. The whole body of people in a state; the public. [ 1913 Webster ]

3. (Eng. Hist.) Specifically, the form of government established on the death of Charles I., in 1649, which existed under Oliver Cromwell and his son Richard, ending with the abdication of the latter in 1659.
