Ranters were an English radical group of religious libertines c. 1649-54 who engaged in a wide written campaign of spirited religious and political pamphleteering (though their spelling and grammar were apparently, for want of editors, horrid) while also carrying on, at the street level (allegedly), with frenzied drunken orgies and immoral wantoness. One of the best works on the subject is the amazing overview, The pursuit of the millennium : revolutionary messianism in medieval and Reformation Europe and its bearing on modern totalitarian movements by Norman Cohn (NY : Harper, 1961)

The most infamous Ranter was Laurence Claxton, a tailor by trade, who flirted with numerous Protestant denominations before joining the Baptists in 1644. His first tracts, The Pilgrimage of Saints and Truth Released, appeared in 1646 and by 1649 he'd attracted a following of Ranter spiritualists in London. His most notorious Ranter prinicple was that a 'true believer is free from all traditional restraints, that sin is a product only of the imagination, and that private ownership of property is wrong,' all of which appeared in his classical Ranter tract, A Single Eye (1650).

Ranterism had its beginnings with the medieval Brethren of the Free Spirit or the Beghards, a 14th century heretical group who started the so-called Heresy of the Free Spirit. "Ranting principles" according to Gerrard Winstanley (1609?-60?), one of the groups most fervent political enemies, included a 'general lack of moral values or restraint in worldly pleasures'. Excess, excess, excess in other words; and Alehouses, brothels and pubs were apparently hotbeds of Ranter insurrection, centered primarily around London. Some were also social reformers, affiliated also with agrarian communists known as the Diggers who actually had the gall to demand of the government of England that the common lands should be returned to the common people. Their most theologically dangerous belief was that the Holy Spirit, by its nature, removed sin from even their most reprehensible acts.

Ranters and some Quakers of the period were known to cavort in the all together. They were also millenniarianists, who expected and prepared for the imminent Second Coming of Christ at any time. And yes, there was talk of orgies and streaking and all other manner of lewdness. (After all, getting naked has been big with the saints, holy men, and prophets since pre-Biblical times).

"Shock value, the rejection of worldly goods, and all men being equal in the sight of God were common motivations to undress"; so indeed the Ranters (and some Quakers even, if you can imagine such a thing) paraded nude in public. Ranters were accused (usually by their opponents) of wife swapping, sodomy, child-lust and other wanton activities which ran contrary to the societal morals of the day.

Between 1650-51, the London newspapers picked up on the Ranter movement and in January of 1651, in the City of London at Moor Lane, there was reported some 'wanton behavior at a local alehouse' and the subsequent arrests, interogations and trials were publicized outrageously (in the manner of the 'yellow journalism' of the time) but by 1652, they had exhausted media interest as a protest movement. Some scholars speculate that the pamphlets and printed sermons of the Ranters may have been the work of other sectarian and secret societies of the period.
