http://en.wikipedia.org/wiki/Royal_Proclamation_of_1830

In 1830 a Royal Proclamation was issued by King William IV of the United Kingdom "for the encouragement of Piety and Virtue, and for the preventing and punishing of Vice, Profaneness, and Immorality." Copies of the Proclamation were sent to all the Church of England incumbents, for them to read out in Church.

The Proclamation commanded local judges, mayors, sheriffs and magistrates "to be vigilant and strict in the discovery and the eventual prosecution and punishment of all persons who shall be guilty of excessive drinking, blasphemy, profane swearing and cursing, lewdness, profanation of the Lords' day, or other dissolute, immoral or disorderly practices ... and that by their own good and virtuous lives and conversations they do set good examples to all such as are under their authority."

WILLIAM R.

WE most seriously and religiously considering that it is an indispensable Duty on Us to be careful, above all other Things, to preserve and advance the Honour and Service of Almighty God, and to discourage and suppress all Vice, Profaneness, Debauchery, and Immorality, which are so highly displeasing to God, so great a Reproach to our Religion and Government, and (by means of the frequent ill Examples of the Practices thereof) have so fatal a Tendency to the Corruption of many of Our loving Subjects, otherwise religiously and virtuously disposed, and which (if not timely remedied) may justly draw down the Divine Vengeance on Us and Our Kingdom:

YOU hear so many strange things about British Israelites. Who are they? where did this Anglo-Israel teaching have its origins? Are they a crazy racist cult, a new American sect? Opponents of Anglo-Israel, having little or no Scriptural evidence to refute our teachings, prefer to frighten sincere seekers for truth by seeking to smear British-Israel with the biggest tar brush possible. A favourite method seems to be that of claiming that the Anglo-Israel teaching originated with the writings of the deranged Richard Brothers, who was for a time confined to a lunatic asylum in the late eighteenth/early nineteenth century. Now I feel sure that you the reader would prefer the truth, and so we will trace the origins of our message and tell you of the many distinguished clergymen, evangelists and preachers of many diverse Protestant denominations who have held to our beliefs, as well as many members of our own British Royal Family.

Let us be clear about one thing, there was a knowledge of and writings about the Israel Identity of the Celto-Anglo Saxon and related peoples long before poor Richard Brothers ever stumbled upon this truth.
