The Stamp Act was an Act requiring stamps of varying values to be affixed to legal documents, and was intended as a means of raising revenue. The Act was passed by Lord Rockingham's Government on March 22nd 1765. It formed part of Grenville's scheme for the taxation of the Colonies, requiring all deeds, receipts for money etc. to be written on stamped paper, the receipts going to revenue. It was one of the chief causes of the American War Of Independence, the American Colonies highly resenting taxation without representation. It was repealed on March 18th 1766, but was replaced by a Declaratory Act formally asserting the right of Parliament to tax colonies. Research Stamp Act
