The Stamp Act
On March 22, 1765, the British Parliament passed an odious piece of legislation known as the Stamp Act. It imposed a tax on every piece of paper used by colonists in America, including all legal documents, licenses, newspapers and other publications... and even playing cards.
The colonists were outraged by this "taxation without representation" and launched massive protests. After a decade of appeals accomplished nothing, Patrick Henry urged Virginia's House of Burgesses to adopt his Stamp Act Resolves. When the legislators approved four of the resolutions, Virginia Governor Fauquier (who was appointed by the King) ordered the assembly dissolved.
The next day, on March 23, 1775, Henry gave his famous speech, which ended with, "I know not what course others may take, but as for me, Give me Liberty or Give me Death." Within a month, Britain and the colonies were at war, Fauquier fled his post, and Patrick Henry was named Governor of Virginia.
I think you know how the story ends.
