In 1767 "Champagne Charley" Townshend persuaded Parliament to pass the Townshend Acts. These acts put a light import duty on such things as glass, lead, paper, and tea. The acts met slight protest from the colonists, who found ways around the taxes such as buying smuggled tea. Due to its minute profits, the Townshend Acts were repealed in 1770, except for the tax on tea. The tax on tea was kept to keep alive the principle of Parliamentary taxation. The episode served as another important step in the coming of the American Revolution.
