The slogan "no taxation without representation" was coined by the American colonists of the original 13 colonies, beginning around 1750. The idea behind the words related to taxing the colonies on imports such as sugar and tea.
The English Bill of Rights of 1689 determined taxation of its citizens without representatives in British Parliament illegal. However, the British taxed the colonists, who had no representative in Parliament. In 1773, colonists threw shiploads of taxed tea into the Boston Harbor, in a protest called The Boston Tea Party. The Tea Party escalated differences between the colonists and the British king, and was one of the main precursors to the American Revolutionary War.
