The major world event sparked by the disproportionate taxation of American colonies by Britain was the American Revolution. Rising discontent among colonists due to taxes imposed by the British Parliament without colonial representation, such as the Stamp Act and the Tea Act, fueled revolutionary sentiments. Colonists viewed these taxes as unjust and largely protested against "taxation without representation." The tensions culminated in events like the Boston Tea Party and the formation of the Continental Congress. The revolution ultimately led to the Declaration of Independence in 1776, as the colonies sought to break free from British control and establish their sovereignty.
