What No taxation without representation is a reaction of?

"No taxation without representation" is a reaction to the British government's imposition of taxes on the American colonies without granting them a voice in Parliament. It encapsulated the colonists' belief that it was unjust to be taxed by a government in which they had no elected representatives. This sentiment fueled growing discontent and ultimately contributed to the American Revolution, as colonists sought to assert their rights and autonomy.
