Answer: imposing taxes on them without their approval or representation.
Explanation: King George III is considered by many to be the mentally unstable King of England from 1760-1820. The colonists were torn between loyalty to the crown and resistance because of the way he wanted to govern the affairs of the colonists and he was largely considered a tyrant.
The colonists were very angry towards king George as regards the Townshend acts which was taxation without representation as well as the taking away some of the colonists' freedom. The acts were called duties but the colonists said they were indirect taxes and were levied on imported materials like glass, lead, paint, paper and tea.
