Final answer:
Thomas Jefferson accused the British government of becoming tyrannical by listing a series of abuses and usurpations in the Declaration of Independence.
Step-by-step explanation:
Thomas Jefferson provided evidence that the British government had become tyrannical by listing a series of grievances in the Declaration of Independence.
He accused the British monarch of taxing the colonists without their consent, interfering with their trade, denying them the right to trial by jury, and depriving them of the right to self-government. These intrusions on their rights led the colonists to believe that the British government was abusing its power and acting in a tyrannical manner.
