In Common Sense, Thomas Paine argued that the British had helped the colonies only to

exploit and oppress them. Paine claimed that the British government had no legitimate authority over the colonies and that the monarchy was an outdated and corrupt institution. He argued that it was time for the American colonies to break away from British rule and establish their own independent government. Paine's arguments in Common Sense played a significant role in convincing many Americans to support the idea of independence and ultimately contributed to the start of the American Revolutionary War.
