What was the main argument presented in Common Sense for independence?

The main argument presented in Common Sense for independence was that the American colonies should break away from British rule and declare their independence. Thomas Paine argued that it was simple common sense for the colonies to govern themselves and that the British monarchy was inherently corrupt. He criticized the monarchical system and argued for the establishment of a democratic system in which the people have the power to govern themselves. Paine also highlighted the economic disadvantages of remaining under British rule and the need for the colonies to have control over their own resources and trade. Essentially, Common Sense made a strong case for why independence was not only necessary but also the logical and rational choice for the American colonies.
