In Common Sense, he called England’s King George III “the Royal Brute of Great Britain,” who “hath wickedly broken through every moral and human obligation, trampled nature and conscience beneath his feet, and by a steady and constitutional spirit of insolence and cruelty procured for himself a universal hatred.” Thomas Paine’s Common Sense, published in 1776. Paine wasn’t just contemptuous of one particular British ruler but of monarchs in general.
