Thomas Paine was born in1737 at Thetford, Norfolk in England, as a son of a Quaker. He immigrated to America in 1774. There he published works criticising the slavery and supporting American independence. He became very popular but returned to England where he became involved in the French Revolution. After that he returned to America where he died in 1802

The revolution of America presented in politics what was only theory in mechanics. So deeply rooted were all the governments of the old world, and so effectually had the tyranny and the antiquity of habit established itself over the mind, that no beginning could be made in Asia, Africa, or Europe, to reform the political condition of man. Freedom had been hunted round the globe; reason was considered as rebellion; and the slavery of fear had made men afraid to think. But such is the irresistible nature of truth, that all it asks,- and all it wants,- is the liberty of appearing. The independence of America, considered merely as a separation from England, would have been a matter but of little importance, had it not been accompanied by a revolution in the principles and practice of governments. She made a stand, not for herself only, but for the world, and looked beyond the advantages herself could receive.
