Thomas Paine 
Common Sense [EPUB ebook] 

COMMON SENSE is a pamphlet written by Thomas Paine in 1775-76 that inspired people in the Thirteen Colonies to declare and fight for independence from Great Britain in the summer of 1776. The pamphlet explained the advantages of and the need for immediate independence in clear, simple language. It was published anonymously on January 10, 1776, at the beginning of the American Revolution and became an immediate sensation. It was sold and distributed widely and read aloud at taverns and meeting places.
Washington had it read to all his troops, which at the time had surrounded the British army in Boston. In proportion to the population of the colonies at that time (2.5 million), it had the largest sale and circulation of any book published in American history.
