Progress and Poverty

Progress and Poverty, George's first book, sold several million copies, exceeding all other books sold in the United States except the Bible during the 1890s. It helped spark the Progressive Era and a worldwide social reform movement around an ideology now known as 'Georgism'. Jacob Riis, for example, explicitly marks the beginning of the Progressive Era awakening as 1879 because of the date of this publication. The Princeton historian Eric F. Goldman wrote this about the influence of Progress and Poverty:

For some years prior to 1952 I was working on a history of American reform and over and over again my research ran into this fact: an enormous number of men and women, strikingly different people, men and women who were to lead 20th century America in a dozen fields of humane activity, wrote or told someone that their whole thinking had been redirected by reading Progress and Poverty in their formative years. In this respect no other book came anywhere near comparable influence.

Progress and Poverty had perhaps even a larger impact around the world, in places such as Denmark, the United Kingdom, Australia, and New Zealand, where George's influence was enormous. Contemporary sources and historians claim that in the United Kingdom, a vast majority of both socialist and classical liberal activists could trace their ideological development to Henry George. George's popularity was more than a passing phase; even by 1906, a survey of British parliamentarians revealed that the American author's writing was more popular than Walter Scott, John Stuart Mill, and William Shakespeare.] In 1933, John Dewey estimated that Progress and Poverty "had a wider distribution than almost all other books on political economy put together."
