The Wealth of Nations was published 9 March 1776, during the Scottish Enlightenment and the Scottish Agricultural Revolution. It influenced a number of authors and economists, as well as governments and organizations. For example, Alexander Hamilton was influenced in part by The Wealth of Nations to write his Report on Manufactures, in which he argued against many of Smith's policies. Interestingly, Hamilton based much of this report on the ideas of Jean-Baptiste Colbert, and it was, in part, Colbert's ideas that Smith responded to with The Wealth of Nations.
Many other authors were influenced by the book and used it as a starting point in their own work, including Jean-Baptiste Say, David Ricardo, Thomas Malthus and, later, Ludwig von Mises. The Russian national poet Aleksandr Pushkin refers to The Wealth of Nations in his 1833 verse-novel Eugene Onegin.
The Wealth of Nations was the product of seventeen years of notes, and observation of conversation among economists of the time concerning economic and societal conditions during the beginning of the Industrial Revolution, and took Smith ten years to produce. The result, An Inquiry to the Wealth of Nations, was a treatise which sought to offer a practical application for reformed economic theory to replace the mercantilist and physiocratic economic theories that were becoming less relevant in the time of industrial progress and innovation. It provided the foundation for new economists, politicians, mathematicians, biologists, and thinkers of all fields to build upon. Irrespective of historical influence, The Wealth of Nations represented a clear shift in the field of economics, comparable to Sir Isaac Newton's Principia Mathematica for physics, Antoine Lavoisier's Traité Élémentaire de Chimie for chemistry, or Charles Darwin's On the Origin of Species for biology.
Five editions of The Wealth of Nations were published during Smith's lifetime: in 1776, 1778, 1784, 1786, and 1789. Numerous editions appeared after Smith's death in 1790. To better understand the evolution of the work under Smith's hand, a team led by Edwin Cannan collated the first five editions. The differences were published along with an edited sixth edition in 1904. They found minor but numerous differences (including the addition of many footnotes) between the first and the second editions, both of which were published in two volumes. The differences between the second and third editions, however, are major: In 1784, Smith annexed these first two editions with the publication of Additions and Corrections to the First and Second Editions of Dr. Adam Smith’s Inquiry into the Nature and Causes of the Wealth of Nations, and he also had published the three-volume third edition of the Wealth of Nations, which incorporated Additions and Corrections and, for the first time, an index. Among other things, the Additions and Corrections included entirely new sections. The fourth edition, published in 1786, had only slight differences from the third edition, and Smith himself says in the Advertisement at the beginning of the book, "I have made no alterations of any kind." Finally, Cannan notes only trivial differences between the fourth and fifth editions — a set of misprints being removed from the fourth and a different set of misprints being introduced.
