In 1776, an economics book titled what was published to promote the concept of free enterprise?

The answer

The book is The Wealth of Nations, written by the Scottish philosopher Adam Smith and published in 1776. Its full title is An Inquiry into the Nature and Causes of the Wealth of Nations. It is widely regarded as the founding text of modern economics and the classic argument for free enterprise—an economy in which individuals and businesses make their own decisions in competitive markets with minimal government interference.

The timing is easy to remember: 1776, the same year as the American Declaration of Independence. Both documents share a spirit of individual liberty—one political, one economic.

What the book argued

Smith's central insight is the 'invisible hand.' He argued that when individuals pursue their own self-interest in a competitive market, they are led—as if by an invisible hand—to promote the good of society as a whole, even though that was not their intention. A baker bakes bread to earn a living, but in doing so feeds the community. Prices, competition, and the division of labor coordinate the economy without central planning.

From this follows the case for laissez-faire (French for 'let it be' or 'let do'): government should generally refrain from micromanaging trade and production, allowing free markets to allocate resources efficiently. Smith criticized mercantilism—the then-dominant idea that a nation's wealth was measured by its stock of gold and protected through tariffs and monopolies—and argued instead that wealth comes from productive labor, specialization, and free exchange.

Why other answers are wrong

Students sometimes confuse this with other landmark works. Karl Marx's Das Kapital (1867) and The Communist Manifesto (1848) argue nearly the opposite—critiquing capitalism, not promoting free enterprise—and appear much later. John Maynard Keynes's The General Theory (1936) advocates active government intervention, again the reverse of laissez-faire, and dates to the twentieth century. Thomas Malthus's Essay on the Principle of Population (1798) concerns population and food supply, not free enterprise. Only The Wealth of Nations matches both the 1776 date and the free-enterprise theme.

The bigger picture

Adam Smith is often called the 'father of economics' or 'father of capitalism' because The Wealth of Nations was the first comprehensive, systematic treatment of how markets create prosperity. Key ideas exam-takers should connect to it include: the division of labor (his famous pin-factory example, where specialization multiplies output), self-interest as an economic motivator, competition as a regulator of prices and quality, and free trade between nations. These principles became the intellectual foundation of the free-market, capitalist economies that spread over the following two centuries, which is exactly why the book is invoked whenever a course introduces 'free enterprise.'
