About this source
What it is
Wealth Against Commonwealth is a book written by muckraking journalist Henry Demarest Lloyd, published in 1894 by Harper & Brothers in New York. It grew out of essays Lloyd had written for The Atlantic Monthly about the dangers of dominating monopolies, and it focused heavily on Standard Oil, though it also discussed other companies and industrialists.
Why it matters
This book was one of the earliest major public attacks on Standard Oil and the business practices of John D. Rockefeller. It helped fuel the Progressive Movement's growing concern about monopolies in the early twentieth century, and it set an example that later muckrakers, including Ida Tarbell, would follow in their own investigations of Rockefeller's company.

- What kind of evidence do you think Lloyd needed to make his argument convincing to readers?
- How might Rockefeller himself have responded to this book, and why don't we hear his side in the title page alone?
