When the New Deal arrived in Wyoming, federal policy divided the state in two. In the west, the Taylor Grazing Act of 1934 brought the public range under federal regulation for the first time, creating grazing districts and permit systems that permanently reshaped who could graze and how many animals. In the east, a more disruptive transformation was underway: federal programs concluded that much of the land homesteaded on the Great Plains should never have been farmed and set about moving the people who lived there off the land, returning it to grazing.

When the stock market crashed in October 1929, Wyoming’s farms and ranches were already struggling. What followed—collapsing markets, failing banks, and years of devastating drought—pushed the state’s agricultural economy to the breaking point. The Franklin Roosevelt administration’s New Deal offered relief, but it also brought federal power directly into Wyoming’s rangeland in ways that would permanently reshape the relationship between ranchers and the land they grazed.

Before Frank Canton became notorious in Wyoming in connection with the Johnson County War, he lived an outlaw’s life as Joe Horner in Texas. Discover more about Canton’s reputation as a sheriff, his time as a stock detective for the Wyoming Stock Growers Association and his role in the invasion of Johnson County.

Frontier newspaperman Asa Mercer began the controversial Northwestern Live Stock Journal in Cheyenne in the 1880s, backing stockmen’s interests. But when prominent cattlemen-vigilantes invaded Johnson County in 1892, he attacked them stridently in his paper and later in The Banditti of the Plains, the book for which he’s best remembered.

Passed in 1934, the Taylor Grazing Act of 1934 regulated the public range around a system of grazing leases after 50 years of dispute over what to do with public lands in Wyoming and the West. The Bureau of Land Management manages most of the state’s federal lands today.  

Clabe Young came with his brothers from Texas to Wyoming Territory in the late 1870s and cowboyed for prominent ranchers including Tom Sun and Boney Earnest. The Young brothers fell under suspicion of rustling by the powerful Wyoming Stock Growers Association, whose leaders hired a Chicago detective, John Finkbone, to set the matter straight.

Tom Horn, stock detective and hired killer, was hanged in Cheyenne in 1903 for a crime he probably did not commit. He remains controversial because of lingering questions about his guilt and the nature of the trial. Horn’s death remains important as it shows the power of Wyoming’s cattle barons, once substantial, beginning at last to wane.

Grass was free and profits enormous in the cattle business in Wyoming Territory — for a while. The business dates to the 1850s, but the boom came after the Union Pacific Railroad connected Wyoming ranges to eastern markets. For a time it seemed as if every investor got rich. Finally, a weakening market and the overstocked range could not withstand two years of drought followed by a terrible winter. The big boom busted, following an economic pattern repeated many times since in an economy still based heavily on natural resources.

In April 1892, a private army of 52 cattle barons, their employees and hired Texas guns invaded Johnson County in northern Wyoming, intending to kill as many as 70 men they suspected of being rustlers or rustler sympathizers. The invaders managed to kill two men before word got out, and they were surrounded by an angry posse. Troops from nearby Fort McKinney intervened. The invaders were escorted back to Cheyenne, where they were charged but never brought to trial. The event ended in ambiguity and political division in the new state of Wyoming.
