Key topic 2: Development of the Plains, c1862–c1876 - 3 Changes in the…

The idea

The expansion of railroads, the cattle industry, and gold prospecting severely disrupted the traditional ways of life of Indigenous peoples on the Plains. Railroad construction divided buffalo herds, brought hunters who decimated the buffalo population, and encouraged further white settlement on tribal lands. The booming cattle industry led to ranchers driving cattle across Indigenous territories, competing with buffalo for grazing land and water, and often violating treaty agreements. Furthermore, gold prospecting, particularly in areas like the Black Hills of Dakota, triggered massive influxes of miners into sacred and treaty-protected lands. This relentless encroachment destroyed the buffalo-dependent economy of the Plains tribes and provoked defensive conflicts, ultimately forcing Indigenous peoples onto increasingly restricted reservations.

What earns the marks

• Explain how railroad construction physically divided the Plains, disrupting buffalo migration routes and facilitating mass hunting.
• Describe the impact of the cattle industry, including competition for grazing land and the trespassing of cattle drives on Indigenous territory.
• Analyse the consequences of gold prospecting, such as the Black Hills gold rush, which led to the violation of the Fort Laramie Treaty.
• Evaluate how these three factors combined to destroy the buffalo-based economy and force Indigenous peoples onto reservations.

Common mistakes and how to put them right

• Treating the three factors as isolated events.

  Put it right: Explain how railroads, cattle, and gold prospecting simultaneously and cumulatively pressured Indigenous lands.

• Focusing only on the physical conflict.

  Put it right: Ensure you discuss the ecological and economic impact, particularly the destruction of the buffalo herds.

• Stating that Indigenous peoples willingly gave up their lands.

  Put it right: Emphasise that lands were often taken in violation of existing treaties due to economic pressures like gold rushes.

Exam tips

• Link the destruction of the buffalo directly to the railroads, as trains brought the hunters who slaughtered them for hides.
• Use the Black Hills gold rush as a specific example of how economic interests (gold) overrode legal agreements (treaties) with Indigenous peoples.
• When assessing impact, consider both the immediate loss of land and the long-term destruction of the nomadic, buffalo-hunting way of life.
