The Great Plains stretch across a vast portion of the central United States. Given the frequent mention of the Plains in APUSH, I have produced this post. It’s designed to offer my students a comprehensive overview of this significant region, all in one convenient location.

First, a map of the Great Plains:

1491–1800:

Prior to the arrival of Europeans, the Great Plains were home to a variety of indigenous tribes, including the Lakota, Cheyenne, Comanche, and Pawnee. These tribes were primarily nomadic, relying on hunting, gathering, and fishing for their livelihoods. The arrival of Europeans in the 16th century brought diseases such as smallpox that devastated many of these tribes, with some estimates suggesting that up to 90% of the indigenous population on the Great Plains died from these diseases.

The Spanish were among the first Europeans to introduce horses to the Americas, and the introduction of horses had a significant impact on the Native American tribes living on the Great Plains. The horse allowed these tribes to become more mobile and efficient in hunting and warfare, which helped to shape the culture and traditions of the Plains tribes.

The buffalo, or American bison, was a crucial resource for the Native American tribes of the Great Plains, providing food, clothing, and shelter. The Plains tribes relied on the buffalo for their survival and developed a deep reverence for the animal.

1800-1900:

In the early 1800s, the region was largely unexplored by Americans, with the exception of a few fur trappers and traders.

However, in 1803, the United States acquired the Louisiana Purchase, which included much of the Great Plains region. This acquisition paved the way for westward expansion and the settlement of the Great Plains.

Throughout the 1800s, the Great Plains were the site of significant conflicts between Native American tribes and European settlers. The United States government signed numerous treaties with Native American tribes during this time, but many were broken or ignored as settlers continued to move westward.

One significant event during this time was the Mexican-American War of 1846–1848, which resulted in the acquisition of even more land in the western United States, including parts of the Great Plains. The war also led to increased tensions between the United States and Mexico, which would have lasting impacts on the region.

As the 1800s progressed, the Great Plains became a center for the expansion of agriculture in the United States. Farmers began to use new technologies like barbed wire and windmills to settle the land and increase productivity. The development of railroads also made it easier to transport goods and people across the region.

However, the growth of agriculture and settlement came at a significant cost to Native American tribes. The displacement of Native Americans from their traditional lands and the destruction of buffalo herds, a primary resource for many tribes, led to widespread poverty and suffering.

In addition, the arrival of European settlers in the Great Plains led to conflicts with Native American tribes. These conflicts often turned violent, with both sides suffering significant casualties. The United States government also pursued a policy of forced assimilation during this time, with the establishment of boarding schools for Native American children and the forced removal of Native American children from their families.

Overall, the 19th century was a period of significant change and conflict in the history of the Great Plains. While the expansion of agriculture and settlement brought economic growth and prosperity to the region, it also had devastating effects on Native American tribes, who were forced to adapt to new ways of life or face displacement and marginalization.

1900s-2000s

The 20th century brought about significant changes to the Great Plains, as the region continued to adapt and evolve in response to economic, political, and social changes.

One significant event during this time was the discovery of oil in the Great Plains region. The first significant discovery was made in Texas in 1901, and soon after, oil booms were seen in other parts of the Great Plains, including Oklahoma, Kansas, and North Dakota. The oil industry brought significant economic growth and prosperity to the region, but also had negative impacts on the environment and on local communities.

Another major development during this time was the Dust Bowl, a severe environmental disaster that occurred in the Great Plains during the 1930s. Drought, coupled with poor land management practices, led to massive dust storms that destroyed crops, homes, and livelihoods. The Dust Bowl had a significant impact on the people and communities of the Great Plains, leading to widespread poverty and migration to other parts of the country.

The mid-20th century saw significant changes in agriculture as well, as technological advancements and government policies led to increased productivity and efficiency. The use of chemical fertilizers, pesticides, and other technologies revolutionized farming practices in the Great Plains, but also had negative impacts on the environment and on human health.

Throughout the 20th century, the Great Plains continued to be a site of political and social conflicts, particularly around issues of land ownership, water rights, and environmental protection. Native American tribes continued to fight for recognition of their sovereignty and land rights, and environmentalists advocated for protections of the region’s unique and fragile ecosystems.

In recent decades, the Great Plains have also been impacted by climate change, with rising temperatures, changing precipitation patterns, and increased frequency of extreme weather events. These changes have had significant impacts on the region’s agriculture, water resources, and communities.

Despite the challenges and conflicts of the 20th century, the Great Plains remain a vital and important region of the United States, with a rich history and diverse culture. Today, the region continues to adapt and evolve in response to new challenges and opportunities, while maintaining its unique character and spirit.

2000-Present

In recent years, the Great Plains have faced a variety of challenges, including declining population, economic inequality, and environmental degradation. Climate change has led to more frequent droughts and wildfires, and the region is also facing the impacts of oil and gas extraction, including the risks of spills and contamination of groundwater. The Great Plains are also home to a number of Native American communities, who continue to face challenges related to land rights, health care, and economic opportunity.

Word, Terms, and Phrases

The American Bison

The American Bison, also known as the buffalo, once roamed the Great Plains of North America in enormous herds, numbering in the millions. The bison were essential to the lives of many Native American tribes, who depended on them for food, clothing, and shelter.

The bison were well adapted to the Great Plains environment and were able to survive harsh winters and droughts. They were also able to move great distances to find food and water, which allowed them to thrive in the grasslands.

However, in the 19th century, the bison population began to decline rapidly due to overhunting by European settlers. The settlers saw the bison as a threat to their crops and a hindrance to the expansion of their settlements, and they hunted the animals for sport as well.

By the late 1800s, the bison population had dwindled to just a few hundred animals. Fortunately, some individuals and organizations recognized the importance of the bison and worked to preserve the species.

One of the most famous conservationists was William Hornaday, who founded the American Bison Society in 1905. The society worked to establish protected areas for bison and to breed the animals in captivity to increase their numbers.

Today, the bison population has rebounded to around 500,000 animals, although most of them are raised for meat rather than living wild on the Great Plains. Nevertheless, the bison remains an important symbol of the American West and a reminder of the importance of conservation efforts.
