How did different groups in the West experience U.S. expansion?
Second edition. January 2021.

At the dawn of the nineteenth century, North America was home to diverse Native American, European, and African groups. These groups and individuals experienced U.S. territorial expansion in very different ways. Groups betrayed and fought each other, but they also worked to understand each other across a chasm of cultural difference. In later years, people in the United States would tell a history of this period that left out the violence and racism, as well as the mutual adaptation, that accompanied this conquest. In recent years, scholars have worked to reexamine the history of the West by focusing on Native American groups. With limited sources, they have pieced together histories that do not generalize the experiences of Native Americans, and that accurately portray the complicated interactions that occurred in the West. 


Westward Expansion: A New History looks at this reexamined history from two historical perspectives. First, students explore U.S. expansion from a broad perspective by considering the major events and policies that accompanied U.S. growth in the nineteenth century. Students then explore this history on a local level using groundbreaking research on the effects of U.S. expansion on groups in southern Arizona. This case study is not emblematic of the entire West; rather, it allows students to understand the complicated and violent ways in which U.S. expansion affected specific individuals and communities.

Legend as an Historical Source

In this lesson students examine a Kiowa legend about smallpox and consider its value as an historical source.

Cherokee Nation v. Georgia, 1831

After examining U.S. Supreme Court Justice Marshall's decision on the status of Indians in the United States, students analyze the government's role in determining the status of Native American groups.

Geography from Four Perspectives

Students practice map-reading skills and connect geography to historical events. Students use maps to explore claims that different groups made on lands in southern Arizona.

Indian Primary Sources from Arizona

Students use O'odham calendar sticks as primary sources to consider the connection between local history and the wider history of North America.

Considering the Perspectives

Working cooperatively, students research and present multiple perspectives about issues at play in southern Arizona in 1871, and consider the ways U.S. settler colonialism affected different Native groups, U.S. settlers, and Mexican Americans in the region.

Rewriting History

In this activity, students analyze two accounts from 1871 of the attack at Camp Grant and consider the effects of missing voices in history.

Historical Memory—Aravaipa Canyon

Students design an exhibit for the Aravaipa Canyon Visitor's Center and reflect on the effects of U.S. westward expansion and the ways that people think about this history.

Assessment Using Documents — The Decline of the Buffalo

Students analyze primary and secondary sources in order to answer questions about the social, political, and economic factors that led to the decline of the buffalo population.
