Killers of the Flower Moon tells the story of the Osage Nation, who became some of the wealthiest people per capita in the world after oil was discovered on their Oklahoma land in the early 1900s. As their wealth grew, so did a wave of suspicious deaths targeting Osage members. The book traces the slow, flawed investigation that eventually uncovered a conspiracy involving white settlers, local officials, and even Osage Nation members who had allied with the perpetrators. Use this overview to ground your class discussion prep by linking each event to a core theme like power or injustice.
The book’s central themes include systemic violence against Indigenous communities, the corrupting power of wealth, and institutional failure to protect marginalized groups. Each theme is woven into the narrative through specific events, from the Osage’s loss of land rights to the FBI’s bungled investigation. Circle one theme in your notes and label three events that illustrate it to prepare for essay prompts.
The book is set during a time when the US government forced Indigenous nations to accept allotment of their land, which made it easier for white settlers to acquire Osage oil rights. This context explains why the Osage were vulnerable to exploitation and violence. Look up one federal policy related to Indigenous land allotment to add depth to your analysis.
Avoid framing the book as a true crime story. Instead, focus on its role as a historical expose of Indigenous trauma and systemic injustice. Use specific events from the book as evidence, and tie each point back to your thesis. Write a practice body paragraph that centers the Osage Nation’s perspective alongside white characters to refine your approach.
Come to class with one question that ties a book theme to a modern issue, like missing and murdered Indigenous women. Bring two specific examples from the book to support your point. Practice explaining your question and examples in 90 seconds to ensure you can articulate them clearly during discussion.
Don’t focus only on individual perpetrators. The book’s strength lies in its exposure of systemic injustice, not just individual greed. Don’t ignore the Osage Nation’s agency; they advocated for themselves long before the FBI got involved. Jot down these two mistakes in your notes and add a reminder to avoid them during quiz prep.
