The St. Valentine’s Day Massacre: A Historical Investigation

The St. Valentine’s Day Massacre: A Historical Investigation is a comprehensive student packet and teacher guide designed for grades 10–12. This resource examines the 1929 Saint Valentine’s Day Massacre as a case study in systems, evidence, media framing, and historical uncertainty during the Prohibition era.

Rather than presenting the event as a sensational crime story, this investigation asks students to analyze how laws, public behavior, organized crime, and media reporting interacted, and why key historical questions remain unresolved.

Students engage with nine nonfiction reading passages, structured annotation systems, evidence-tracking tools, media analysis, and writing tasks that emphasize critical reading and disciplined historical thinking.

The materials are modular and may be used as:

• A one-day Valentine’s Day lesson
• A multi-day mini-unit
• Or a selective investigation, with teachers choosing specific passages or activities
  

No prior background knowledge is required.

Instructional Focus

Students are guided to:

• Analyze cause-and-consequence relationships created by Prohibition-era policies
• Distinguish between evidence, inference, speculation, and uncertainty
• Examine how media language and framing shape public understanding
• Understand organized crime as structured power within systems, not chaos
• Recognize how historical narratives persist even without closure
