Conditions for Mass Displacement in Laos, 1975–1990 Student Worksheet helps students understand why thousands of Laotians, including many Hmong people, fled Laos after the Communist victory of 1975. The worksheet places Laos within the wider Indochina refugee crisis and explains how the Secret War, United States bombing, the Ho Chi Minh Trail, Pathet Lao victory, fear of reprisals, re-education camps, collectivisation and food shortages contributed to displacement.

This resource gives students a clear foundation in a topic they may know very little about. It breaks the causes of displacement into the three key areas used in the 2026 IBDP History guide: combat operations and Communist victory, persecution and fear of reprisals, and economic factors. The guide specifically places the Indochina refugee crisis under Focused study 4: Conflict and displacement, with these three areas as grounding content.

• explain how the war in Laos connected to the Vietnam War and the Ho Chi Minh Trail;
