When North and South Vietnam were reunified under communist rule in 1975, hundreds of thousands of people decided they could not stay.
Over the next 15 years, more than 1.5 million Vietnamese left the country — most of them by sea.
These refugees became known as the boat people. They crammed onto small fishing boats, often unseaworthy, and faced pirates, storms, and starvation in the South China Sea before reaching camps in Malaysia, Thailand, Hong Kong, or the Philippines.
Not one refugee experience — many: The exam inquiry question asks how was displacement experienced by different groups? The key word is different. South Vietnamese ex-soldiers, ethnic Chinese traders, and highland farmers all left Vietnam for different reasons, faced different dangers, and were treated differently once they arrived. A good source-based answer never treats 'Vietnamese refugees' as one uniform group.
Many early boat people (1975-1978) had worked for the former South Vietnamese government or the US-backed army. They feared imprisonment in the new regime's re-education camps, so they left as soon as they could.
- The Hoa (ethnic Chinese) — around 1 million ethnic Chinese lived in Vietnam, many as traders in Cholon (Saigon's Chinatown). After Vietnam's 1978-79 border war with China, the Vietnamese government treated the Hoa as a security risk, closed their businesses, and pushed them out — over 250,000 fled by boat or were forced across the land border into China.
- The Montagnard — highland peoples of Vietnam's Central Highlands (also called the Degar), many of whom had fought alongside US and South Vietnamese forces during the war. After 1975 they faced land seizure and persecution as 'collaborators', and many fled overland into Cambodia or Thailand rather than by sea.
Notice the pattern: the Hoa were pushed out for their ethnicity and economic role; the Montagnard were punished for wartime loyalty and land conflict. Same country, same years, very different push factors.
Reading a source's CONTENT (Q1 skill): Imagine a source is a 1979 interview with a Hoa shopkeeper describing having her shop confiscated in Cholon. Its content directly answers 'how was displacement experienced?'
It tells you WHAT happened to her
- Loss of livelihood
- Forced departure
- Fear of the new state
Using it for Q1: Quote or paraphrase specific details (the shop, the date, the fear) and link them explicitly to the inquiry question, rather than just summarising 'Vietnam was hard for refugees'.

Cambodia's displacement crisis was driven by one of the most extreme regimes of the twentieth century. The Khmer Rouge took power in April 1975 and immediately emptied the cities, forcing millions into rural labour camps.
The Khmer Rouge aimed to build a purely agrarian, classless society. Anyone linked to the old government, the educated, or ethnic and religious minorities was treated as a threat. Roughly 1.5 to 2 million Cambodians died from execution, starvation, and overwork — a genocide that historians call the Killing Fields.
Who the Cham are: The Cham are Cambodia's Muslim minority, descended from the old Champa kingdom. The Khmer Rouge singled them out especially harshly.
How the Cham were targeted
- Their religion, language, and dress were banned
- Their mosques were destroyed
- Historians estimate around half the Cham population died under the regime — a higher proportional death rate than for Cambodians as a whole
Why the Cham matter to this inquiry: The Cham are a crucial case for showing that displacement and persecution fell unevenly across groups.
Displacement from Cambodia had two waves. From 1975-78, small numbers escaped the Khmer Rouge itself, crossing minefields and jungle into Thailand. After Vietnam invaded Cambodia in December 1978 and toppled Pol Pot, a much larger wave fled — this time escaping both the chaos of war and continuing Khmer Rouge guerrilla activity along the Thai border.
| Group | Main threat | When they mostly fled |
|---|---|---|
| Cambodians (general) | Forced labour, starvation, execution under the Khmer Rouge | 1975-79, then 1979-81 after the Vietnamese invasion |
| Cham Muslims | Targeted religious/ethnic persecution — banned faith and language | Throughout 1975-79; survivors fled post-1979 |
| Former officials/educated Cambodians | Executed as 'enemies of the revolution' | Rarely escaped; those who did fled early, 1975-76 |
Reading CONTEXT (Q2 skill): A source's context is who made it, when, why, and for whom. Two sources can both be useful, but for different things — always ask what the origin and purpose let a source show well, and what it might leave out.
A Cham survivor's memoir (published in the 1990s)
- Purpose might be to record memory and educate
A UNHCR refugee-camp report (Thailand, 1979)
- Purpose is to log numbers and secure international aid

Laos is often the least remembered part of the Indochina crisis, but it produced a huge refugee outflow relative to its small population.
When the communist Pathet Lao took control in December 1975, around 10% of the entire Laotian population eventually fled — mostly on foot or by crossing the Mekong River into Thailand.
Lowland Lao who had worked for the former royalist government feared persecution and re-education, much like South Vietnamese officials. But the group facing the greatest danger were the highland peoples of Laos — especially the Hmong.
Why the Hmong were specifically targeted: The Hmong were treated as traitors and enemies not for their ethnicity alone, but for a specific political and military choice: their wartime alliance with the USA.
From ally to target
The 'Secret Army'
During the Vietnam War, the CIA secretly recruited and armed tens of thousands of Hmong fighters, under General Vang Pao's leadership.
Fighting in Laos
They fought the Pathet Lao and North Vietnamese forces.
1975
When the communists won, the Hmong were treated as traitors and enemies for that alliance.
Recruited by the CIA → fought the communists → punished in 1975
Thousands of Hmong were killed in reprisals or died fleeing through jungle and across the Mekong. Others hid in the mountains for years, some fighting a low-level insurgency against the new government into the 1980s. Survivors reached camps in Thailand, and many were eventually resettled in the USA, France, or Australia — a direct consequence of who their wartime ally had been.
Hmong (highland Laos)
- Targeted for wartime alliance with the CIA against the Pathet Lao
- Many fled overland through mountains and jungle, on foot
- Some continued armed resistance into the 1980s
Montagnard (highland Vietnam)
- Targeted for wartime alliance with US/South Vietnamese forces
- Many fled overland into Cambodia or Thailand
- Faced land seizure as well as political persecution
Reading PERSPECTIVES (Q3 skill): Picture three sources: a Hmong veteran's oral testimony, a Pathet Lao government statement calling the Hmong 'bandits', and a US resettlement agency's 1980 report. Each gives a different perspective on the same event.
| Source | Its perspective |
|---|---|
| Hmong veteran's testimony | Centres suffering and betrayal |
| Pathet Lao government statement | Justifies persecution as necessary security |
| US resettlement agency's report | Frames Hmong refugees as a humanitarian and diplomatic obligation |
What a strong Q3 answer does: A strong Q3 answer explains WHY these perspectives differ (origin, purpose, audience) — not just that they differ.
