How did the arrival of Nationalist refugees affect Taiwan after 1949?

The arrival of approximately 1.5 to 2 million Nationalist refugees, including government officials, military personnel, and supporters, fundamentally transformed Taiwan after 1949. This migration created significant social and political tensions between the new arrivals, known as waishengren, and the established population, or benshengren (primarily Fukienese and Hakka people).1234

The impact of this influx included:

• Authoritarian Rule: The Kuomintang (KMT) imposed martial law, which lasted until 1987. This regime banned opposition parties, enforced strict censorship, and utilized the military to suppress dissent, leading to a period of political violence and fear known as the White Terror.15
• Political and Social Stratification: The KMT elite staffed the highest levels of government, the military, and the education system with mainlanders. This marginalized the local Taiwanese population, who were often viewed with suspicion by the new government.63
• Cultural Policy: The government enforced a Mandarin-language policy in schools, forbidding the use of native dialects like Taiwanese Hokkien, and omitted sensitive historical events, such as the 228 Incident, from school curricula.1

While these tensions persisted for decades, they gradually evolved through urbanization and social change, eventually giving way to Taiwan's democratization.6
