The People's Republic of China was established after winning the civil war in 1949 by which political party?

• A. The Kuomintang (Nationalist Party)
• B. The Chinese Communist Party (led by Mao Zedong)
• C. The Democratic Progressive Party
• D. The Socialist Party of China

Answer: (B)

The main idea here is recognizing which party won the Chinese Civil War and proclaimed a new government on the mainland in 1949. The party that established the People's Republic of China was the Chinese Communist Party, led by Mao Zedong. After years of fighting the Kuomintang, the Communist forces gained the upper hand, especially by winning support in rural areas and implementing land-reform measures, and they finally proclaimed the PRC in 1949. Meanwhile, Chiang Kai-shek and the Kuomintang retreated to Taiwan, where they continued the government as the Republic of China. The other options don’t fit: the Democratic Progressive Party is a modern Taiwan-based party that didn’t win the civil war or found the PRC, and the Socialist Party of China isn’t the party that led to the founding of the PRC.
