  In the final phases of the Chinese Civil War, the People's Liberation Army seized control of the city peacefully on 31 January 1949 in the course of the Pingjin Campaign. On 1 October that year, Mao Zedong announced the creation of the People's Republic of China from atop Tian'anmen. He restored the name of the city, as the new capital, to Beijing, a decision that had been reached by the Chinese People's Political Consultative Conference just a few days earlier.
  
  In the 1950s, the city began to expand beyond the old walled city and its surrounding neighborhoods, with heavy industries in the west and residential neighborhoods in the north. Many areas of the Beijing city wall were torn down in the 1960s to make way for the construction of the Beijing Subway and the 2nd Ring Road.
  
  During the Cultural Revolution from 1966 to 1976, the Red Guard movement began in Beijing and the city's government fell victim to one of the first purges. By the autumn of 1966, all city schools were shut down and over a million Red Guards from across the country gathered in Beijing for eight rallies in Tian'anmen Square with Mao. In April 1976, a large public gathering of Beijing residents against the Gang of Four and the Cultural Revolution in Tiananmen Square was forcefully suppressed. In October 1976, the Gang was arrested in Zhongnanhai and the Cultural Revolution came to an end. In December 1978, the Third Plenum of the 11th Party Congress in Beijing under the leadership of Deng Xiaoping reversed the verdicts against victims of the Cultural Revolution and instituted the "policy of reform and opening up."
  
  Since the early 1980s, the urban area of Beijing has expanded greatly with the completion of the 2nd Ring Road in 1981 and the subsequent addition of the 3rd, 4th, 5th and 6th Ring Roads. According to one 2005 newspaper report, the size of newly developed Beijing was one-and-a-half times larger than before. Wangfujing and Xidan have developed into flourishing shopping districts, while Zhongguancun has become a major center of electronics in China. In recent years, the expansion of Beijing has also brought to the forefront some problems of urbanization, such as heavy traffic, poor air quality, the loss of historic neighborhoods, and a significant influx of migrant workers from less-developed rural areas of the country. Beijing has also been the location of many significant events in recent Chinese history, principally the Tiananmen Square protests of 1989. The city has also hosted major international events, including the 2008 Summer Olympics and the 2015 World Championships in Athletics, and the 2022 Winter Olympics, making it the first city to ever host both Winter and Summer Olympics.
