Pre-20th Century:

  • Ancient Times: The region where Chongqing is located has a rich history dating back thousands of years. It has been inhabited since ancient times, with evidence of human presence found in archaeological sites throughout the area. The region's strategic location along the Yangtze River and its surrounding fertile land made it an attractive area for settlement and trade.

20th Century:

  • 1911: With the fall of the Qing Dynasty and the establishment of the Republic of China, Chongqing (then known as Chungking) became a part of the new republic. It served as an important administrative and commercial center in the southwestern region of China.
  • 1938-1945: During the Second Sino-Japanese War, Chongqing gained international prominence as the provisional capital of China. The Chinese government, led by Chiang Kai-shek, relocated the capital to Chongqing to escape the advancing Japanese forces. The city's mountainous terrain and location inland from the coast provided a degree of protection from Japanese air raids.
  • 1949: After the end of World War II and the victory of the Chinese Communist Party in the Chinese Civil War, Chongqing became a municipality under the direct control of the central government of the newly established People's Republic of China. The city played a significant role in the early years of the PRC's development as it recovered from the ravages of war.
