The Sino-French war was a massive event in China's history and the Qing Dynasty. The Nationalist movement in China was sparked during the war, which didn't help the Qing Dynasty at all. The nationalist movement was trying to change the entire way that China was ruled. To many lives were taken during this war. Even though China, France and Vietnam came to an agreement in the end, I believe that there was no real reason to go to war. This war definitely influenced the decline of the Qing Dynasty.
