The second Sino-Japanese war took place from 1937 to 1945. The war broke out because of Chinese resistance against Japanese influence in its territory.
The war wasn’t declared until December 9, 1941, and it was divided into three phases:
- A period of rapid Japanese advance until 1938
- A period of a stalemate until 1944
- The final period where allied forces helped the Chinese to fight Japan.
In the 20th Century, Japan took control of China’s cities and ports such as Manchuria, Manchukuo, Suiyuan, Shensi, Shantung, and others.
While Japan was doing this, Chinese ruler, Chiang, did not oppose, instead he campaigns against communism in China.
In 1936, under the pressure of his men, he was forced to team up with the nationalist government to fight back Japan.
The war continued; Japan captured more states and made them a puppet. But Chinese rulers were not willing to surrender or negotiate.
Japan continues to push northward and westward of China while they took control of more ports.
The war went on, until in 1944 to 1945, where China received military support, financial assistance, and training from the United States to fight Japan.
It didn’t take that long until China reclaimed back the states which were under Japan’s influence. That’s how the Second Sino-Japanese war started and ended.
