Why did the Communists undertake the Long March? to escape from the Nationalist forces to attack the Nationalist forces to drive the Japanese from China to drive Western powers from China

The Communists undertook the Long March to escape from the Nationalist forces. The Nationalist Forces (called the Kuomintang) were pursuing the Communists to drive them out of the south, so the Long March (which consisted of a few marches) of communists went to north and western China, where they gained many supporters of their own party along the way.
