Which historical development is most closely associated with this poster

the Cultural Revolution

Explanation:

Cultural Revolution was the movement that urged on preserving communism and the Communist party in China with the leader Mao Zedong on the top. It wanted to change the capitalistic and traditional elements of Chinese ideas and life into the ones that are always connected with Mao’s character and thought. This was titled Maoism.  

The propaganda posters of the kind depicted above were common during the period. They were glorifying Mao and his influence on the people, soldiers, and culture of the country. While we cannot understand the text if we do not know Chinese, it is evident the poster is putting the image of Mao in line with the rising sun, trying to highlight his importance as the force that gives life to China and its people.
