After WWII, differences between the Western and Eastern animation became heavily divided by political factors.
In the West, particularly in America, animators found it relatively easy to recover. America had not experienced as severe losses that most of Western Europe had experienced. With the rise of Nazi power, many creatives found it in their best interest to flee elsewhere, with a lot of creatives ending up in America. Some of the industries in western Europe had to be rebuilt from the ground up as a result of warfare. Animation in North America flourished because studios were owned by private companies, so animators were free to experiment as they wished. However, there were limits to their freedom; many people were hunted down and made unemployable by the government and their neighbors if they expressed any opinions that could be perceived to be communist or sympathetic to communists.
Any celebrity, intellectuals, and those that chose to disagree with certain politicians’ opinions were marked as Communists. These people were deemed to be unemployable. In America, those that were suspected to be Communists were kept track of by the FBI. In Canada, suspected Communists were investigated and deported. Despite these limitations, animators were able to work on advertising projects that would fund their personal projects.
The USSR and China suffered heavy losses directly before and after WWII. Russia, in particular, had undergone a bloody civil war directly before WWI. They would also experience heavy civilian losses due to famine under Stalin’s rule. China would experience their own civil war shortly after WWII. Combined with the effects of WWII, many civilians would die, leading to severe brain drain. As a result of the brain drain, some countries had to rebuild their animation industries from scratch.
Communist governments would financially sponsor their artists. However, the animators were hampered from telling the stories they wanted to tell by their governments. In the USSR, governments would dictate that all movies made must have a moral. Because it was important to foster nationalism, animators were obliged to explore traditional art styles. They were also obliged to tell traditional stories that were unquestionably nationalistic. The animators were warned against relying too heavily on Western styles.
