Jomo Kenyatta is an example of an independence leader during the 20th century.

I believe it was because the government was afraid that they might be spies for Japan, so they thought it was safer to keep them in one place so it would be easier to keep an eye on them. It also stemmed from racism due to the attack on Pearl Harbor and the U.S. fighting against the Japanese in the Pacific.
