Answer:
Between 1920 and until the early 1940s, the only communist country was the Soviet Union, where the first communist revolution, led by Vladimir Lenin, was successful in 1917.
From the early 1940s onward, communism began to expand rapidly to many areas in the world. For example, after the end of World War II, the Soviet Union expanded communism in Eastern European Countries like Poland, Hungary, and Romania, where it installed puppet governments.
In 1949, another important country became comunist: China. Led by Mao Zedong, the Chinese communists won the civil war against the Chinese nationalists (the Kuomintang, who later fled to Taiwan). In the same year, the Chinese People's Republic was proclaimed.

On August 6 and 9, 1945, the United States dropped two atomic bombs on Hiroshima and Nagasaki, Japan. The two bombings killed between 129,000 and 226,000 people, mostly civilians, and remains the only use of nuclear weapons in an armed conflict.
Is there still radiation in Hiroshima and Nagasaki? Radiation levels in Hiroshima and Nagasaki today are consistent with the very low background levels (natural radioactivity) found anywhere on Earth. There is no effect on the human body.
The plutonium bomb detonated at Nagasaki was actually more powerful than the one used at Hiroshima. Much of the reason for the higher casualty numbers in the latter city is due to the different physical characteristics of the two cities.
