Ok kiddo, let me tell you a story about something that happened a long time ago. In 1917, there was a big change in a country called Russia. The people who lived there didn't like the way their country was being run, so they tried to change it.
At first, there was what we call the February Revolution. This means that in February of 1917, the people decided they didn't want to have a king anymore. Instead, they wanted to have a government that was elected by the people. This made a lot of people happy, but not everyone.
Later that year, in October, there was another revolution. This is called the Bolshevik Revolution. The Bolsheviks were a group of people who wanted to take control of Russia. They were led by a man named Vladimir Lenin. He believed that the workers of Russia should have more power and that they should be able to control the government.
So the Bolsheviks took control of the government and they started to change things. They took away the land from the rich people and gave it to the workers. They also took control of factories and other businesses. This made a lot of people happy because they now had more things for themselves and their families.
But not everyone was happy with the Bolsheviks. Some people thought they were taking away too much power and control from the people. This led to a series of conflicts and fighting called the Russian Civil War.
The war lasted for a few years and it was very difficult for the people of Russia. But eventually, the Bolsheviks won and they established a new government called the Soviet Union. This government was based on the ideas of communism, which means that everyone shares everything equally.
The other countries around Russia were watching all of this happen, and some of them started their own revolutions too. This was a big time of change for a lot of people, and it helped to shape the way the world looks today.
