What does revolution means? Describe it in your own words

Revolution in my words means:

Here is an example of a revolution:

They began a revolution after the neighboring country attacked the other country, and they thought the nation was not doing enough.

To me, revolution means a forcible change that is fought for, like a change in government, but in scientific or astrological terms, it could also mean the movement of a planet around the sun.
