A '''revolution''' refers to any [[social]], economic, or political upheaval and change. Revolutions may be violent ([[French Revolution]]), or peaceful ([[Glorious Revolution]]). Revolutions sometimes consist of independence movements ([[American Revolution]]), and at other times civil wars ([[Russian Revolution]]). [[Karl Marx]], the father of modern [[communism]], believed that revolutions were inevitable and that the underclass would revolt against the ruling class. Marx's ideas never came to fruition however due to the collapse of [[communism]] and a general rise in living conditions throughout the democratic world.<ref>http://www.crf-usa.org/bria/bria19_2a.htm</ref>

In [[astronomy]], a revolution refers to a planetary object completing a full [[orbit]]. Because the word "revolution" comes from the [[Latin]] ''revolutio'', meaning "''turnaround''", it can be seen to make sense in both contexts.
