Fascism is a political ideology that emphasizes the need for a strong, central government and national unity. Fascists believe that a nation is strongest when its people are united under a single, strong leader. They advocate for strict controls on society and the economy, and often use violence and intimidation to achieve their goals. Fascism typically includes elements of nationalism, racism, and anti-communism. Fascism rose to prominence in Europe in the early 20th century, and was a major force in World War II.
