When the Eiffel Tower was finished, Gustave Eiffel put the French flag on top of it. The flag has three colors: blue, white, and red. These colors are important because they represent the ideas of the French Revolution.
The French Revolution happened a long time ago in 1789. The people of France were not happy because only a few rich and religious people had power, and the regular people didn't have many rights. Also, the country didn't have much money because of wars and the fancy lives of the rich.
People needed a way to get more money, so they suggested that the rich people should pay taxes. At first, the rich people didn't like this idea. But they said they would think about it if it passed a special group called the Estates-General.
The regular people made a group called the National Assembly to represent them, but the king and the rich people tried to stop them. The regular people got really angry and they attacked a big fortress called the Bastille. This was the start of the revolution, and soon it spread all over France.
The people wrote down their goals for the revolution in something called the "Declaration of the Rights of Man and of the Citizens." It said that everyone should be free and equal from the day they are born. The king and queen tried to run away, but they were caught and punished. People used a machine called a guillotine to cut off their heads.
Other countries nearby were scared that the revolution would spread to their lands, so they started to attack France. But a brave general named Napoleon came and protected France. The people of France fought for their rights for about 10 years. Finally, they made a new set of rules called a Constitution, which said that the regular people were the ones in charge of the country.
