Answer: A. It was the home of the emperor and his family.
The Forbidden City was given its name because it was the home of the emperor and his family. Between 1420 and 1644, the forbidden city served as the seat of the Ming dynasty until it was captured by rebel forces in April 1644 in an attack led by Li Zicheng; a self-proclaimed emperor of the Shun dynasty. The Forbidden City served as the political and ceremonial center of the government of china for over 500 years. This UNESCO world heritage site is believed to be a mirror image of the northern star on earth. It is called forbidden because entry into the city is prohibited or else with the consent of the emperor.
