A metropolis is a word that means a very big city, that usually has over 500,000 people living in it. A metropolis often has many smaller towns and cities inside its area. The word is very old and began in Greece.
In the past many large cities were called a metropolis due to their size or importance; such as: Alexandria, Angkor, Antioch, Athens, Babylon, Baghdad, Beirut, Benares, Byblos, Cahokia, Carthage, Constantinople, Corinth, Damascus, Dholavira, Ephesus, Great Zimbabwe, Harappa, Jerusalem, Kangla, Leptis Magna, Nanjing, Nineveh, Macchu Picchu, Mohenjo-Daro, Rome, Sarai, Side, Siracuse, Tenochtitlan, Teotihuacan, Tikal, Tyre, Xian and Ur.
The modern metropolises are increasing day by day in this world since pre-21st century.
