Washington, D.C., formally the District of Columbia and also known as D.C. or Washington, is the capital city of the United States of America. Founded after the American Revolution, Washington was named for George Washington, the first president of the United States and a Founding Father. As the seat of the United States federal government and several international organizations, Washington is an important world political capital. Located on the Potomac River bordering Maryland and Virginia, the city is one of the most visited cities in the United States, with more than 20 million visitors annually.The signing of the Residence Act on July 16, 1790, approved the creation of a capital district located along the Potomac River near the country's East Coast. The U.S. Constitution provided for a federal district under the exclusive jurisdiction of the U.S. Congress, and the district is therefore not a part of any U.S. state. The states of Maryland and Virginia each donated land to form the federal district, which included the pre-existing settlements of Georgetown and Alexandria. The City of Washington was founded in 1791 to serve as the new national capital. In 1846, Congress returned the land originally ceded by Virginia, including the city of Alexandria; in 1871, it created a single municipal government for the remaining portion of the district.
Washington had an estimated population of 705,749 as of July 2019, making it the 20th most populous city in the United States. Commuters from the surrounding Maryland and Virginia suburbs raise the city's daytime population to more than one million during the workweek.

Palermo ( pə-LAIR-moh, -LUR-, Italian: [paˈlɛrmo] (listen); Sicilian: Palermu, locally [paˈlɛmmʊ]; Latin: Panormus, from Greek: Πάνορμος, romanized: Pánormos) is a city of southern Italy, the capital of both the autonomous region of Sicily and the Metropolitan City of Palermo. The city is noted for its history, culture, architecture and gastronomy, playing an important role throughout much of its existence; it is over 2,700 years old. Palermo is in the northwest of the island of Sicily, by the Gulf of Palermo in the Tyrrhenian Sea.
The city was founded in 734 BC by the Phoenicians as Ziz. Palermo then became a possession of Carthage. Two Greek colonies were established, known collectively as Panormos or "All-Port"; the Carthaginians used this name on their coins after the 5th century BC. As Panormus, the town became part of the Roman Republic and Empire for over a thousand years. From 831 to 1072 the city was under Arab rule during the Emirate of Sicily when the city first became a capital. The Arabs shifted the Greek name into Balarm (Arabic: بَلَرْم), the root for Palermo's present-day name. Following the Norman reconquest, Palermo became the capital of a new kingdom (from 1130 to 1816), the Kingdom of Sicily and the capital of the Holy Roman Empire under Emperor Frederick II and King Conrad IV.
The population of Palermo urban area is estimated by Eurostat to be 855,285, while its metropolitan area is the fifth most populated in Italy with around 1.2 million people. In the central area, the city has a population of around 676,000 people.
