The city covers an area of 2,511 square kilometres (970 sq mi), while the urban area covers 5,891 square kilometres (2,275 sq mi), and the metropolitan area covers over 26,000 square kilometres (10,000 sq mi).

Originally established in 1147, Moscow grew to become a prosperous and powerful city that served as the capital of the Grand Duchy that bears its namesake. When the Grand Duchy of Moscow evolved into the Tsardom of Russia, Moscow still remained as the political and economic center for most of the Tsardom's history. When the Tsardom was reformed into the Russian Empire, the capital was moved from Moscow to Saint Petersburg, diminishing the influence of the city. The capital was then moved back to Moscow following the Russian Revolution and the city was brought back as the political centre of the Russian SFSR and the Soviet Union. In the aftermath of the dissolution of the Soviet Union, Moscow remained as the capital city of the contemporary and newly established Russian Federation.

As the northernmost and coldest megacity in the world, and with a history that dates over eight centuries, Moscow is governed as a federal city that serves as the political, economic, cultural, and scientific centre of Russia and Eastern Europe. As an alpha world city, Moscow has one of the world's largest urban economies, and is one of the most expensive cities in the world. The city is one of the fastest growing tourist destinations in the world, and is one of Europe's most visited cities.
