The Patriarch of Moscow, whose residence is the Danilov Monastery, serves as the head of the Russian Orthodox Church.
Moscow also remains a major economic center and is home to a large number of billionaires and is perennially considered one of the most expensive cities in the world.
The 17th century was rich in popular risings, such as the liberation of Moscow from the Polish invaders (1612), the Salt Riot (1648), the Copper Riot (1662), and the Moscow Uprising of 1682.
