Moscow is situated on the Moskva River in the Central Federal District of European Russia, making it Europe's most populated inland city.
It is home to the Ostankino Tower, the tallest free standing structure in Europe; the Federation Tower, the tallest skyscraper in Europe; and the Moscow International Business Center.
By its territorial expansion on July 1, 2012 southwest into the Moscow Oblast, the area of the capital more than doubled, going from 1,091 to 2,511 square kilometers (421 to 970 sq mi), and it gained an additional population of 233,000 people.
Ivan I eventually defeated Tver to become the sole collector of taxes for the Mongol rulers, making Moscow the capital of Vladimir-Suzdal.
By paying high tribute, Ivan won an important concession from the Khan.
Daniel was still a child at the time, and the big fort was governed by tiuns (deputies), appointed by Daniel's paternal uncle, Yaroslav of Tver.
