THE FORMATION OF THE PRINCIPALITIES OF NORTHEASTERN RUS' IN THE POST-MONGOL PERIOD (TO THE END OF THE 13TH CENTURY)

The main stages in the territorial formation of the principalities of Northeastern Rus' in the second half of the 13th century are examined. The influence upon this process of the Tatar-Mongol invasion, and the creation of the conditions for the rise of Moscow, Tver', Kostroma, and Gorodets as possible future centers for the unification of the Russian lands, are demonstrated.
