To make long things short: Russia stays disunited, although some centers of power are established: Novgorod reigns in the North and slowly starts to expand East; Vladimir-Suzdal controls the thrones of the East, Chernigov those of South-East. The western principalities are weaker, threatened by the Teutonic Order, the freshly united Poland, and the strong Hungary. And Kiev suffers since the trade with Byzantium is cut off until 1276. There are many little wars for control of the thrones, deposings of princes and coups - too many to mention. 1274: Hungary occupies Serbia.
