Meanwhile, Novgorod was going its own way. Its far northwestern forest location deterred the Mongols from attacking it. Its prince, Alexander (r. 1236–63), negotiated skilfully with them, and in return for paying an ample tribute received a special charter guaranteeing the city’s right to govern itself. He had good reason to mollify the Mongols, for his western frontier was threatened by the Swedes; he defeated them in 1240 in a battle on the River Neva – hence his nickname Nevskii. In addition, the Teutonic Knights were trying to block Novgorod’s lucrative trading routes in the Baltic. When they advanced towards the city itself in 1242, Alexander overcame them in battle on the frozen Lake Peipus. The scale of the battle may have been exaggerated by later chroniclers, but its significance cannot be. It established the River Narva and Lake Peipus as a permanent boundary between Eastern and Western Christianity.
Alexander’s younger son, Daniil, became ruler of the new principality of Moscow. During the early 14th century, he and his successors succeeded in establishing themselves as the favoured recipients of the
The recovery of Rus took place not only in the north and east. The south-western principalities, notably Galicia and Volynia, allied themselves with Lithuania, which defeated the Golden Horde at the Battle of Blue Waters in 1362, and was able to establish its authority over Kiev and most of the original heartland of Rus. From the late 14th century, Lithuania, for its own protection, sought union with Poland, to form what at the time was the largest kingdom in Europe. The Lithuanian princes accepted the Catholic religion, though many of their people remained Orthodox. In this way, the western and south-western principalities of Kievan Rus adopted an elite Latinate Polish culture, which distinguished them from those of the north and east. The language spoken in the west, initially known as Rusin (Ruthenian), evolved into modern Belorussian and Ukrainian. Eventually, their territories became contemporary Belorussia and a large part of Ukraine.
Since the Metropolitanate was the most important ‘all-Rus’ institution, its location and powers were vital to the development of Kievan Rus’s successor states. Kiev itself lost its ascendancy because it was especially vulnerable to steppe raids. In 1325, the Metropolitanate relocated to Moscow; Metropolitan Petr, who made the move, was subsequently canonized with the support of Ivan Kalita, and his tomb became a pilgrimage site. This was a crucial moment: from then on, Moscow became the centre of Russian Orthodox Christianity, though at times contested by Kievan Metropolitans with Lithuanian backing.
During the 14th and 15th centuries, monasteries multiplied and acquired extensive new lands in the northern and eastern forests. Their motive was both spiritual and economic. When young monks became discontented with the discipline in their home foundations, they would break away to set up their own
