DMITRI DONSKOI.
Crafty and unscrupulous, the grand dukes of Moscow were feared by their neighbors. Ivan Kalita, as farmer of the poll-tax, grew immensely wealthy. He collected a double tax from Novgorod, which the republic, although allied with Lithuania, dared not refuse. He bought several towns, besides land in the neighborhood of Vladimir, Rostof, and Kostroma. His title was still Grand Duke of Vladimir, but Moscow was the real capital. Ivan took very good care to stand well with the Church. He built convents and churches, and never went out without an alms-bag or kalita to give money to the poor; hence his surname. The seat of the Metropolitan was still at Vladimir, but he often came to Moscow, and finally moved there; so that it became also the capital of the Church. It is reported that the Metropolitan said to Ivan, "God will bless you and raise you above all other dukes, and this city above all other cities. Your house will reign in this place during many centuries; their hands will conquer all their enemies; the saints will make their dwelling here, and here my bones shall rest."
When Ivan with the Alms-bag died in 1341, he left the bulk of his possessions to his eldest son Simeon, and gave only small estates to his other children; he also forbade that Moscow's territory should be divided. His body was scarcely in the grave before the dukes of Tver and Souzdal were on the way to Saraï to claim the grand dukedom of Vladimir; they were supported by other dukes who disliked and dreaded the Muscovite family. Simeon hurried after them, well provided with some of his father's treasure. He used it so well, that he received the iarlikh, and was installed at Vladimir. Servile toward the khan, he was overbearing toward the other Russian dukes, which procured for him the surname of the Proud. He was the first to assume the title of Grand Duke of all the Russias; and, acting in that capacity, he graciously confirmed the charter of Novgorod, for which he demanded and obtained payment. Simeon died in 1353 of the "black death," a pestilence which was imported from Asia.
Great changes were taking place at Saraï, in the Khan of the Golden Horde. Its power was broken by internal discord, when Mourout, the legal heir of Bati, was attacked by a rival Mamaï, who succeeded in establishing himself at Saraï. Simeon was succeeded by his brother, Ivan II, an easy-going, good-natured man whose reign of six years did not increase the influence of Moscow. At his death, in 1359, he left several minor children, the oldest of whom was Dmitri, a boy of twelve. Dmitri of Souzdal went to Saraï—and secured the iarlikh, which made him Grand Duke of Vladimir, but Alexis, the Metropolitan, was loyal to Ivan's children, and appealed to the khan in the name of his young ward. Mourout, the heir of Bati, declared in his favor, and young Dmitri was taken to Vladimir escorted by an army, and installed. (1363.)
Dmitri Donskoï
The appointment was disputed by the dukes of Tver, Souzdal, and Riazan. Dmitri of Souzdal held an iarlikh from Mourout's opponent, and tried to enter in Vladimir, but was expelled. The Metropolitan excommunicated the opponents of Ivan's son, who held the fort as Grand Duke. Young Dmitri made war upon the Duke of Tver, and after a seven years' struggle (1368-1375), compelled him to renounce his claims.
Dmitri was summoned before the Khan, in 1371. He went but what he saw at Saraï convinced him that the Tartars were no longer able to uphold their authority. He did not hesitate to engage in a struggle with Riazan, although it was supported by a Tartar army. Thereafter, when orders arrived from the khan, Dmitri ignored them. In 1376, he sent a large army to Kazan on the Volga, and forced two Mongol chiefs to pay tribute. Two years later, in 1378, a battle was fought between Dmitri and one of Mamaï's generals in Riazan, when the Tartars were defeated, which made the grand duke exclaim: "Their time is come, and God is with us!" The khan sent an army to ravage Riazan, and made preparations to reëstablish his authority at Moscow.
To make sure of success, Mamaï took two years to collect an immense army and to mature his plans. This could not remain secret to the Russians, who, aroused by Dmitri, laid aside their private feuds to make common cause against the infidels. A large number of dukes assembled at Moscow, and even the Lithuanians promised to send troops to Kostroma where the Russian army was gathering. The Metropolitan assured Dmitri of the victory, and sent two monks to go with the troops. Making the sign of the Cross on their cowls, he said, "Behold a weapon which faileth never!"
