A majority of the Taborites elected a priest, called Procopius the Great, as their commander in Ziska's stead; the others, who thenceforth styled themselves "Orphans," united under another priest, Procopius the Little. The approach of another Imperial army, in 1426, compelled them to forget their differences, and the result was a splendid victory over their enemies. Procopius the Great then invaded Austria and Silesia, which he laid waste without mercy. The Pope called a _fourth_ Crusade, which met the same fate as the former ones: the united armies of the Archbishop of Treves, the Elector Frederick of Brandenburg and the Duke of Saxony, 200,000 strong, were utterly defeated, and fled in disorder, leaving an enormous quantity of stores and munitions of war in the hands of the Bohemians. Procopius, who was almost the equal of Ziska as a military leader, made several unsuccessful attempts to unite the Hussites in one religious body. In order to prevent their dissensions from becoming dangerous to the common cause, he kept the soldiers of all sects under his command, and undertook fierce invasions into Bavaria, Saxony and Brandenburg, which made the Hussite name a terror to all Germany. During these expeditions one hundred towns were destroyed, more than fifteen hundred villages burned, tens of thousands of the inhabitants slain, and such quantities of plunder collected that it was impossible to transport the whole of it to Bohemia. Frederick of Brandenburg and several other princes were compelled to pay heavy tributes to the Hussites: the Empire was thoroughly humiliated, the people weary of slaughter, yet the Pope refused even to call a Council for the discussion of the difficulty. As for the Emperor Sigismund, he had grown tired of the quarrel, long before. Leaving the other German States to fight Bohemia, he withdrew to Hungary and for some years found enough to do in repelling the inroads of the Turks. It was not until the beginning of the year 1431, when there was peace along the Danube, that he took any measures for putting an end to the Hussite war. Pope Martin V. was dead, and his successor, Eugene IV., reluctantly consented to call a Council to meet at Basel. First, however, he insisted on a _fifth_ Crusade, which was proclaimed for the complete extermination of the Hussites. The German princes made a last and desperate effort: an army of 130,000 men, 40,000 of whom were cavalry, was brought together, under the command of Frederick of Brandenburg, while Albert of Austria was to support it by invading Bohemia from the south.
