Ivan’s troops, which did not share the timidity of their high commander, next reduced Bulgaria, and the death of his brothers enabled Ivan to add still further, and with less title, to his dominions. His brother Andrew was, in 1493, accused of the usual perfidy and corresponding with the Polish-Lithuanian kingdom. He was thrown into prison, and there he conveniently died. Ivan summoned his bishops and monks and, as the tears trickled down his gaunt face and grey beard, confessed that he had sinned in sanctioning the cruel treatment of his brother. But he added Andrew’s territory, and that of two other brothers, to his large dominion. In the following year the lover of peace attacked the joint kingdom of Lithuania and Poland, which had so long afflicted Russia. Ivan had married his daughter to the Polish king, and had strictly stipulated that she should have entire freedom to practise the true religion amongst the adherents of the Pope. In 1494 Ivan found that this agreement was grossly disregarded, and his beloved daughter ran some peril of her soul. Later Russian historians have learned from the daughter’s letters that she had no complaint except against the interested intrigues of Ivan himself. However, a holy war was proclaimed, and a good deal of western Russia was wrested from the Poles and added to the Moscovite dominion. Such were the methods by which Ivan III doubled the patrimony of his fathers, and accumulated the wealth and power by which his more famous grandson would create the great Russia of the Romanoffs. It remains to see how Ivan organised his dominion, strengthened the autocracy, and raised the culture and splendour of his capital. Ivan was by nature autocratic. He did not make counsellors of his boyars, as had been the custom, and they were compelled to learn the art of silence in presence of their master. But it was Ivan’s wife who directed this disposition and created a Court in harmony with it. The Turks had taken Constantinople and had driven the remnants of half a dozen rival Greek royal families, and all that remained of Greek culture, into Italy. Amongst the fugitives was the clever and ambitious niece of the last emperor, Sophia Palæologus. The Pope, who saw in this heavy chastisement of the Greek schism a ray of hope of the reunion of Christendom, fathered the homeless princess and sought for her a useful marriage. Ivan accepted her and the Papal dowry. They were married early in his reign (in 1472), and her forceful ambition was behind many of the schemes of conquest we have reviewed. It was especially she and the clergy who forced upon the prince his inglorious campaign against the Tatars.
