It is worthy of mention that it was on the basis of tribute that the relations between Turkey and Rumania rested until 1877, the Rumanian provinces becoming at no time what Hungary was for a century and a half, namely, a Turkish province. In a battle arising following his frustration—by means not unconnected with his name—of a Turkish plot against his person, Vlad the Impaler (1458-62) completely defeated the Turks under Mohammed II; but an unfortunate feud against Stephen the Great, Prince of Moldavia, put an end to the reign of Vlad—a fierce but just prince. A period of the most lamentable decadence followed, during which Turkish domination prevailed more and more in the country. During an interval of twenty-five years (1521-46) no less than eleven princes succeeded one another on the throne of Muntenia, whilst of the nineteen princes who ruled during the last three-quarters of the sixteenth century, only two died a natural death while still reigning. In Moldavia also internal struggles were weakening the country. Not powerful enough to do away with one another, the various aspirants to the throne contented themselves with occupying and ruling over parts of the province. Between 1443-7 there were no less than three princes reigning simultaneously, whilst one of them, Peter III, lost and regained the throne three times. For forty-seven years (1457-1504) Stephen the Great fought for the independence of Moldavia. At Racova, in 1475, he annihilated an Ottoman army in a victory considered the greatest ever secured by the Cross against Islam. The Shah of Persia, Uzun Hasan, who was also fighting the Turks, offered him an alliance, urging him at the same time to induce all the Christian princes to unite with the Persians against the common foe. These princes, as well as Pope Sixtus IV, gave him great praise; but when Stephen asked from them assistance in men and money, not only did he receive none, but Vladislav, King of Hungary, conspired with his brother Albert, King of Poland, to conquer and divide Moldavia between them. A Polish army entered the country, but was utterly destroyed by Stephen in the forest of Kosmin. Having had the opportunity of judging at its right value the friendship of the Christian princes, on his death-bed Stephen advised his son Bogdan to make voluntary submission to the Turks. Thus Moldavia, like Wallachia, came under Turkish suzerainty.
