To cite but a few cases. Shortly after the death of Khmelnitsky, his secretary, Ivan Vyhovsky, almost unified the Host as a new hetman succeeding the weak Yury Khmelnitsky. Vyhovsky and his friends realized that with a weakened Poland, it might be possible for the Kozaks to force upon the King a recognition of their rights. He drew up the Union of Hadiach in 1658 and this more than fulfilled the dreams of Khmelnitsky, for it made the Kozak Host and Rus’ a third member of the Polish state along with Poland and Lithuania. It again gave the Orthodox Metropolitan the right to sit in the Polish Senate and conferred upon the Academy of Kiev the same rights that were given to the Polish Universities of Krakow and Wilno. It was all in vain. The blind hate of the Polish clergy and aristocratic landowners and Muscovite intrigues destroyed the plans of Vyhovsky and the Poles speedily withdrew their promises. Ten years later Peter Doroshenko, more hostile to the Poles, manipulated his power so skilfully that he was able to win complete independence from Poland and became the master of the right bank. Through an alliance with Mnohohrishny, the hetman of the left bank, he bade fair to unite again the whole of Ukraine with the hope of securing a definite autonomy from the Tsar. It was of no use. The officers overthrew Mnohohrishny because he was the son of a peasant and then they appealed to Moscow against Doroshenko. Of course the Tsar heard them for he welcomed the opportunity to deprive the Host of its rights to deal with foreign policy, and executed Mnohohrishny. Doroshenko tried in vain to secure Turkish help but this was not forthcoming and the hatred of the Kozaks for Islam brought about his downfall. When he had to surrender to Moscow, he received a long term in Siberia. Then came the turn of Ivan Samoylovich, who was as sympathetic and obedient to Moscow as the others had been critical and independent. He won a certain amount for the Host at the price of taking part in Muscovite plans against Turkey. Yet when an expedition under Prince Golitsyn met with failure against the Crimea, because of disregard of his advice, the other officers accused him to the Tsar of betraying the Russians. Samoylovich was deposed and imprisoned and his son was executed. Thus while the Host was relapsing into discord, it gave both Tsar and King the power to do with the Ukrainian lands as they would. In 1667, by the Treaty of Andrusivo, the two divided Ukraine at the Dnyeper, with Poland holding the right bank and Moscow the left and the city of Kiev on the right bank. This last was nominally for two years, but Moscow never returned the prize and used the occupation for still greater demands.
