At the first division of Poland, Royal Prussia of The Deluge, the territory lying between the Vistula and Brandenburg, went to the new kingdom; and Brandenburg, Pomerania, and Prussia became continuous territory.
The early success of the Teutonic Knights was so great that in the third half century of their rule on the Baltic their power overshadowed Poland, which was thus seriously threatened. Toward the end of the fourteenth century, however (1386), the Poles escaped imminent danger by their union with Lithuania and Russia. Through this most important connection they rose at once from a position of peril to one of safety and power.
This union, brought about through the marriage of the Polish princess Yadviga to Yagyello, Grand Prince of Lithuania, and by exceedingly adroit management on the part of the Polish nobles and clergy, opened to the Poles immense regions of country and the way to vast wealth. Before the union their whole land was composed of Great and Little Poland, with Mazovia (see map); after the union two thirds of the best lands of pre-Tartar Russia formed part of the Commonwealth.
Since Poland managed to place and maintain itself at the head of affairs, though this roused at all times opposition of varying violence in the other two parts of the Commonwealth, the social ideals and political structure of Poland prevailed in Lithuania and Russia, so far as the upper classes were concerned. In Lithuania, by the terms of the union, all were obliged to become Catholic; in different parts of Russia, which was Orthodox, the people were undisturbed in their religion at first; but after a time the majority of the nobles became Catholic in religion, and Poles in language, name, manners, and ideas. To these was added a large immigration of Polish nobles seeking advancement and wealth. All Russia found itself after a time under control of an upper class which was out of all sympathy with the great mass and majority of the people.
During the Yagyellon dynasty, which lasted from 1386 to 1572, the religious question was not so prominent for any save nobles; but ownership of their own land and their own labor was gradually slipping away from the people. During the reign of Sigismund III. (1587-1632), religion was pushed to the foreground, the United Church was brought into Russia; and land and religion, which raise the two greatest problems in a State, the material and the spiritual, were the main objects of thought throughout Russia.
Under Vladislav in 1648 the storm burst forth in Southern Russia. There was a popular uprising, the most wide-spread and stubborn in history, during which the Poles lost many battles and gained one great victory, that of Berestechko; the Southern Russians turned to the North, and selected the Tsar Alexai Mihailovich as sovereign.
Jan. 8, 1654, there was a great meeting in Pereyaslav,[[2]] at which Bogdan Hmelnitski, hetman of the Zaporojian army and head of all Southern Russia, after he had consulted with the Cossacks, took his place in the centre of the circle, and in presence of the army, the people, and Buturlin, the envoy of Alexai Mihailovich, said:—
“Gentlemen, Colonels, Essauls, Commanders of hundreds, the whole Zaporojian army, and all Orthodox Christians,—You know how the Lord delivered us from the hands of our enemies who persecuted the Church of God and were envenomed against all Christians of our Eastern Orthodoxy. We have lived six years without a sovereign, in endless battles against our persecutors and enemies who desire to root out the church of God, so that the Russian name may not be heard in our land. This position has grown unendurable, and we cannot live longer without a sovereign. Therefore we have assembled a council before the whole people, so that you with us may choose from four sovereigns that one whom you wish. The first is the Sovereign of Turkey, who has invited us under his authority many times through his envoys; the second is the Khan of the Crimea; the third the King of Poland, who, if we wish, may receive us into former favor; the fourth is the Orthodox sovereign, the Tsar and Grand Prince Alexai Mihailovich, the sole ruler of all Russia, whom we have been imploring six years with unceasing petitions. Choose whom you like. The Sovereign of Turkey is a Mussulman; you all know how our brethren, the Greeks, Orthodox Christians, suffer, and what persecution they endure from godless men. A Mussulman also is the Khan of the Crimea, whom we took into friendship of necessity, by reason of the unendurable woes which we passed through. Of persecutions from Polish lords it is needless to speak; you know yourselves that they esteemed a Jew and a dog more than a Christian, our brother. But the great Orthodox sovereign of the East is of one faith with us, one confession of the Greek rite; we are one spiritual body with the Orthodoxy of Great Russia, having Jesus Christ for our head. This great sovereign, this Christian Tsar, taking pity on the suffering of our Orthodox church in Little Russia, giving ear to our six years’ entreating, has inclined his heart to us graciously, and was pleased to send with his favor dignitaries from near his person. If we love him earnestly, we shall not find a better refuge than his lofty hand. If any man is not agreed with us, let him go whither he pleases; the road is free—”
Here the whole people shouted: “We choose to be under the Orthodox sovereign; better to die in our Orthodox faith than to go to a hater of Christ, to a Pagan!”
Then the Pereyaslav colonel, Teterya, passed around in the circle, and asked in every direction: “Are all thus agreed?”
