Slavs began in the second half of the ninth century. About the middle of the tenth, Mechislav (Mieczislaw), the ruler, received Christianity, and the modest title of Count of the German Empire. Boleslav the Brave, his son and successor, extended his territory to the upper Elbe, from which region its boundary line passed through or near Berlin, whence it followed the Oder to the sea. Before his death, in 1025, Boleslav wished to be anointed king by the Pope. The ceremony was denied him, therefore he had it performed by bishops at home. About a century later the western boundary was pushed forward by Boleslav Wry-mouth (1132–1139) to a point on the Baltic about half-way between Stettin and Lubeck. This was the greatest extension of Poland to the west. Between this line and the Elbe were Slav tribes; but the region had already become marken (marches) where the intrusive Germans were struggling for the lands and persons of the Slavs.
The eastern boundary of Poland at this period served also as the western boundary of Russia from the head-waters of the western branch of the river San in the Carpathian Mountains at a point west of Premysl (in the Galicia of to-day) to Brest-Litovsk, from which point the Russian boundary continued toward the northeast till it reached the sea, leaving Pskoff considerably and Yurieff (now Dorpat) slightly to the east,--that is, on Russian territory. Between Russia, north of Brest-Litovsk and Poland, was the irregular triangle composing the lands of Lithuanian and Finnish tribes. From the upper San the Russian boundary southward coincided with the Carpathians, including the territory between the Pruth to its mouth and the Carpathians. This boundary between Poland and Russia, established at that period, corresponds as nearly as possible with the line of demarcation between the two peoples at the present day.
During the two centuries following 1139, Poland continued to lose on the west and the north, and that process was fairly begun through which the Germans finally excluded the Poles from the sea, and turned the cradle of Poland into South Prussia, the name which it bears to-day.
At the end of the fourteenth century a step was taken by the Poles through which it was hoped to win in other places far more than had been lost on the west. Poland turned now to the east; but by leaving her historical basis on the Baltic, by deserting her political birthplace, the only ground where she had a genuine mission, Poland entered upon a career which was certain to end in destruction, unless she could win the Russian power by agreement, or bend it by conquest, and then strengthened by this power, turn back and redeem the lost lands of Pomerania and Prussia.
The first step in the new career was an alliance with Yagello (Yahailo) of Lithuania, from which much was hoped. This event begins a new era in Polish history; to this event we must now give attention, for it was the first in a long series which ended in the great outburst described in this book,--the revolt of the Russians against the Commonwealth.
To reach the motives of this famous agreement between the Lithuanian prince and the nobles and clergy of Poland,--for these two estates had become the only power in the land,--we must turn to Russia.
Lithuania of itself was small, and a prince of that country, if it stood alone, would have received scant attention from Poland; but the Lithuanian Grand Prince was ruler over all the lands of western Russia as well as those of his own people.
What was Russia?
The definite appearance of Russia in history dates from 862, when Rurik came to Novgorod, invited by the people to rule over them. Oleg, the successor of this prince, transferred his capital from Novgorod to Kieff on the Dnieper, which remained the chief city and capital for two centuries and a half. Rurik's great-grandson, Vladimir, introduced Christianity into Russia at the end of the tenth century. During his long reign and that of his son Yaroslav the Lawgiver, the boundary was fixed between Russia and Poland through the places described above, and coincided very nearly with the watershed dividing the two river-systems of the Dnieper and the Vistula, and serves to this day as the boundary between the Russian and Polish languages and the Eastern and Catholic churches.
In 1157 Kieff ceased to be the seat of the Grand Prince, the capital of Russia. A new centre of activity and government was founded in the north,--first at Suzdal, and then at Vladimir, to be transferred later to Moscow.
In 1240 the conquest of Russia by the Tartars was complete. Half a million or more of armed Asiatics had swept over the land, destroying everything where they went. A part of this multitude advanced through Poland, and were stopped in Silesia and Moravia only by the combined efforts of central Europe. The Tartar dominion lasted about two hundred and fifty years (1240–1490), and during this period great changes took place. Russia before the Tartar conquest was a large country, whose western boundary was the eastern boundary of Poland; liberated Russia was a comparatively small country, with its capital at Moscow, and having interposed between it and Poland a large state extending from the Baltic to the Black Sea,--a state which was composed of two thirds of that Russia which was ruled before the Tartar conquest by the descendants of Rurik; a state which included Little, Red, Black, and White Russia, more than two thirds of the best lands, and Kieff, with the majority of the historic towns of pre-Tartar Russia.
How was this state founded?
This state was the Lithuanian Russian,--Litva í Rus (Lithuania and Russia), as it is called by the Russians,--and it rose in the following manner. In the irregular triangle on the Baltic, between Russia and Poland of the twelfth century, lived tribes of Finnish and Lithuanian stock, about a dozen in number. In the thirteenth and fourteenth centuries these were all conquered,--the Prussian Lithuanians from the Niemen to the Vistula, by the Teutonic Knights, aided by crusading adventurers from western Europe; the others, Lithuanian and Finnish, by the Knights of the Sword,--with the exception of two tribes, the Lithuanians proper, on the upper waters of the Niemen and its tributaries, and the Jmuds or Samogitians on the right bank of the same river, lower down and between the Lithuanians and the sea. These two small tribes were destined through their princes--remarkable men in the fullest sense of the word--to play a great part in Russian and Polish history. It is needless to say much of the Lithuanians, who are better known to scholars than any people, perhaps, of similar numbers in Europe. The main interest in them at present is confined to their language, which, though very valuable to the philologist and beautiful in itself, has never been used in government or law, and has but one book considered as belonging to literature,--"The Four Seasons" by Donaleitis.
Though small, the Lithuanian country, ruled by a number of petty princes, was as much given to anarchy as larger aggregations of men. United for a time under Mindog by reason of pressure from outside, the Lithuanians rose first to prominence under Gedimin (1315–1340), who in a quarter of a century was able to substitute himself for the petty princes of western Russia and extend his power to the south of Kieff. Gedimin was followed by Olgerd, who with his uncle Keistut ruled till 1377; during which time the domains of the Lithuanian prince were extended to the Crimea, and included the whole basin of the Dnieper with its tributaries, together with the upper Dvina. Gedimin and Olgerd respected in all places the clergy of the Eastern Church, and thus acquired rule over a great extent of country with comparative ease and rapidity.
Olgerd, who had completed a great state, left it to his sons and his brother Keistut. Yagello (Yahailo), one of these sons, had Keistut put to death; his brothers and cousins fled; Yagello became sole master. At this juncture the nobles and clergy of Poland effected an arrangement by which Yagello, on condition of becoming a Catholic, introducing the Catholic religion into Lithuania, and joining the state to Poland, was to marry the Queen Yadviga (the last survivor of the royal house) and be crowned king of Poland at Cracow. All these conditions were carried out, and with the reign of Yagello Polish history assumes an entirely new character.
With the establishment by Gedimin and Olgerd of the Lithuanian dynasty and its conquests, there were two Russias instead of one,--Western Russia, ruled by the house of Gedimin, and Eastern Russia, ruled by the house of Rurik. It had become the ambition of the Lithuanian princes to unite all Russia; it had long been the fixed purpose of the princes at Moscow to recover their ancient patrimony, the lands of Vladimir and Yaroslav;
