It was through her relations with these wild horsemen of the borderland that Poland became eventually involved in a war with the Ottoman Turks. The yoke of Poland had always sat heavily upon the Cossack tribes. Proud independent and high-spirited by nature, they could not brook the insolence of the Polish nobles, or tamely submit to the rapacity and extortion of their Jewish stewards. In 1648 they boldly rose in rebellion and assisted by the Tartars offered their allegiance to Alexis of Russia. The rising was well-timed, for owing to the ambition of Charles X. of Sweden, John Casimir of Poland soon found his country attacked on all sides by Sweden Brandenburg and Russia, his capital in the hands of his foes, and himself a fugitive in Silesia. When, however, peace was restored on the Baltic by the treaties of Oliva, Copenhagen, and Kardis in 1660, Poland found herself able to cope with her revolted subjects and their protector. Through the consummate generalship and high personal qualities of John Sobieski, who was sprung from one of the oldest and staunchest of Polish noble families, Alexis and his allies were compelled to sue for peace, and accept the compromise concluded at Andrusoff in 1667. Two years later John Casimir abdicated the throne, and the usual intrigues began between the adherents of France and the Empire to secure a favourable election. Election of Michael as king, 1669. But at the moment through the misfortunes of John Casimir, and the unpopularity of Louise de Nevers, his French wife, the Poles would have no one of French blood or French connections, and even John Sobieski who had married a French woman, and belonged to the French interest, was passed over in favour of a national representative, Michael Wiesnowiescki, who had nothing but his good looks and his name to recommend him. The Cossacks regarded the election as an earnest of the recommencement of persecution, for the new king was the son of one of their greatest oppressors. Request for protection by the Cossacks to the Turks, 1671. In 1670 they rushed to arms but were easily defeated by Sobieski. Despairing of all hope of justice from the king they turned to the Turks, and offered to recognise the suzerainty of the Sultan if he would protect them from the tyrant of Poland. Achmet Kiuprili gladly seized the opportunity, and in 1671 declared war against Poland as the champion of her oppressed subjects.

War between Poland and the Turks, 1672–1676.

In June 1672 the preparations were finished and the Sultan himself accompanied by the grand vizier appeared before the almost impregnable fortress of Kaminiec, the key of Podolia. In less than a month it fell, and the craven-hearted king Michael, dismayed at the blow, negotiated a treaty at Buczacz by which he surrendered Podolia and the Ukraine and consented to pay tribute. Stung with indignation at such a disgrace the diet refused to ratify the treaty, and rallied all the forces of the nation under John Sobieski to resist to the uttermost. For four years the heroic struggle continued. Without receiving any help from the great powers, now, through the ambition of Louis XIV., engaged in a deadly conflict on the Rhine and the Scheldt, threatened by intrigues behind his back at court, endangered by insubordination in his camp, John Sobieski, by sheer ascendency of personal character and commanding military talent, managed not only to stem the Turkish advance into Podolia and Galicia, but to inflict on the best of the Turkish generals crushing defeats at Choczim (1673) and Lemberg (1675), and to drive them back in confusion across the Danube. In 1674 in the very midst of the struggle the incapable Michael died, and the Poles hailed with enthusiasm their hero as their king. Yet characteristically enough they did not for that serve him one whit the better. John Sobieski elected King, 1674. Two years later he found himself in the direst straits, with his small army hemmed in by the swarming enemy at Zurawno on the Dniester, unable to break out of the enclosing lines, without any hope of timely relief. But even at this crisis the magic of his name prevailed, and Ibrahim the Turkish general preferred to make peace rather than to run the risk of encounter with the lion in his den. Peace of Zurawno, 1676. The peace of Zurawno, concluded in October 1676, secured to the Sultan the possession of Kaminiec and part of the Ukraine, but it marks by these very concessions the failure of Achmet Kiuprili’s great design of binding upon the brows of his master the laurel wreath of Mohammed II.

Kara Mustafa made grand vizier, 1676.

Seven days after the peace of Zurawno Achmet Kiuprili died, but his policy did not die with him. His successor and brother-in-law, Kara Mustafa, was fired with an equal ambition but was not possessed of equal talent. Haughty luxurious and boastful he soon began to destroy, while seeking to extend, the power which Mohammed and Achmet had so diligently built up. He determined to win his way to the heart of Christendom at a blow by the conquest of Vienna itself. Preparations for an invasion on a scale unexampled and irresistible were secretly set on foot. The old alliance with France was renewed by the grant of fresh trade and diplomatic privileges. Peace was made with Russia and ratified with Poland. By these measures the grand vizier hoped to procure the isolation of the Emperor, and he very nearly succeeded. For some years the Hungarians had been on bad terms with the Emperor. Leopold had pursued a policy both of religious and political repression. With the object of introducing more centralisation into the government, he abolished the office of palatine, and ruled Hungary through Viennese officials. Risings against the Emperor in Hungary, 1674–1681. With the object of rooting out Protestantism he handed over the management of religious affairs to the Jesuits, and banished and sent to the galleys Protestant ministers on the pretext of seditious agitation. Measures so high-handed and unjust brought about the usual result. The Hungarians took advantage of the war with France on the Rhine, rose against their oppressor in 1674 under Tököli, and were joined by Apafy, the prince of Transylvania. In 1681 they found themselves strong enough to force the Emperor to revive the office of palatine and grant religious toleration. But Tököli was not content with this. He desired to become ruler of Hungary himself, and willingly listened to the persuasions of Kara Mustafa to join the Turkish invasion, and accept the government of Hungary as the tributary of the Porte. War between the Emperor and the Turks, 1682. All was now ready. Trusting to Louis XIV. to keep Germany from assisting the Emperor, and to Tököli to raise Hungary against him, Kara Mustafa threw off the mask in 1682, declared Hungary tributary to the Sultan, and crossed the Danube in the spring of 1683 at the head of 150,000 men.

Alliance between Poland and the Emperor, 1683.

He had not reckoned on his allies in vain. Wherever the anxious Emperor turned for help in his extremity, he found himself thwarted by the diplomacy of France. In Germany Louis was completely successful. The diet assembled at Ratisbon separated without granting any aid to its chief. In Poland the struggle was intense, but in the end the indomitable energy and quick tact of John Sobieski prevailed. All grumbling at the selfishness and cowardice of Austria in the days of Poland’s need was chivalrously silenced in the presence of the common danger to Christianity and civilisation. On March 31st an alliance was concluded with the Emperor by which Poland bound herself to place 40,000 men in the field. Meanwhile the Turkish war rolled on. Leopold and the court removed for safety to Passau. The duke of Lorraine, the imperialist general, abandoning Hungary, intrusted the defence of Vienna to count Starhemberg, and posted himself a little lower down the Danube to wait for the Polish reinforcements. On July 9th the Turkish standards appeared before the walls, on the 14th the city was invested and trenches opened.

Siege of Vienna, 1683.

The city was ill prepared for a siege. The garrison only numbered 14,000 men, the town was crowded with peasants from the country, the walls were old and out of repair, while the Turkish engineers and artillery were among the best in Europe. But Mustafa was in no haste to seize the prize. On the 7th of August he drove the imperialists from their fortification on the counterscarp, and the city lay open to the attack from all sides. Yet he hesitated to give the word. He wanted the glory of a capitulation, and the booty of the town for himself. Meanwhile John Sobieski was collecting his forces with all haste at Cracow. Lorraine did not dare to move till he came. As usual money was short, delays were long. It was the 15th August before Sobieski could begin his march, and even then he had to leave the Lithuanians behind. On the 2d of September he was on the Danube at the head of his cavalry. On the 5th he took over the command of the united armies of the Empire and of Poland. On the 6th he crossed the Danube by the bridge at Tuln. On the 11th he reached the height of the Kahlenberg and looked down on the vast camp of the Turks encumbering the plain which stretches between the heights and the spire of St. Stephen’s. He had come not a moment too soon. The Turkish engineers had already undermined the walls, disease had broken out in the crowded city, but when they saw his signal-fires from the mountain the besieged felt that the end of their trials had come and victory was within their grasp. Defeat of the Turks by John Sobieski, 1683. They were not disappointed. On the morning of the 12th, after having received the Holy Communion at the chapel of the Leopoldsberg, John Sobieski ordered the attack. Quickly driving the Turkish advance guard from the vineyards which clothe the sides of the Kahlenberg he found himself opposite the main Turkish battle in the plain about noon. As his Poles charged with the war shout ‘Sobieski for ever’ the Turks were seized with a panic at the sound of the dreaded name and fled on all sides. Sobieski seized the favourable moment with his usual tactical skill, and threw his whole army upon the retreating masses with a tremendous shock before they had time to recover themselves. The battle was won, Vienna was saved, and Christendom preserved. The whole camp of the invader with its streets of tents, its bazaars, its mosques, its luxury, all fell into the hands of the victor. Kara Mustafa himself hardly escaped with his life in the general confusion, and only rallied the remains of his beaten army at Belgrade.

The Holy League, 1684.
