Meanwhile Bebek, the representative of Queen Isabella, was using every means in his power to thwart the efforts of Busbecq and his colleagues. The latter returned home in August, 1557. Verantius was rewarded with the bishopric of Erlau. As far back as June, 1555, allusions to the prospect of his appointment may be found, and the see had been kept vacant for him for more than a year before his actual translation in November, 1557. His office was no sinecure. He was perpetually occupied in providing for the defence of his diocese, in writing to the Pasha of Buda to remonstrate against the continual invasions of the neighbouring Sanjak-beys, and in counterworking the intrigues of Zapolya’s party. His remaining time and energies were devoted to attempts to check the spread of Lutheranism in his diocese. It may be remarked here that John Sigismund was much assisted by his patronage of Lutheranism. His court was the refuge of many Lutheran, and even of Socinian, teachers. An anecdote Verantius gives in one of his letters will show what a hold Lutheranism had obtained in parts of Hungary. When a fire, supposed to be the work of an incendiary, broke out in the monastery of Jaszbereny, most of the inhabitants of the town refused to help to extinguish it, declaring that they would rather the Turks had the monastery than the monks. Zay, the other ambassador, was appointed Governor of Kaschau.[290]
In 1558 the fortress of Tata, near Komorn, eight miles from the right bank of the Danube, was surprised by Hamza, Sanjak-bey of Stuhlweissenburg.
Throughout the negotiations the Sultan insisted on the cession of Szigeth, but was induced in the winter of 1557 to grant a fresh armistice for seven months. In 1559 Ferdinand sent by Albert de Wyss[291] four projects for a treaty, the first of which demanded the restoration of Tata and Fülek, but the last omitted these conditions. The last was presented by Busbecq in the camp at Scutari to Solyman, but was not accepted by him; and the Sultan, on his return to Constantinople, placed Busbecq in a sort of confinement in his house.
In the beginning of 1559 the health of Queen Isabella began to fail, and Melchior Balassa, a great Transylvanian noble, wrote to Ferdinand proposing, on her death, to place Transylvania in his hands. This letter was intercepted, and sent to Isabella, who, having such a proof of the treachery of one of her most trusted adherents, thought it advisable to open negotiations with Ferdinand herself, and, with the Sultan’s approval, did so through her brother the King of Poland. It was proposed that one of Ferdinand’s daughters should marry John Sigismund, and that the latter should have Transylvania and Lower Hungary (the north-eastern part of Hungary, between Poland and Transylvania), but should abandon the title of King. These negotiations were broken off by her death, which took place at Karlsburg in September, and an attempt in the following year to renew them also came to nothing, as John Sigismund refused to renounce the title of King.
In the winter of 1561 Andrew Bathory persuaded his brother Nicholas and Melchior Balassa to go over to Ferdinand’s side.[292] As soon as Ferdinand had recovered the town of Munkats, Balassa was to receive it for his life, with the right of maintaining a certain number of soldiers at Ferdinand’s expense, and, in return, to give up to Ferdinand various towns immediately to the north of Transylvania Proper, which were his possession.
Roostem died in July 1561, and was succeeded by Ali, who proved much more pliant in his negotiations with Busbecq, and the latter at last succeeded in obtaining a peace for eight years. The principal stipulations of the treaty were as follows:[293]
1. Ferdinand to pay an annual tribute of 30,000 ducats, and also the arrears due in respect of the last two years.
2. The Sultan engaged not to attack Ferdinand either directly, or by furnishing assistance to John Sigismund. He also undertook that John Sigismund should respect the territories of Ferdinand.
3. Melchior Balassa and Nicholas Bathory, and others in a similar position, who had returned to their allegiance to Ferdinand, to be included in the peace with their property and lordships, and to be the vassals of Ferdinand and John Sigismund conjointly.
4. If any of Ferdinand’s subjects had been expelled from his property by the adherents of John Sigismund, or vice versâ, no suits or proceedings to recover such property to be taken during the peace.
