Koca Sinan Pasha
The Diet of Hungary voted an extraordinary tax to finance the defense of Slavonia and Croatia against the Ottomans in early 1593. The Diet appointed Sigismund to collect the tax in Upper Hungary. After the Ottoman Grand Vizier, Koca Sinan Pasha, invaded Transdanubia, rumours about his plan to transform Upper Hungary into a "voivodate" (vassal state) were spreading. Sigismund urged the influential Nicholas Pálffy to persuade Rudolph I to launch a counter-invasion against the Ottomans without delay. He also suggested that Transylvania, Moldavia and Wallachia should be included in an anti-Ottoman coalition.
