Between 1591 and 1593, Ottoman Bosnian Beglerbeg Telli Hasan Pasha twice attempted to seize the Habsburg fortress of Sisak on Croatia's Military Frontier. After the fall of the key imperial fortress of Bihać in 1592, Sisak was the last stronghold protecting Zagreb. Pope Clement VIII called for a Christian league, and the Croatian Sabor raised a professional relief force of about 5,000 soldiers.
On 22 June 1593, a Habsburg relief army under Ruprecht von Eggenberg, including Croatian forces led by Ban Tamás Erdődy and Carniolan troops under Andreas von Auersperg, launched a surprise attack on the besieging Ottoman forces. Simultaneously, the Sisak garrison sallied forth. The combined assault resulted in the near-total destruction of Hasan Pasha's army; Hasan Pasha himself was killed in the fighting.
The crushing defeat of the Ottoman Bosnian forces at Sisak served as the principal catalyst for the Long Turkish War (1593–1606), a prolonged conflict between the Habsburg Empire and the Ottoman Empire. The battle demonstrated that coordinated Christian resistance could halt Ottoman expansion in Croatia and helped stabilize the Military Frontier as a defensive boundary.
