On November 13, 1594, Mihai Viteazul ordered the execution of Turkish creditors in Bucharest, marking the start of an anti-Ottoman uprising. This act severed diplomatic ties with the Ottoman Empire and initiated a rebellion against their rule. The Wallachian state was under Ottoman suzerainty, burdened by debts and taxes. Mihai sought support from Christian powers for a revolt and confiscated the creditors' wealth to fund his military efforts. Concurrently, his forces attacked and captured the Ottoman garrison in Giurgiu. This decisive action set the stage for future battles against the Ottomans, including Călugăreni and Giurgiu.
