Al-Saud family revolted against the Ottomans

In 1811, the fundamentalist Wahhabis of Arabia, led by the al-Saud family, revolted against the Ottomans. Unable to defeat the Wahhabi rebels, the Sublime Porte had Muhammad Ali Pasha of Kavala, the vali (governor) of the Eyalet of Egypt, tasked with retaking Arabia, which ended with the destruction of the Emirate of Diriyah in 1818. The suzerainty of Serbia as a hereditary monarchy under its own dynasty was acknowledged de jure in 1830.
