Definition
The Siege of Diriyah was a military operation conducted by the Ottoman‑Egyptian forces under the command of Ibrahim Pasha that culminated in the capture and destruction of Diriyah, the capital of the First Saudi State, in 1818.
Overview
In the early 19th century, the First Saudi State, founded by Muhammad ibn Saud and his successors, had expanded across much of the Arabian Peninsula and adopted a strict Wahhabi interpretation of Islam. This expansion threatened Ottoman authority in the region, prompting the Ottoman Empire to enlist its Egyptian vassal, Muhammad Ali Pasha, to suppress the Saudi movement.
After a series of engagements in 1813–1817, Ibrahim Pasha led a well‑equipped expedition into the Najd region. The forces laid siege to Diriyah in late 1817, employing artillery and engineering works to breach the city’s fortifications. Following a protracted assault, Diriyah fell in early 1818. The aftermath included the demolition of much of the town, the capture and execution of the Saudi leader Abdulaziz bin Saud, and the incorporation of the area into Ottoman‑Egyptian control.
Etymology/Origin
The name “Diriyah” derives from the Arabic دِرْيَة (Diryah), the name of the clan that founded the settlement in the 15th century. The term “siege” refers to the military tactic of surrounding and isolating a fortified place to compel its surrender.
