Ottoman–Wahhabi War

The Ottoman–Wahhabi War and also known as the Ottoman–Saudi War, was fought from early 1811 to 1818, between Egypt Eyalet under the reign of Muhammad Ali Pasha (nominally under Ottoman rule) and the army of the First Saudi State. It resulted in the destruction of the First Saudi State.

Background
The Wahhabi movement was part of a fundamentalist/revisionist movement within Islam that would lead to creation of the first Saudi State, and its crushing by the Ottoman empire’s Egyptian viceroy Muhammad Ali Pasha.

Muhammad ibn ‘Abd al-Wahhab and the amir Muhammad ibn Sa’ud launched their campaign to reform Islam and consolidate power in Arabia from their power-base in Diriyah. By 1805, the Wahhabis controlled Mecca and Medina, had attacked Karbala and the Imam Husayn Shrine. The Wahhabis also attacked Ottoman trade caravans which interrupted the Ottoman finances. The Saudi amir denounced the Ottoman sultan and called into question the validity of his claim to be caliph and guardian of the sanctuaries of the Hejaz and the Ottoman empire instructed the upstart Muhammad ‘Ali, viceroy of Egypt, to fight the Wahhabis. The Ottoman empire was suspicious of Muhammed Ali’s ambition, and thought that by ordering Ali against the Wahhabis, the defeat of either would be beneficial.

Campaigns
Muhammad ‘Ali was ordered to crush the Saudi state as early as December 1807 by Sultan Mustafa IV, however internal strife within Egypt prevented him from giving full attention to the Wahhabis. The Egyptians were not able to recapture the holy cities until 1811.

However, it would take until September 1818 for the Wahhabi state to end with the surrendering of the its leaders. Ibrahim Pasha, Muhammad ‘Ali’s son, had taken over the campaign in 1817. Gaining the support of the volatile Arabian tribes by skillful diplomacy and lavish gifts, he advanced into central Arabia to occupy the towns of Unaizah and Buraidah. Joined now by most of the principal tribes, he appeared before the Saudi capital Diriyah in April 1818. With their march to Diriyah plagued by Wahhabi attacks, they arrived in Diriyah in April 1818. It took until September for the Wahhabis to surrender, in part due to Ibrahim’s poorly trained army. Diriyah was destroyed on June 1819, and Egyptian garrisons were posted in the principal towns. The head of the Wahhabi state, Amir ‘Abd Allah, was sent to Constantinople to be executed.

Aftermath
Amir ‘Abd Allah, as head of the Wahhabi state, was sent for execution to Istanbul, while most of the political leaders were treated well. The empire was far more harsh with the religious leaders that inspired the Wahhabi movement. The execution of Sulayman ibn ‘Abd Allah and other religious notables reflects the resentment of these extremist views. Religious leaders were thought to be uncompromising in their beliefs and therefore a much bigger threat than political leaders.
