Saudi Arabia [SEP] Foundation of the Saud dynasty
The emergence of what was to become the Saudi royal family, known as the Al Saud, began in Nejd in central Arabia in 1744, when Muhammad bin Saud, founder of the dynasty, joined forces with the religious leader Muhammad ibn Abd al-Wahhab, founder of the Wahhabi movement, a strict puritanical form of Sunni Islam. This alliance formed in the 18th century provided the ideological impetus to Saudi expansion and remains the basis of Saudi Arabian dynastic rule today. The first "Saudi state" established in 1744 in the area around Riyadh, rapidly expanded and briefly controlled most of the present-day territory of Saudi Arabia, sacking Karbala in 1802 and capturing Mecca in 1803, but was destroyed by 1818 by the Ottoman viceroy of Egypt, Mohammed Ali Pasha.
