How Saudi Arabia Became a Nation

The modern Kingdom of Saudi Arabia was unified by Abdulaziz Al Saud (Ibn Saud) between 1902 and 1932:

1. 1902: Recaptured Riyadh (ancestral Al Saud capital) from the Al Rashid clan.
2. 1902–1920s: Conquered Nejd, Al-Hasa, Ha'il, Asir through tribal alliances and warfare.
3. 1924–1925: Captured Hejaz (Mecca, Medina) from the Hashemite Sharif of Mecca.
4. September 23, 1932: Proclaimed the unified Kingdom of Saudi Arabia.

Key factors: Ibn Saud's leadership, tribal support, Wahhabi religious ideology (providing cohesion), and British diplomatic recognition. Oil discovery (1938) later transformed the economy. The kingdom remains an absolute monarchy under the Al Saud dynasty.
