Kingdom of Saudi Arabia Proclaimed by Royal Decree
Abdulaziz Ibn Saud had spent three decades conquering and consolidating territories across the Arabian Peninsula, capturing Riyadh in 1902 and gradually incorporating Najd, Hejaz, and other regions through military campaigns and alliances. By 1927 the dual kingdoms of Hejaz and Najd existed under his rule. On September 23, 1932, a royal decree unified these domains into a single state named the Kingdom of Saudi Arabia, with Ibn Saud as its founding monarch. The proclamation centralized authority, reduced risks of regional separatism, and established the modern absolute monarchy that endures today.
