Main article: History of Saudi Arabia § 1900s to 1940s

​Saudi Arabia severed diplomatic contacts with Germany on 11 September 1939, and with Japan in October 1941. Although officially neutral, the Saudis provided the Allies with large supplies of oil. Diplomatic relations with the United States were established in 1943. King Abdul Aziz Al-Saud was a personal friend of Franklin D. Roosevelt. The Americans were then allowed to build an air force base near Dhahran. On 28 February 1945, Saudi Arabia declared war on Germany and Japan, but no military actions resulted from the declaration.[citation needed]
