Although King Abdulaziz Al Saud, Ibn Saud as an appellation, the founder of Saudi Arabia in 1901, had an excellent relationship with the British who defended Saudi Arabia from the Turks, he eventually developed even closer ties with the United States. After unifying his country, on September 28, 1928, Bin Saud set about gaining international recognition for Saudi Arabia. The United Kingdom was the first country to recognize Saudi Arabia as an independent state, as the British had provided protection of Saudi territories from the Turks for many years. Saud also hoped to be recognized by the US, which at that time had no interest in Saudi Arabia. Initially, his efforts were rebuffed, but Washington eventually came around, promoted by the fact that Al Saud had obtained recognition from many nations. In May 1931 the U.S. officially recognized Saudi Arabia by extending full diplomatic recognition. At the same time Ibn Saud granted a concession to the U.S. company, Standard Oil of California, allowing them to explore for oil in the country's Eastern Province, al-Hasa. The company gave the Saudi government £35,000 and also paid assorted rental fees and royalty payments.
