Saudi Aramco, officially the Saudi Arabian Oil Co., is the world’s most valuable company – and a Saudi Arabian national petroleum and natural gas company, founded in 1933, based in Dhahran, Saudi Arabia.
The origins of Saudi Aramco lie in the oil shortages of World War I and the exclusion of American companies from Mesopotamia by the San Remo Petroleum Agreement of 1920 (this is where France was given a 25% share of Iraqi oil – but that’s another story). The US Republican administration back then, during the times of President Hoover, had popular support for an ‘Open Door’ policy, he himself initiated as secretary of commerce in 1921. Standard Oil of California (SoCal) was among those US companies actively seeking new sources of oil from abroad. This is a photo from the archives of Saudi Aramco in 1935 that I found from this tweet.
