In 1954, the AIOC became the British Petroleum Company. The return of the shah had not meant that British Petroleum was able to monopolise Iranian oil as before. Under pressure from United States, British Petroleum reluctantly accepted membership in a consortium of companies, founded in October 1954, to bring back Iranian oil to the international market. It was incorporated in London as a holding company called 'Iranian Oil Participants Ltd' (IOP). The founding members of IOP included British Petroleum (40%), Gulf (later Chevron, 8%), Royal Dutch Shell (14%), and Compagnie Française des Pétroles (later Total S.A., 6%). The four Aramco partners – Standard Oil of California (SoCal, later Chevron) – Standard Oil of New Jersey (later Exxon, then ExxonMobil) – Standard Oil Co. of New York (later Mobil, then ExxonMobil) – Texaco (later Chevron) – each held an 8% stake in the holding company.
