BP's origins date back to the founding of the Anglo-Persian Oil Company in 1908, established as a subsidiary of Burmah Oil Company to exploit oil discoveries in Iran. In 1935, it became the Anglo-Iranian Oil Company and in 1954, adopted the name British Petroleum.In 1959, the company expanded beyond the Middle East to Alaska and it was one of the first companies to strike oil in the North Sea. British Petroleum acquired majority control of Standard Oil of Ohio in 1978. Formerly majority state-owned, the British government privatised the company in stages between 1979 and 1987. British Petroleum merged with Amoco in 1998, becoming BP Amoco plc, and acquired ARCO and Burmah Castrol in 2000, becoming BP plc in 2001.
