The Anglo-Persian Oil Company (APOC) was a British company founded in 1909 following the discovery of a large oil field in Masjed Soleiman, Persia (Iran). The British government purchased 51% of the company in 1914, gaining a controlling number of shares, effectively nationalizing the company. It was the first company to extract petroleum from Iran. In 1935 APOC was renamed the Anglo-Iranian Oil Company (AIOC) when Reza Shah formally asked foreign countries to refer to Persia by its endonym Iran.

Reza Shah Pahlavi was an Iranian military officer and the founder of the Pahlavi dynasty. As a politician, he previously served as minister of war and prime minister of Qajar Iran and subsequently reigned as Shah of Pahlavi Iran from 1925 until he was forced to abdicate after the Anglo-Soviet invasion of Iran in 1941. He was succeeded by his eldest son, Mohammad Reza Shah. A modernizer, Reza Shah clashed with the Shia clergy, but also introduced many social, economic, and political reforms during his reign, ultimately laying the foundation of the modern Iranian State. Therefore, he is regarded by many as the founder of modern Iran.
