The Jebel Akhdar War or the Oman War, also known as Jebel Akhdar rebellion, broke out in 1954 and again in 1957 in Oman, as an effort by the local Omanis in the interior of Oman led by their elected Imam, Ghalib al-Hinai, to protect the Imamate of Oman from the occupation plans of sultan Said bin Taimur, backed by the British government, who were eager to gain access to the oil wells in the interior lands of Oman. Sultan Said received direct financing to raise an armed force to occupy the Imamate of Oman from Iraq Petroleum Company (IPC), a consortium of oil companies that was majorly owned by what is known today as Royal Dutch Shell, Total, ExxonMobil and British Petroleum (BP); the latter was majority-owned by the British government.
