Ali Al-Naimi is the former Saudi oil minister - and OPEC kingpin - a position he held for the two decades between August 1995 and May 2016. In this time, Al-Naimi's briefest utterances moved markets. But it wasn't always that way.

Al-Naimi was born into abject poverty as a nomadic Bedouin in the 1930s, just as US companies were discovering vast quantities of oil under the baking Arabian deserts. From his first job as a shepherd boy, aged four, to his appointment to one of the most powerful political and economic jobs in the world, Out of the Desert charts Al-Naimi's extraordinary rise to power.

Described by Alan Greenspan as 'the most powerful man you've never heard of', Al-Naimi's incredible journey proves that anyone can make it - even a poor Bedouin shepherd boy. This is his exclusive inside story of power, politics and oil.

His Excellency Ali Ibrahim Al-Naimi is the former Minister of Petroleum and Mineral Resources for the Kingdom of Saudi Arabia. One of the most powerful economic and political jobs in the world, he held this post from August 1995 to May 2016.

Prior to that he held a wide range of leadership positions in the Kingdom's national oil company, Saudi Aramco. He was the first Saudi national to be named President of the company in 1984 and became the first Saudi CEO in 1988. Al-Naimi joined the company, then called Aramco, as an office boy in 1947. A Bedouin, he was born in the deserts of eastern Arabia in 1935.
