Mohammad bin Salman Al Saud is the Crown Prince of Saudi Arabia, Deputy Prime Minister of Saudi Arabia and the youngest minister of defense in the world.
King Salman bin Abdulaziz Al Saud dismissed his nephew Mohammed bin Naif as crown prince and replaced him with his son Mohammed bin Salman as first in line to the throne.
Mohammad is also chief of the House of Saud royal court, and chairman of the Council for Economic and Development Affairs.
Mohammad bin Salman Al Saud was born on 31 August 1985 in Jeddah. He is the son of King Salman from his third spouse, Fahda bint Falah bin Sultan.
Prince Mohammad holds a bachelor degree in law from King Saud University.
After graduating from college, Mohammad bin Salman spent several years in the private sector before becoming the personal aide of his father. He worked as a consultant for the Experts Commission, working for the Saudi Cabinet.
Mohammad bin Salman entered politics as a special advisor to his father when the latter was the governor of Riyadh Province.
On 23 January 2015, King Abdullah died, Salman took the throne and Prince Mohammad was appointed minister of defense. He was also named as the secretary general of the Royal Court on the same date.
The first major event in his tenure as defense minister was Operation Decisive Storm, part of the Saudi Arabian-led intervention in Yemen, an operation against Houthi rebels in Yemen, experiencing the 2015 Yemeni Civil War. As defence minister, Prince Mohammad has been heavily involved in the Saudi Arabian-led intervention in Yemen.
Mohammad bin Salman was appointed Crown Prince on 21 June 2017, following his father's decision to depose Muhammad bin Nayef, making him heir apparent to the throne.
His biggest bet was his plan to restore Saudi Kingdom's dominance in global oil markets by driving the new competition into bankruptcy keeping the oil price low enough for a long enough period of time.
Mohammed bin Salman has a lavish lifestyle. One incident which illustrates this is his spur of the moment purchase of the yacht Serene from Russian vodka tycoon Yuri Scheffler for a price of €500 million reported by New York Times magazine.
