Crown Prince Mohammad Bin Salman Al Saud

Mohammad Bin Salman Bin Abdul Aziz Al Saud is the Crown Prince of Saudi Arabia, First Deputy Prime Minister of Saudi Arabia and the youngest minister of defense in the world. Mohammad is also chief of the House of Saud Royal Court and chairman of the Council for Economic and Development Affairs. He was appointed Crown Prince in June 2017.
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 bin Hathleen. Prince Mohammad holds a bachelor's degree in law from King Saud University.
On 15 December 2009, Mohammad Bin Salman entered politics as a special advisor to his father when the latter was the governor of Riyadh Province.
In October 2011, Crown Prince Sultan bin Abdul Aziz died, and the current King Salman began his ascent to power by becoming second deputy prime minister and defense minister in November 2011 and making Mohammad bin Salman his private advisor.
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.  
On 29 January 2015, Prince Mohammad was named the chair of the newly established Council for Economic and Development Affairs, replacing the disbanded Supreme Economic Commission. Prince bin Salman was given control over Saudi Aramco by Royal decree 48 hours after being appointed deputy crown prince.
Prince bin Salman's stated concern in 2015-2016 was to reform Saudi's economy towards a more diversified and privatized structure. His reform blueprint, "Vision 2030" details goals and measures in various fields, from developing non-oil revenues and privatization of the economy to e-government and sustainable development. In an interview with Al Arabia he also shared his idea for "Green Cards" for non-Saudi foreigners.
Prince Mohammad Bin Salman's biggest bet was his plan to restore the Saudi kingdom's dominance in global oil markets by driving the new competition into bankruptcy, by keeping the oil price low enough for a long enough period. Saudi Arabia persuaded OPEC to do the same.
