Khalid of Saudi Arabia was the King of Saudi Arabia from March 1975 to his death on June 1982. The fifth male child of his father Ibn Saud, the first monarch and founder of Saudi Arabia, he succeeded the throne after his predecessor, King Faisal, was assassinated and his older brother declined to the line of succession. His reign saw immense development and growth in infrastructure, education and healthcare, apart from huge increases in revenue from oil exports. He consolidated political power of the ruling family in the cabinet, restricting the power of Sudairi Seven. He also made significant efforts to establish Islamic solidarity through foreign relations. His reign witnessed several internal and international socio-political events including the capture of the Grand Mosque in Mecca, the Iranian Revolution, the Soviet invasion of Afghanistan, and the assassination of Egyptian President Anwar Sadat. Personally, he was well-liked by his family members, religious leaders, and tribal chiefs for his warm and cheerful nature.
