Hamad was appointed Heir Apparent of Qatar in 1977 and held the post until 1995. In the early 1980s, he led the Supreme Planning Council, which sets Qatar's basic economic and social policies. From 1992 Hamad had a growing responsibility for the day-to-day running of the country, including the development of Qatar's oil and natural gas resources. On 27 June 1995, after deposing his father in a palace coup, Hamad became Emir of Qatar and was crowned on 20 June 2000.
