Compare Khalifa bin Hamad Al Thani with another historical figure:
Khalifa bin Hamad oversaw the drafting and promulgation of Qatar's first provisional constitution in 1970, which established the Emir as head of state, created a Council of Ministers, and outlined basic rights. It was later replaced by a permanent constitution in 2004.
Khalifa bin Hamad Al Thani seized power from his cousin, Emir Ahmad bin Ali, on February 22, 1972, while Ahmad was in Iran. The coup was bloodless and received backing from the Al Thani family and the Qatari military.
Emir Khalifa bin Hamad nationalized Qatar's oil industry, taking full control of the Qatar Petroleum Company (now QatarEnergy). This move gave the state direct control over oil revenues, funding infrastructure and social programs.
On June 27, 1995, Emir Khalifa bin Hamad was deposed in a bloodless coup by his son, Hamad bin Khalifa Al Thani, while Khalifa was abroad in Switzerland. Hamad assumed power and initiated major reforms.
