The order of succession as the Ruler of Qatar is determined by appointments within the Al Thani family.
The former Emir of Qatar, Sheikh Hamad bin Khalifa Al Thani (Arabic: الشيخ حمد بن خليفة آل ثاني), appointed his fourth son, Sheikh Tamim bin Hamad Al Thani (Arabic: الشيخ تميم بن حمد آل ثاني), as heir apparent on 8 August 2003, after his older son Sheikh Jassim bin Hamad Al-Thani (who held the position between 1996 and 2003) renounced his rights to the throne in favour of Sheikh Tamim.
