A stroke in 1995 left Fahd largely incapacitated. His half-brother, Crown Prince Abdullah, gradually took over most of the king's responsibilities until Fahd's death in August 2005. Abdullah was proclaimed king on the day of Fahd's death and promptly appointed his younger brother, Sultan bin Abdulaziz, the minister of defense and Fahd's "Second Deputy Prime Minister", as the new heir apparent. On 27 March 2009, Abdullah appointed Prince Nayef Interior Minister as his "second deputy prime minister" and Crown Prince on 27 October. Sultan died in October 2011 while Nayef died in Geneva, Switzerland on 15 June 2012. On 23 January 2015, Abdullah died after a prolonged illness, and his half-brother, Crown Prince Salman bin Abdulaziz Al Saud, was declared the new King.
