Abu Bakr al-Baghdadi, the man who rose to become the leader of the Islamic State of Iraq and Syria (ISIS), died on October 27, 2019 at the age of 48. Al-Baghdadi, whose real name was Ibrahim Awwad Ibrahim Ali al-Badri, was born in the city of Samarra in central Iraq in 1971. Al-Baghdadi was believed to have played an integral role in the formation of what would become al-Qaeda in Iraq before assuming leadership of the group in 2010. Three years later, Al-Baghdadi declared the establishment of a caliphate across Iraq and Syria and declared himself its leader. Under Al-Baghdadi's rule, the caliphate rose to its full strength in 2014, with millions of people living within its borders. However, over the course of the next four years, the caliphate's control and power diminished as it sustained military losses to local forces nationwide. Al-Baghdadi himself went into hiding and was subject of a US-led global manhunt. On October 27, 2019, he was killed by US special forces during a raid in Syria. He is survived by his wife and three children.
