Education (also name universities attended, if any); note any relevant experiences while a student
Baghdadi has obtained several advanced degrees in Islamic studies, “including a bachelor's degree in Islamic studies from the University of Baghdad in 1996, and a Master's and PhD in Koranic studies from Iraq's Saddam University for Islamic Studies in 1999 and 2007 respectively.”
Ever married? If yes, age of first marriage
He married in roughly 2002.
He has six children.
He is a Sunni Muslim.
Elite Family background
No. Baghdadi comes from a lower-middle-class family that does not hold elite status. The ISIS leader’s family is very pious and they even claim to be direct decedents of the Prophet Muhammad. However, claiming to be a decedent of the Prophet is not uncommon, especially among religious leadership in Islam (although usually more common in Shia circles). 
Despite the fact that Baghdadi’s family has a history of religiosity, some of his family joined the Baath Party.  This may help explain why former Baath Party members have played such a prominent role (despite their inherent rivalry) in the ISIS expansion since Baghdadi became the leader of ISIS.
Political affiliations and intellectual circles; note any relevant social connections made
Baghdadi was a member of the Muslim Brotherhood while in graduate school.
Through this organization Baghdadi gravitates towards the most radical elements of the brotherhood, the jihadist Salafis. His brother Jum’a and mentor Muhammad Hardan (a veteran of the Afghan war against the Soviets), are also members of this movement.
Physical and mental health
No, there is no evidence of poor physical or mental health.
Pre-militant leader occupation
He was an activist.
Experience in a state military, and role; any relevant social ties
No, based on multiple biographical sources there is no evidence of state military experience.
Experience in a nonstate military, and role; any relevant social ties
Yes. “Baghdadi helped found Jaysh Ahl al-Sunna wa-l-Jamaah (Army of the People of the Sunna and Communal Solidarity), an insurgent group that fought U.S. troops and their local allies in northern and central Iraq.” However, given his reputation as a theologian and recruiter, evidence of actual combat experience is thin at best.
Combat experience prior to assuming resistance organization leadership?
No, based on multiple biographical sources there is no evidence of combat experience.
Held government position prior to assuming leadership?
No, there is no evidence he held a government position.
Lived in exile?
Yes, he has fled Iraq and is hiding in the desert in Syria.
No, based on multiple biographical sources there is no evidence of study abroad.
Did the leader receive military training abroad?
No, there is no evidence of military training abroad.
Did the leader have extensive work experience abroad?
No, there is no evidence of him having extensive working experience abroad.
Serve time in prison? Social connections during that time?
Yes. Beginning in 2004 Baghdadi was arrested in Fallujah and eventually taken to Camp Bucca for the next ten months. His time in Bucca allows him to meet and make connections other Sunni radicals, many of whom “would later rise with him through the ranks of the Islamic State.”
“By the time Baghdadi was released on December 8, 2004, he had a virtual Rolodex for reconnecting with his co-conspirators and protégés: they had written one another’s phone numbers in the elastic of their underwear.” During his time in Bucca, “Baghdadi would almost certainly have met jihadists in Zarqawi’s circle.”
Was there an assassination attempt on the leader by the state?
Yes, there was an attempt in 2015.
Cause of Death?
Primary language, and other languages spoken as adult
His primary language was Arabic, and there is no evidence of English as a first or second language.
